3. Tallest Tower Team Building Activity


team

A team consists of a group of people, committed to a common goal that no one individual can achieve alone. The focus of teams and teamwork is on mutual accountability and performance.

The concept of teamwork presents itself differently across the projects, programmes and portfolios as the make-up and environment of the teams vary. Within the P3 environment there will be a hierarchy of different teams. The obvious example is a project team within a programme, a programme team within a portfolio and the overall portfolio team.

Tower building activity was conducted in Computer Engg diploma class of Pimpri Chinchwad Polytechnic.

The activity was conducted to illustrate teamwork, planning, and cooperation. Small groups were created in a class. It worked as a competition between several groups was set to see who can finish first and with the highest and durable tower. This was a great activity to help teams bond, or to illustrate team process.

Following are some glips of Activity in Computer Department of Pimpri Chinchwad polytechnic:

4. Computer Network


Maharashtra state board of Technical education (M.S.B.T.E, Mumbai) introduces COMPUTER NETWORK SUBJECT in 4th semester in the curriculum for COMPUTER branch WHICH IS BEST COMPUTER ENGINEERING DIPLOMA COLLEGE in pune.

At Pimpri Chinchwad polytechnic, one of best polytechnic in Pune where third year students developed models as a part of curriculum. This activity not only develops skill to work in a team but also develop the habit to complete the task in prescribed time.

A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server.

team

Types of Networks:


  • LAN
  • WAN
  • MAN
  • PAN
  • CAN

Advantages of networking:-


1. Easy Communication and Speed

It is very easy to communicate through a network. People can communicate efficiently using a network with a group of people. They can enjoy the benefit of emails, instant messaging, telephony, video conferencing, chat rooms, etc.


2. Ability to Share Files, Data and Information

This is one of the major advantages of networking computers. People can find and share information and data because of networking. This is beneficial for large organizations to maintain their data in an organized manner and facilitate access for desired people.


3. Sharing Hardware

Another important advantage of networking is the ability to share hardware. For an example, a printer can be shared among the users in a network so that there’s no need to have individual printers for each and every computer in the company. This will significantly reduce the cost of purchasing hardware.


4. Sharing Software

Users can share software within the network easily. Networkable versions of software are available at considerable savings compared to individually licensed version of the same software. Therefore large companies can reduce the cost of buying software by networking their computers.


5. Security

Sensitive files and programs on a network can be password protected. Then those files can only be accessed by the authorized users. This is another important advantage of networking when there are concerns about security issues. Also each and every user has their own set of privileges to prevent them accessing restricted files and programs.


6. Speed

Sharing and transferring files within networks is very rapid, depending on the type of network. This will save time while maintaining the integrity of files.


7. Centralized Data

The data of all network users can be saved on hard disk of the server computer. This will help users to use any workstation in a network to access their data. Because data is not stored on workstations locally.


The subject also covers various employability aspects so that second year student can take decision either to do job or to go for higher education.

5. Tree Plantation on 1st July 2017


As we all know 1st july is celebrated as a tree plantation day in India. In 2017 Maharashtra government decided to plant 2 crores trees on July 1st. As a part of this celebration decided by government, we at Pimpri Chinchwad polytechnic which is Best polytechnic college in Maharashtra, conducted tree planation drive.


team

Tree Plantation in college of Polytechnic in Pimpri Chinchwad.


Without oxygen we cannot live for a moment even. Without oxygen, the animal world will die away. Trees make the oxygen and spreads it in the air. While inhaling air we take the oxygen with it into our bodies and live in life. Carbon dioxide makes our atmosphere or rather our environment poisonous for us. Trees consume this carbon dioxide and thereby makes our environment safe for us.


Trees contribute to their environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe.


team

Importance of Trees:

The trees are extremely important and have always been needed for developing the human condition and lifestyle. It doesn't a make bigger believe that without trees we humans would not exist on this beautiful earth. So, trees are important for life as we know it and are the earth troops creating up an environmental Frontline. There are various importances of trees such as Trees Produce Oxygen, Trees Clean the Soil, Trees Control Noise Pollution, Trees Slow Storm Water Runoff, Trees Are Carbon Sinks, Trees, Shade and Cool, Trees Act as Windbreaks, Trees Fight Soil Erosion, Trees Increase Property Values and many more.

As already descried the importance of trees , there are also numeral of the benefits of the trees except mention above such as Save Water, conserve energy, reduce violence, add unity, provide wood and save earth from an earthquake. You should participate in PlantyourTrees.com to “Save Trees to Save Life”. Save trees to reduce global warming, reduce the carbon footprint and pollution as well as a clean environment.

Selection of trees for plantation:

We should make good selection of trees to be planted, in consideration of the nature of land and the kind of climate. Coconut trees grow well in the sea-coasts. Plantain trees grow well near the ponds. We should know which place is fit for which tree. To know this we should get our soil tested by the experts and plant the kinds of trees accordingly. Collection of plants to be planted should be made from the Government nurseries in consultation with the experts there.

After-care:

Only planting the trees is not enough. Because, planted trees may be destroyed by animals or otherwise, or may die for regular service of water. So we should be particular about the after-care of the planted trees. We should be very careful about the newly-planted trees.

6. Threads in JAVA


What are Java Threads?

  • Facility to allow multiple activities within a single process
  • Referred as lightweight process
  • A thread is a series of executed statements
  • Each thread has its own program counter, stack and local variables
  • A thread is a nested sequence of method calls
  • Its shares memory, files and per-process state

team

In Pimpri Chinchwad Polytechnic in Computer Science Department gives full practical as well as theoretical knowledge about Threads in Java. Students develop their own programming knowledge about Java coding during practical sessions.

What’s the need of a thread or why we use Threads?

  • To perform asynchronous or background processing
  • Increases the responsiveness of GUI applications
  • Take advantage of multiprocessor systems
  • Simplify program logic when there are multiple independent entities

What happens when a thread is invoked?

When a thread is invoked, there will be two paths of execution. One path will execute the thread and the other path will follow the statement after the thread invocation. There will be a separate stack and memory space for each thread.


Risk Factor

  • Proper co-ordination is required between threads accessing common variables [use of synchronized and volatile] for consistence view of data
  • overuse of java threads can be hazardous to program’s performance and its maintainability.

Threads in Java

Java threads facility and API is deceptively simple:

Every java program creates at least one thread [ main() thread ]. Additional threads are created through the Thread constructor or by instantiating classes that extend the Thread class.


Thread creation in Java

Thread implementation in java can be achieved in two ways:

  • Extending the java.lang.Thread class
  • Implementing the java.lang.Runnable Interface
  • .

By extending thread class

  • The class should extend Java Thread class.
  • The class should override the run() method.
  • The functionality that is expected by the Thread to be executed is written in the run() method.

void start(): Creates a new thread and makes it runnable.

void run(): The new thread begins its life inside this method.


team

Example.

public class MyThread extends Thread {
public void run(){
System.out.println("thread is running...");
}
public static void main(String[] args) {
MyThread obj = new MyThread();
obj.start();
}

2) By Implementing Runnable interface

  • The class should implement the Runnable interface
  • The class should implement the run() method in the Runnable interface
  • The functionality that is expected by the Thread to be executed is put in the run() method

Example:

public class MyThread implements Runnable {
public void run(){
System.out.println("thread is running..");
}
public static void main(String[] args) {
Thread t = new Thread(new MyThread());
t.start();
}experts there.

Thread life cycle in java


team

  • The start method creates the system resources, necessary to run the thread, schedules the thread to run, and calls the thread’s run method.
  • A thread becomes “Not Runnable” when one of these events occurs:
    • If sleep method is invoked.
    • The thread calls the wait method.
    • The thread is blocking on I/O.
  • A thread dies naturally when the run method exits.

Pimpri Chinchwad Polytechnic is the best computer diploma engg college in Pune which provides vast knowledge about programming, where many sessions are conducted for students to gain knowledge about coding.

Blocking Threads

  • When reading from a stream, if input is not available, the thread will block
  • Thread is suspended (“blocked”) until I/O is available
  • Allows other threads to automatically activate
  • When I/O available, thread wakes back up again
    • Becomes “runnable” i.e. gets into ready state.

Grouping of threads

  • Thread groups provide a mechanism for collecting multiple threads into a single object and manipulating those threads all at once, rather than individually.
  • To put a new thread in a thread group the group must be explicitly specified when the thread is created
  • .
    • public Thread(ThreadGroup group, Runnable runnable)
    • public Thread(ThreadGroup group, String name)
    • public Thread(ThreadGroup group, Runnable runnable, String name)

Target keywords: thread life cycle in java, java threading tutorial, using threads in java, javathread run.

These sessions are conducted under Java Programming Lecture in Pimpri Chinchwad Polytechnic which is one of the best college in Pune

7. COMPUTER SECURITY


Computer security, also known as cyber security or IT security, is the protection of computer systems from the theft or damage to their hardware, software or information, as well as from disruption or misdirection of the services they provide.

Cyber security includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection. Also, due to malpractice by operators, whether intentional, accidental, IT security is susceptible to being tricked into deviating from secure procedures through various methods. The field is of growing importance due to the increasing reliance on computer systems and the Internet, wireless networks such as Bluetooth and Wi-Fi, and the growth of "smart" devices, including smartphones, televisions and tiny devices as part of the Internet of Things.

8. MANAGEMENT INFORMATION SYSTEMS (MIS)


Management information system (MIS) refers to the processing of information through computers and other intelligent devices to manage and support managerial decisions within an organization. The concept may include systems termed transaction processing system, decision support system, expert system, or executive information system. The term MIS is often used in the academic study of businesses and has connections with other areas, such as information systems, information technology, informatics, e-commerce and computer science.

Basically (MIS) is a computerized database of financial information organized and programmed in such a way that it produces regular reports on operations for every level of management in a company or different business areas. It is usually also possible to obtain special reports from the system easily. Now a days this system is popularly applicable in education system of organizations like Pimpri Chinchwad polytechnic, Akurdi , Pune for information storing, processing and retrieving all type of data related with educational system.

EVOLUTION :

The first era (mainframe and minicomputer) was ruled by IBM and their mainframe computers; these computers would often take up whole rooms and require teams to run them—IBM supplied the hardware and the software. As technology advanced, these computers were able to handle greater capacities and therefore reduce their cost. Smaller, more affordable minicomputers allowed larger businesses to run their own computing centers in-house / on-site / on-premises.

The second era (personal computer) began in 1965 as microprocessors started to compete with mainframes and minicomputers and accelerated the process of decentralizing computing power from large data centers to smaller offices. In the late 1970s, minicomputer technology gave way to personal computers and relatively low-cost computers were becoming mass market commodities, allowing businesses to provide their employees access to computing power that ten years before would have cost tens of thousands of dollars. This proliferation of computers created a ready market for interconnecting networks and the popularization of the Internet.

As technological complexity increased and costs decreased, the need to share information within an enterprise also grew—giving rise to the third era (client/server), in which computers on a common network access shared information on a server. This lets thousands and even millions of people access data simultaneously. The fourth era (enterprise) enabled by high speed networks, tied all aspects of the business enterprise together offering rich information access encompassing the complete management structure. Every computer is utilized.

The fifth era (cloud computing) is the latest and employs networking technology to deliver applications as well as data storage independent of the configuration, location or nature of the hardware. This, along with high speed cellphone and Wi-Fi networks, has led to new levels of mobility in which managers may access the MIS remotely with laptops, tablet computers and smartphones.

ADVANTAGES & APPLICATIONS

The following are some of the advantages that can be attained using:

  • Companies are able to identify their strengths and weaknesses due to the presence of revenue reports, employees' performance record etc. Identifying these aspects can help a company improve its business processes and operations.
  • Giving an overall picture of the company and acting as a communication and planning tool.
  • The availability of customer data and feedback can help the company to align its business processes according to the needs of its customers. The effective management of customer data can help the company to perform direct marketing and promotion activities.
  • MIS can help a company gain a competitive advantage. Competitive advantage is a firm's ability to do something better, faster, cheaper, or uniquely, when compared with rival firms in the market.
  • MIS report help to take decision and action on certain object with quick time.

The following are some of the Applications that can be attained using:

  • Enterprise systems : This is also known as “enterprise resource planning (ERP) systems” provide integrated software modules and a unified database that personnel use to plan, manage, and control core business processes across multiple locations. Modules of ERP systems may include finance, accounting, marketing, human resources, production, inventory management, and distribution.
  • Supply chain management (SCM) systems enable more efficient management of the supply chain by integrating the links in a supply chain. This may include suppliers, manufacturers, wholesalers, retailers, and final customers.
  • Customer relationship management (CRM) systems help businesses manage relationships with potential and current customers and business partners across marketing, sales, and service.
  • Knowledge management system (KMS) helps organizations facilitate the collection, recording, organization, retrieval, and dissemination of knowledge. This may include documents, accounting records, unrecorded procedures, practices, and skills. Knowledge management (KM) as a system covers the process of knowledge creation and acquisition from internal processes and the external world. The collected knowledge is incorporated in organizational policies and procedures, and then disseminated to the stakeholders.

Hence in today’s digital word advanced computer engineering colleges like Pimpri Chinchwad polytechnic, Akurdi. is used MIS ERP as a repository for data collection, processing, analyzing and reporting of educational information including schools, students, teachers and staff. This information is used by NGOs, researchers, donors and other education stakeholders for research; policy and planning; monitoring and evaluation; and decision making in education sector. In COMPUTER branch of BEST COMPUTER ENGINEERING DIPLOMA COLLEGE, Pune MIS information is specifically used to monitor not only the performance of an education system but also performance of students and to manage the distribution and allocation of educational resources and services between them.

10. Binary Tree Traversal


Traversal is a process to visit all the nodes of a tree and may print their values too. Because, all nodes are connected via edges (links) we always start from the root (head) node. That is, we cannot randomly access a node in a tree. There are three ways which we use to traverse a tree −

  • In-order Traversal
  • Pre-order Traversal
  • Post-order Traversal

Generally, we traverse a tree to search or locate a given item or key in the tree or to print all the values it contains.

In Pimpri Chinchwad Polytechnic in Computer Science Department gives full practical as well as theoretical knowledge about Binary Tree Traversals in Data Structures. Students develop their own programming knowledge about C coding during practical sessions.

In-order Traversal

In this traversal method, the left subtree is visited first, then the root and later the right sub-tree. We should always remember that every node may represent a subtree itself.

If a binary tree is traversed in-order, the output will produce sorted key values in an ascending order.

We start from A, and following in-order traversal, we move to its left subtree B. B is also traversed in-order. The process goes on until all the nodes are visited. The output of inorder traversal of this tree will be −
D → B → E → A → F → C → G

Algorithm
Until all nodes are traversed −
Step 1 − Recursively traverse left subtree.
Step 2 − Visit root node.
Step 3 − Recursively traverse right subtree.

best IT Department of Pimpri Chinchwad Polytechnic was established in the year 2001 and has grown over the years into a competent department with state of the art computing facilities, and dedicated faculty.

Pre-order Traversal

In this traversal method, the root node is visited first, then the left subtree and finally the right subtree.

We start from A, and following pre-order traversal, we first visit A itself and then move to its left subtree B. B is also traversed pre-order. The process goes on until all the nodes are visited. The output of pre-order traversal of this tree will be −
A → B → D → E → C → F → G

Algorithm
Until all nodes are traversed −
Step 1 − Visit root node.
Step 2 − Recursively traverse left subtree.
Step 3 − Recursively traverse right subtree.

best IT Department of Pimpri Chinchwad Polytechnic was established in the year 2001 and has grown over the years into a competent department with state of the art computing facilities, and dedicated faculty.

Post-order Traversal

In this traversal method, the root node is visited last, hence the name. First we traverse the left subtree, then the right subtree and finally the root node.

We start from A, and following pre-order traversal, we first visit the left subtree B. B is also traversed post-order. The process goes on until all the nodes are visited. The output of post-order traversal of this tree will be −
D → E → B → F → G → C → A

Algorithm
Until all nodes are traversed −
Step 1 − Recursively traverse left subtree.
Step 2 − Recursively traverse right subtree.
Step 3 − Visit root node.

11. Relational Database Management System


A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as invented by Edgar F.Codd, of IBM's San Jose Research Laboratory. 

To acquire basic knowledge about RDMS students can take admission in best polytechnic college in Pune. In Polytechnic, MSBTE Curriculum Relational Database Management System subject is present in that every Organization like shopping mall, hospital, banking, institutes, Industry etc. needs to share huge amount of data in effective manner. This subject enables to create, store,modify and extract information from a database. Relational database management system has been developed to manage the information stored in the database. After learning this subject student will be able to use RDBM package as a backend for developing database applications.

Database Management System:-

Databases store sets of data about products, customers, orders and other facets of business operations so the information can be used in transaction processing or business intelligence and analytics applications. As its name indicates, a database management system is software that supports the development, administration and use of databases.

best IT Department of Pimpri Chinchwad Polytechnic was established in the year 2001 and has grown over the years into a competent department with state of the art computing facilities, and dedicated faculty.

Relational Database Management System:-

  • A relational database management system (RDBMS) is a kind of DBMS that was created in the 1970s and has become the dominant technology for managing databases since then.
  • Its hallmark is a row-based table structure that connects related data elements to one another and provides transactional integrity to maintain data accuracy and consistency.
  • Another common RDBMS attribute is support for using the Structured Query Language (SQL), a standardized programming language for writing queries to modify databases and retrieve data from them.
  • The top RDBMS products in the market include Oracle Database, Microsoft SQL Server, IBM DB2 and MySQL, an open source database platform that is owned by Oracle; other notable ones are SAP HANA another open source technology.

Difference between DBMS & RDMS

Sr. No.

DBMS

RDBMS

1

DBMS application store data as file.

RDBMS application store data in tabular form

2

Normalization is not present in DBMS.

Normalization is present in RDBMS

3

DBMS does not apply any security with regards to data manipulation.

RDMS define the integrity constraint for the purpose of ACID.

13. Mobile Cloud Computing


In today's computing world, different technologies have emerged. These have grown to support the existing computer networks all over the world. Mobile Computing is one of technology that allows transmission of data, voice and video via a computer or any other wireless enabled device without having to be connected to a fixed physical link. With mobile computing, we find that the need to be confined within one physical location has been erased.

With this mobile communication “mobile cloud computing” is emerging technology which is growing day by day. The portability of different mobile & portable devices ensure and enable the users to access all services as if they were in the internal network of their company or college like Pimpri Chinchwad polytechnic, Akurdi, Pune where anyone can use wireless network for information sharing & searching. 

Mobile Cloud Computing (MCC) is a combination of mobile computing, cloud computing and mobile internet. In MCC data processing and storage is transferred from the mobile devices to powerful and centralized computing platform located in clouds. Cloud can be accessed with the help of wireless connections via web browser on the mobile devices.

LECTURE

Mobile cloud computing has many advantages:

  • With Mobile cloud computing sharing information and applications is easy without the need of complex and costly hardware and software because the business computations are conducted on the cloud.
  • Mobile phones features and functionality are now enhanced through new cloud applications.
  • Since the access point to mobile cloud computing is through a browser and not a mobile operating system there is ease of access.
  • To build mobile cloud applications is cheaper for cloud computing vendors because of economies of scale, i.e access to all smartphone devices, one application can be shared and accessed by many smartphone users.
  • Broader reach, since mobile cloud applications can be accessed through a browser, the cloud computing applications can be reached by all mobile users anywhere, anytime. So it has broader reach as long as the mobile has access to the internet.

The goal of mobile cloud computing is to provide rich mobile computing through unified communication between front users (cloud mobile users) and end users (cloud providers) regardless of assorted, wireless environment and in global roaming. Mobile cloud computing aims to empower the mobile user by providing a seamless and rich functionality, regardless of the resource limitations of mobile devices. Although still in its infancy, mobile cloud computing could become the dominant model for mobile applications in the future. To acquire basic knowledge about networking, cloud computing, MCC & other related terms students can take admission in COMPUTER branch of BEST COMPUTER ENGINEERING DIPLOMA COLLEGE,Pune. where different programming & networking related subject are covered by MSBTE Curriculum which helps students to improve their knowledge and provide a good platform for bright future in IT industry.

14. Wireless Communication Technology


Wireless tech is new era which brings world more close & become one of the largest carriers of digital data in the world today. Today wireless technology is responsible for the easy and efficient functioning of different sectors of corporate & even in education system also. Every small and large industries or enterprises are depends on wireless technology in some part of their infrastructure to grow & develop well business.

Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors.  Some of the devices used for wireless communication are cordless telephones, mobiles, GPS units, wireless computer parts, and satellite television etc. In the upcoming years, wireless technology is set to include even more devices and features. Wireless charging for example has been one of those applications which would not even have been thought possible years ago. Even we have seen that cellphones which were initially limited in range and bandwidth now being able to equal computers in their ability to receive and process data. Wireless technology and handheld devices have gone light years ahead in a really short span of time. Now a days this technology is popularly applicable in education system of organizations like Pimpri Chinchwad polytechnic, Akurdi, Pune for communication between staff- students & staff- parents to share all type of information related with educational system.

Mobile Cloud Computing (MCC) is a combination of mobile computing, cloud computing and mobile internet. In MCC data processing and storage is transferred from the mobile devices to powerful and centralized computing platform located in clouds. Cloud can be accessed with the help of wireless connections via web browser on the mobile devices.

LECTURE

Wireless Network Evolution

Wireless mobile communication system has become more popular due to rapid changes in mobile technology. Fast development of wireless communication systems are due to very high increase in telecoms customers. The revolution of mobile communications is from 1G-the first generation, 2G-the second generation, 3G-the third generation, 4G-the fourth generation, 5G-the fifth generation.

Advantages of Wireless Communication:

Wireless communication has the following advantages:

i. Communication has enhanced to convey the information quickly to the consumers, like in COMPUTER branch of BEST COMPUTER ENGINEERING DIPLOMA COLLEGE,Pune , student’s daily practical & lectures attendance will send on parents mobile.

ii. Working professionals can work and access Internet anywhere and anytime without carrying cables or wires wherever they go. This also helps to complete the work anywhere on time and improves the productivity.

iii. Doctors, workers and other professionals working in remote areas can be in touch with medical centers through wireless communication.

iv. Urgent situation can be alerted through wireless communication. The affected regions can be provided help and support with the help of these alerts through wireless communication.

v. Wireless networks are cheaper to install and maintain. Hence in today’s digital word advanced computer engineering colleges like Pimpri Chinchwad polytechnic, Akurdi is use such technology for collecting & sharing information for research & communication.

Future of wireless

While there are no particular standards in place right now when it comes to the next generation of cellular communication (5G), we can expect to have more concrete plans laid out in 2020. The estimated speeds on the networks of the future will range from a low figure of 3.6 GBPS to over 10 GBPS. These are massive numbers but they seem possible when you factor in the rapid growth of wireless technology.

Conclusion

The swift development of wireless has enabled so many parallel technologies, increased productivity and even saved countless lives. The future for wireless looks set to include even more applications which can give humans an edge. Another positive of this growth is that wireless technology has gotten really cheap which means that more people have access to it. Wireless innovations have made the world a much smaller place!

15. Artificial Intelligence


What is artificial intelligence (AI), and what is the difference between general AI and narrow AI?There seems to be a lot of disagreement and confusion around artificial intelligence right now.

We’re seeing ongoing discussion around evaluating AI systems with the Turing Test, warnings that hyper-intelligent machines are going to slaughter us and equally frightening, if less dire, warnings that AI and robots are going to take all of our jobs.

LECTURE

AI: A textbook definition

The starting point is easy. Simply put, artificial intelligence is a sub-field of computer Engineering. To study more in computer science and engineering anyone can prefer Best Diploma engineering college in Maharashtra. Its goal is to enable the development of computers that are able to do things normally done by people -- in particular, things associated with people acting intelligently.

If we start with this definition, any program can be considered AI if it does something that we would normally think of as intelligent in humans.  How the program does it is not the issue, just that is able to do it at all. That is, it is AI if it is smart, but it doesn’t have to be smart like us.

Strong AI & weak AI :-

It turns out that people have very different goals with regard to building AI systems, and they tend to fall into three camps, based on how close the machines they are building line up with how people work.

For some, the goal is to build systems that think exactly the same way that people do. Others just want to get the job done and don’t care if the computation has anything to do with human thought. And some are in-between, using human reasoning as a model that can inform and inspire but not as the final target for imitation.

The work aimed at genuinely simulating human reasoning tends to be called “strong AI,” in that any result can be used to not only build systems that think but also to explain how humans think as well. However, we have yet to see a real model of strong AI or systems that are actual simulations of human cognition, as this is a very difficult problem to solve. When that time comes, the researchers involved will certainly pop some champagne, toast the future and call it a day.

The work in the second camp, aimed at just getting systems to work, is usually called “weak AI” in that while we might be able to build systems that can behave like humans, the results will tell us nothing about how humans think. One of the prime examples of this is IBM’s Deep Blue, a system that was a master chess player, but certainly did not play in the same way that humans do.

Somewhere in the middle of strong and weak AI is a third camp (the “in-between”): systems that are informed or inspired by human reasoning. This tends to be where most of the more powerful work is happening today. These systems use human reasoning as a guide, but they are not driven by the goal to perfectly model it.

A good example of this is IBM Watson. Watson builds up evidence for the answers it finds by looking at thousands of pieces of text that give it a level of confidence in its conclusion. It combines the ability to recognize patterns in text with the very different ability to weigh the evidence that matching those patterns provides. Its development was guided by the observation that people are able to come to conclusions without having hard and fast rules and can, instead, build up collections of evidence. Just like people, Watson is able to notice patterns in text that provide a little bit of evidence and then add all that evidence up to get to an answer.

The important takeaway here is that in order for a system to be considered AI, it doesn’t have to work in the same way we do. It just needs to be smart. AI is the concept which is changing the market rapidly. Such types of workshops and guest lectures sessions are periodically held in Pimpri Chichwad Polytechnic which is the Top recruitment polytechnic college in pune.

Narrow AI vs. general AI :-

There is another distinction to be made here -- the difference between AI systems designed for specific tasks (often called “narrow AI”) and those few systems that are designed for the ability to reason in general (referred to as “general AI”). People sometimes get confused by this distinction, and consequently, mistakenly interpret specific results in a specific area as somehow scoping across all of intelligent behavior.

Systems that can recommend things to you based on your past behavior will be different from systems that can learn to recognize images from examples, which will also be different from systems that can make decisions based on the syntheses of evidence. They may all be examples of narrow AI in practice, but may not be generalizable to address all of the issues that an intelligent machine will have to deal with on its own. For example, I may not want the system that is brilliant at figuring out where the nearest gas station is to also perform my medical diagnostics.

The next step is to look at how these ideas play out in the different capabilities we expect to see in intelligent systems and how they interact in the emerging AI ecosystem of today. That is, what they do and how can they play together.

16. Domain Name System(DNS)


Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.

The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

Short for digital nervous system,a term coined by Bill Gates to describe a network of personal computers that make it easier to obtain and understand information.

In Pimpri Chinchwad Polytechnic in Computer Science Department gives full knowledge about Domain Name System in Network Management and Administration.

Domain Name System Architecture

The Domain name system comprises of Domain Names, Domain Name Space, Name Server that have been described below:

Domain Names

Domain Name is a symbolic string associated with an IP address. There are several domain names available; some of them are generic such as com, edu, gov, net etc, while some country level domain names such as au, in, za, us etc.

The following table shows the Generic Top-Level Domain names:

Domain Name Meaning
Com Commercial business
Edu Education
Gov U.S. government agency
Int International entity
Mil U.S. military
Net Networking organization
Org Non profit organization

The following table shows the Country top-level domain names:

Domain Name Meaning
au Australia
in India
cl Chile
fr France
us United States
uk United Kingdom
jp Japan
es Spain
de Germany
ca Canada
ee Estonia
hk Hong Kong

Domain Name Space

The domain name space refers a hierarchy in the internet naming structure. This hierarchy has multiple levels (from 0 to 127), with a root at the top. The following diagram shows the domain name space hierarchy:

LECTURE

In the above diagram each subtree represents a domain. Each domain can be partitioned into sub domains and these can be further partitioned and so on.

Name Server

Name server contains the DNS database. This database comprises of various names and their corresponding IP addresses. Since it is not possible for a single server to maintain entire DNS database, therefore, the information is distributed among many DNS servers.

  • Hierarchy of server is same as hierarchy of names.
  • The entire name space is divided into the zones

Zones

Zone is collection of nodes (sub domains) under the main domain. The server maintains a database called zone file for every zone.

LECTURE

If the domain is not further divided into sub domains then domain and zone refers to the same thing.

The information about the nodes in the sub domain is stored in the servers at the lower levels however; the original server keeps reference to these lower levels of servers.

Types of Name Servers

Following are the three categories of Name Servers that manages the entire Domain Name System:

  1. Root Server
  2. Primary Server
  3. Secondary Server

Root Server

Root Server is the top level server which consists of the entire DNS tree. It does not contain the information about domains but delegates the authority to the other server

Primary Servers

Primary Server stores a file about its zone. It has authority to create, maintain, and update the zone file.

Secondary Server

Secondary Server transfers complete information about a zone from another server which may be primary or secondary server. The secondary server does not have authority to create or update a zone file.

DNS Working

DNS translates the domain name into IP address automatically. Following steps will take you through the steps included in domain resolution process:

  • When we type www.tutorialspoint.com into the browser, it asks the local DNS Server for its IP address. Here the local DNS is at ISP end.
  • When the local DNS does not find the IP address of requested domain name, it forwards the request to the root DNS server and again enquires about IP address of it.
  • The root DNS server replies with delegation that I do not know the IP address of www.tutorialspoint.com but know the IP address of DNS Server.
  • The local DNS server then asks the com DNS Server the same question.
  • The com DNS Server replies the same that it does not know the IP address of www.tutorialspont.com but knows the address of tutorialspoint.com.
  • Then the local DNS asks the tutorialspoint.com DNS server the same question.
  • Then tutorialspoint.com DNS server replies with IP address of www.tutorialspoint.com.
  • Now, the local DNS sends the IP address of www.tutorialspoint.com to the computer that sends the request.

These sessions are conducted under Network Management and Administration Lecture in Pimpri Chinchwad Polytechnic which is one of the best college in Pune

18. Software Testing


Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not. Testing is executing a system in order to identify any gaps, errors, or missing requirements in contrary to the actual requirements. In today’s world automated testing plays a vital role. The different technologies developing in it has raised the bars of testing to great level. In Pimpri Chinchwad Polytechnic which is one of the best Polytechnic College in Computer Department it provides students full practical as well as theoretical knowledge about Testing. Various training programs are conducted for the students to get the practical knowledge of testing.

Who does Testing?

It depends on the process and the associated stakeholders of the project(s). In the IT industry, large companies have a team with responsibilities to evaluate the developed software in context of the given requirements. Moreover, developers also conduct testing which is called Unit Testing. In most cases, the following professionals are involved in testing a system within their respective capacities:

  • Software Tester
  • Software Developer
  • Project Lead/Manager
  • End User

Different companies have different designations for people who test the software on the basis of their experience and knowledge such as Software Tester, Software Quality Assurance Engineer, QA Analyst, etc.

When to Start Testing?

An early start to testing reduces the cost and time to rework and produce error-free software that is delivered to the client. However in Software Development Life Cycle (SDLC), testing can be started from the Requirements Gathering phase and continued till the deployment of the software. It also depends on the development model that is being used. For example, in the Waterfall model, formal testing is conducted in the testing phase; but in the incremental model, testing is performed at the end of every increment/iteration and the whole application is tested at the end.

Testing is done in different forms at every phase of SDLC:

  1. During the requirement gathering phase, the analysis and verification of requirements are also considered as testing.
  2. Reviewing the design in the design phase with the intent to improve the design is also considered as testing.
  3. Testing performed by a developer on completion of the code is also categorized as testing.

When to Stop Testing?

It is difficult to determine when to stop testing, as testing is a never-ending process and no one can claim that software is 100% tested. The following aspects are to be considered for stopping the testing process:

  1. Testing Deadlines
  2. Completion of test case execution
  3. Completion of functional and code coverage to a certain point
  4. Bug rate falls below a certain level and no high-priority bugs are identified
  5. Management decision

19. TECHNICAL EVENT (TECHLONS) “PAPER PRESENTATION"


The “Pimpri Chinchwad Education Trust” is composed group of highly active, devoted persons of high social standing. They have joined together to establish, develop and run a large technical and allied education institutes comprising various useful educational courses. This suburb being the largest Industrial area in Asia needed enormous technically skilled manpower.

With these dual objectives of public and industrial needs trust invited reputed citizens from this region to participate in this Local and National endeavour and established Pimpri Chinchwad Education Trust. The trust then introduced Diploma Courses in Engineering by starting the Pimpri Chinchwad Polytechnic College in Pune from the year 1990.

Pimpri Chinchwad Polytechnic is one of the Best dimploma colleges in Pune, which in the year 2015 celebrated its Silver Jubilee.

This institute consists of best Diploma engineering college, pacious buildings for various Engineering Departments, sports ground, canteen, and mess which are spread over large area of land under Pimpri Chinchwad New Town Development Authority popularly known as Pradhikaran. The plot has been developed into a beautiful landscape in the vicinity of Akurdi railway station.

At primpri chinchwad polytechnic they arrange technical event (TECHLONS) on 1st of September 2017, in this event “paper presentation” competition is arranged.so in that competition number of students have been participated from other colleges, there are 30 entries for this competition. Pimpri chinchwad polytechnic this college is very well plan and organize this event.

LECTURE

presentation is the process of presenting a topic to an audience. It is typically a demonstration, introduction, lecture, or speech meant to inform, persuade, or build good will.

The introduction is the most important part of your presentation as it sets the tone for the entire presentation. Its primary purpose is to capture the attention of the audience, usually within the first 15 seconds. 4-H Youth Development Programs|

20. BASICS OF INTERNET


The Internet is a global collection of computer networks that are linked together by devices called routers and use a common set of protocols for data transmission known as TCP/IP (transmission control protocol /Internet protocol).

LECTURE

To acquire basic knowledge about internet students can take admission in best polytechnic college in Pune. In Polytechnic, MSBTE Curriculum Information & communication Technology subject is present. This subject enables to create business document, perform data analysis & its graphical representation & making electronic slide show presentation.

What is the Internet?

The Internet is a global network of billions of computers and other electronic devices. With the Internet, it's possible to access almost any information, communicate with anyone else in the world, and do much more.

What is the Web?

The World Wide Web—usually called the Web for short—is a collection of different websites you can access through the Internet. A website is made up of related text, images, and other resources. Websites can resemble other forms of media—like newspaper articles or television programs—or they can be interactive in a way that's unique to computers.

How does the Internet work?

It's important to realize that the Internet is a global network of physical cables, which can include copper telephone wires, TV cables, and fiber optic cables. Even wireless connections like Wi-Fi and 3G/4G rely on these physical cables to access the Internet. When you visit a website, your computer sends a request over these wires to a server. A server is where websites are stored, and it works a lot like your computer's hard drive. Once the request arrives, the server retrieves the website and sends the correct data back to your computer.

Other things you can do on the Internet

One of the best features of the Internet is the ability to communicate almost instantly with anyone in the world. Email is one of the oldest and most universal ways to communicate and share information on the Internet, and billions of people use it. Social media allows people to connect in a variety of ways and build communities online. There are many other things you can do on the Internet. There are thousands of ways to keep up with news or shop for anything online. You can pay your bills, manage your bank accounts, meet new people, watch TV, or learn new skills. You can learn or do almost anything online.

 What is the World Wide Web (WWW)?

The WWW is a collection of Internet sites that can be accessed by using a hypertext interface. Hypertext documents on the web contain links to other documents located anywhere on the web. By clicking on a link, you are immediately taken to another file or site to access relevant materials. The interesting thing about Hypertext links is that the links might take you to related material on another computer located anywhere in the world, rather than just to a file on your local hard drive.

Basic WWW Concepts

1. BROWSER 

A WWW browser is software on your computer that allows you to access the World Wide Web. Examples include Netscape Navigator and Microsoft Internet Explorer. Please know that a browser can’t work its magic unless you are somehow connected to the Internet. At home, that is normally accomplished by using a modem that is attached to your computer and your phone line and allows you to connect to, or dial-up, an Internet Service Provider (ISP). At work, it may be accomplished by connecting your workplace’s local area network to the Internet by using a router and a high speed data line.

2. HYPERTEXT AND HYPERMEDIA –

Hypertext is text that contains electronic links to other text. In other words, if you click on hypertext it will take you to other related material. In addition, most WWW documents contain more than just text. They may include pictures, sounds, animations, and movies. Documents with links that contain more than just text are called hypermedia.

3. HTML (HYPERTEXT MARKUP LANGUAGE) –

HTML is a set of commands used to create world wide web documents. The commands allow the document creator to define the parts of the document. For example, you may have text marked as headings, paragraphs, bulleted text, footers, etc. There are also commands that let you import images, sounds, animations, and movies as well as commands that let you specify links to other documents. If you wanted to create your own web page, you would need to know HTML or be able to use a tool that can generate HTML such as Claris HomePage or Adobe PageMill.

4. URL (UNIFORM RESOURCE LOCATOR) –

Links between documents are achieved by using an addressing scheme. That is, in order to link to another document or item (sound, picture, movie), it must have an address. That address is called its URL. The URL identifies the host computer name, directory path, and file name of the item. It also identifies the protocol used to locate the item such as hypertext, ftp, telnet or news.

5. HTTP (HYPERTEXT TRANPORT PROTOCOL) –

HTTP is the protocol used to transfer hypertext or hypermedia documents.

6. HOME PAGE –

A home page is usually the starting point for locating information at a WWW site. Currently, the home page for Pimpri Chinchwad Polytechnic is http://www.pcpolytechnic.com/ which is best polytechnic college in pune.

7. CLIENTS AND SERVERS –

If a computer has a web browser installed, it is known as a client. A host computer that is capable of providing information to others is called a server. A server requires special software in order to provide web documents to others.

21. “Web Page Designing ….!!!”


HTML is the standard markup language for creating Web pages.

  • HTML stands for Hyper Text Markup Language
  • HTML describes the structure of Web pages using markup
  • HTML elements are the building blocks of HTML pages
  • HTML elements are represented by tags
  • HTML tags label pieces of content such as "heading", "paragraph", "table", and so on
  • Browsers do not display the HTML tags, but use them to render the content of the page
  • With HTML you can create your own Web site

A Simple HTML Document

<!DOCTYPE>

<HTML>

<head>

<title> Page Title </title>

</head>

<body>

<h1> My First Heading <h1>

<p> My first paragraph</p>

</body>

</html>

Output:-

My First Heading
My first paragraph.

HTML Tags

  • HTML tags normally come in pairs like <p> and </p>
  • The first tag in a pair is the start tag, the second tag is the end tag
  • The end tag is written like the start tag, but with a forward slash inserted before the tag name

Write HTML Using Notepad or TextEdit:

Web pages can be created and modified by using professional HTML editors.
However, for learning HTML we recommend a simple text editor like Notepad (PC) or TextEdit (Mac).We believe using a simple text editor is a good way to learn HTML.

Web Browsers

The purpose of a web browser (Chrome, IE, Firefox, Safari) is to read HTML documents and display them.The browser does not display the HTML tags, but uses them to determine how to display the document:

LECTURE
