communication exchanges used in DNS, as part of the Internet Protocol Suite (IPS).
Question: Why is Internet called ‘Network of Networks’?
Answer: Internet is called ‘Network of Networks’ because it is global network of computers that are linked together by cables and telephone lines making communication possible among them. It can be defined as a global network over a million of smaller heterogeneous computer networks. The network which consists of thousands of networks spanning the entire globe is known as Internet.
The Internet is a world wide collection of networked computers, which are able to exchange information with each other very quickly.
Mostly people use the Internet in two ways, E-mail and World Wide Web. In Internet, most computers are not connected directly, they are connected to smaller networks, which in turn are connected through gateways to the Internet backbone. A gateway is a device that
connects dissimilar networks. A backbone is central
interconnecting structure that connects one or more
networks.

Question: Write a detailed note on working of Internet.
Answer: The computers on the Internet are connected to each other through small networks. These networks are connected through the gateways to the Internet backbone.
All computers on the Internet, communicate with one another using TCP/IP, which is a basic protocol of the Internet.
TCP/IP (Transmission Control Protocol/Internet Protocol) manages the transmission of data/file/document on the Internet by breaking the data/file/document into small pieces or parts called packets or datagrams.
Each packet contains actual data and address part, i.e. addresses of destination and source upto 1500 characters.
Functioning of TCP and IP are as follows TCP It breaks message into smaller packets that are transmitted over the Internet and also reassembles these smaller packets into the original message that are received from the Internet.
IP It handles the address part of each packet, so that the data is sent to the correct address. Each gateway on the network check this address to see where to forward the message.
Question: How did the Internet begin?
Answer: In 1969, the University of California at Los Angeles and the University of Utah were connected with the beginning of the ARPANET (Advanced Research Projects Agency NETwork) using 56 kbit/s circuits,which is sponsored by U.S. (United States) Department of Defense (DoD). The goal of this project was to connect computers at different Universities and U.S. defense.
In mid 80’s another federal agency, the National Science Foundation (NSF) created a new high capacity network called NSFnet (National Science Foundation network),which was more capable than ARPANET. The only drawback of NSFnet was that it allowed only academic research on its network and not any kind of private business on it.
Now, several private organisations and people started working to build their own networks, named private networks, which were later (in 1990’s) connected with ARPANET and NSFnet to form the Internet. The Internet really became popular in 1990’s after the development of World Wide Web (WWW).
Question: Based on the paragraph, answer the questions thatfollow.
WWW was introduced on 13th March, 1989 by Tim Berners-Lee. It is a system of Internet servers that supports hypertext and multimedia to access several Internet protocols on a single interface. It is often abbreviated as the web or WWW or W3. It is a way of exchanging information between computers on the Internet, trying to tie them together into a vast collection of interactive multimedia resources. It is only a portion of what makes up the Internet, but it is the fastest growing part of the Internet.
The web lets people, organisations and companies publish information for other people to see. This makes the web a very useful tool for finding information about any topic.

(iii) WWW provides various attributes, which are as follows
(a) User-friendly The WWW resource works smoothly with most web browsers, such as Internet Explorer, Firefox etc.
(b) Multimedia documents WWW allows users to create and display web pages that contains various graphics, audio, video, animation and text.
(c) Interactive WWW provides interactivity using hyperlinks and input boxes (i.e. textboxes and checkboxes).
Question: Which protocol is the communication protocol for the Internet? Also, explain this protocol.
Answer: TCP/IP is the communication protocol for the Internet.
It defines the rules, computers must follow to communicate with each other over the Internet. The TCP/IP is a protocol used with E-mail transmission.
Infact, it is a set of protocol, i.e. TCP and IP.
TCP is a protocol, which is responsible for finding path for the destination. It also splits the message into several datagrams, if it does not fit in one datagram. Therefore,these datagrams are sent through different alternate pathstowards the destination. The TCP makes sure that the datagram arrives at the destination correctly.
IP (Internet Protocol) used by the Internet for transferring messages from one machine to another. The messages are sent in the form of packets. IP defines the packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination format.
Question: Read the following paragraph. Find six network and communication related abbreviations and give their expanded form alongwith a single-line definition of each of them.
The RBI is planning to expand its connectivity with all major banks of India. The plan includes providing TCP connectivity through HTTP for easy access points and seeks help from some ISPs to join hands in this venture.
Also, there is a plan to set-up IIS and SMTP servers. Some banks will go for ADSL line while others will use leased line connectivity to access these services.
The RBI is also taking help of IIT professors in this venture.
Answer: Six network and communication related abbreviations are as follows
(i) TCP (Transmission Control Protocol) A protocol developed for the Internet to get information from one network device to another.
(ii) HTTP (HyperText Transfer Protocol) A protocol that transmits hypertext over networks. This is the protocol of the web.
(iii) ISP (Internet Service Provider) An organisation that provides access to the Internet through various connectivity methods.
(iv) IIS (Internet Information Server) It is a Microsoft proprietary web server software.
(v) SMTP (Simple Mail Transfer Protocol) It distributes E-mail messages and attached files to one or more electronic mail boxes.
