Sun, 12 Jun 2022 16:52:16 +0000

Ans. 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. In fact, it is a set of protocols, i.e. TCP and IP.

TCP is a protocol, which is responsible for finding a path to 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 paths toward the destination. The TCP makes sure that the datagram arrives at the destination correctly.

IP (Internet Protocol): It is 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.

Answer selected: Write a detailed note on working of Internet.

Sun, 12 Jun 2022 16:43:14 +0000

Ans. 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 addresses part, i.e. addresses of destination and source up to 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 checks this address to see where to forward the message.

Answered: How did the Internet begin?

Sun, 12 Jun 2022 16:15:26 +0000

Ans. 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 the 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 the mid-’80s 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 organizations and people started working to build their own networks, named private networks, which were later (in the 1990s) connected with ARPANET and NSFnet to form the Internet.
The Internet really became popular in the 1990s after the development of World Wide Web (WWW).

Answered: What is DNS and also explain its functions?

Sun, 12 Jun 2022 14:44:33 +0000

It associates various information with domain names assigned to each of the participating entities.

The different functions of DNS are as follows:

It translates meaningful domain names into numerical IP addresses, which is needed for the purpose of locating computer services and devices worldwide.
It serves as the phone book for the Internet by translating human-friendly computer host names into IP addresses.
The DNS can be quickly updated, allowing a service’s location on the network to change without affecting the end-users.
It distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative names servers for each domain.
It also specifies the technical functionality of the database service. It defines the DNS protocol, a detailed specification of the data structure and data communication exchanges used in DNS, as part of the Internet Protocol Suite (IPS).

Answer selected: Why is Internet called ‘Network of Networks’?

Sun, 12 Jun 2022 11:56:04 +0000

Ans. Internet is called the ‘Network of Networks’ because it is a 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 smaller heterogeneous computer networks.
The network which consists of thousands of networks spanning the entire globe is known as "The Internet".
The Internet is a worldwide collection of networked computers, which are able to exchange information with each other very quickly. Most people use the Internet in two ways, E-mail, and World Wide Web.
On 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 a central interconnecting structure that connects one or more networks.
