Answer 1

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.

1. All computers on the Internet, communicate with one another using TCP/IP, which is a basic protocol of the Internet.
    
2.  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.
    
3. 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:

 

1. 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.
    
2. 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.
