Q25. Explain the working of the Internet.
Ans. The computers on the Internet are connected to each other with the help of various small networks. These networks are in turn connected through the gateways to the Internet backbone. There are various steps for transmitting data or information through the Internet.
These steps are described below:
- The source computer (the computer that is sending the data)
prepares the data to send to the destination computer (the computer that receives the sent data) by dividing the data into small portions known as packets. Each packet is given a serial number, such as I, II, III, and so on.
- The packets are sent to the destination computer in a random order.
- The packets are reassembled in the order of their serial numbers and the original data is obtained at the destination computer.
