COMPUTER NETWORKING

Detailed explanation-1: -Information transmitted through internet is broken down in terms of small units of data called packets and are routed through a network based on the destination address contained within each packet. Breaking communication down into packets allows the same data path to be shared among many users in the network.

Detailed explanation-2: -Why use packets? Packets are used for efficient and reliable transmission of data. Instead of transferring a huge file as a single data block, sending it in smaller packets improves transmission rates. Packets also enable multiple computers to share the same connection.

Detailed explanation-3: -Each time one device sends a file to another, it breaks the file down into packets so that it can determine the most efficient route for sending the data across the network at that time. The network devices can then route the packets to the destination where the receiving device reassembles them for use.
