Packets are the small blocks of data that are created by dividing a large block of data before transmission over a network.
Step-by-step explanation:
Packets are the small blocks of data that are created by dividing a large block of data before transmission over a network.
When data is transmitted over a network, it is divided into smaller units called packets. Each packet contains a portion of the original data, along with information such as the destination address and sequence number.
These packets are then sent individually over the network and reassembled at the destination to recreate the original data.
