Packet : A packet is a small segment of a larger message. Data sent over computer networks, such as the Internet, is divided into packets. These packets are then recombined by the computer or device that receives them.

 

Bandwidth : Bandwidth specifically refers to the capacity at which a network can transmit data. For example, if the bandwidth of a network is 40 Mbps, it implies that the network cannnot transmit data faster than 40 Mbps in any given case.
