What is Bandwidth in Computer Network?

Bandwidth in networking refers to the maximum rate of data transfer across a given path that is indicating the capacity of the network to transmit data. It is commonly measured in bits per second (bps) and is not a measure of network speed; but rather the volume of data that can be transmitted in a certain time period.

What is Bandwidth

Bandwidth is analogous to the volume of water that can flow through a pipe; the wider the pipe’s diameter, the more water can flow through it at one time, similar to how higher bandwidth allows more data to flow through a network per second. Bandwidth is often mistaken for internet speed, but it actually represents the amount of information received every second, while speed refers to how fast that information is received or downloaded.
