highly useful for internet users!!

Speed or bandwidth of Internet is calculated as kilobits per second (kbps)
which is different from kilobytes per second
8 kilobits per second (SPEED) = 1 kilobytes per second (Transfer Rate/Download Rate)
For Example:
if your internet speed is 256kbps, then its transfer rate would be (256/8) = 32kbps
Some of the Important Terms used in Internet

Network = Interconnection of two or more computers

Load = demand on a network

Bandwidth = The Amount of Data that can be transmitted over a given segment of communication media within a specific time.
