bandwidth is the amount of data thatan be sent over a period of time, it is usually measured in bps
bps means bits per second
bandwidth can be used in many real life examples, eg a motorway: the wider the motorway gets, the more cars can go down it
bandwidth is very simple to understand, it just means the amount of data that can be sent over a period of time, and it is measured in bps, thats basically it (:
