Bandwidth

also called “data transfer rate,” the amount of data that can be carried online from one point to another in a given time period, usually expressed in bits (of data) per second (bps) or bytes per second (Bps). Dial-up Internet accounts, which use a standard telephone line to connect to an Internet Service Provider (ISP), have a very narrow bandwidth (about 50 Kbps or 50,000 bits per second) and take a long time to download data. A broadband Internet account can move data at anywhere from 128 Kbps to 2,000 Kbps or more and can download large files, such as video files, much faster.
