Bandwidth -- the speed at which data is being transported. Usually specified in bits per second (bps). 128k (128,000 bps) and T1 (1.544Mbps) are examples of a bandwidth.

Binary -- a coding system consisting of ones and zeros that is used in the transport of data. Bit or Binary Digit -- the basic unit of data transport. A one or a zero represents each bit. This is the smallest unit of computerized data.

Bookmark - a feature of most web browsers that allows a computer user to save frequently accessed links to web sites in a file, rather than having to look up the URL or web site address each time.
