Back-end
Back-end refers to the part of an application that performs an essential task not apparent to the user.
Backward compatible
If software is backward compatible, it is compatible with earlier (superseded) versions of the same software. For example, the Microsoft word-processing program Word 2010 can read files created in the 2003 version of the same program, so it is backward compatible.
Bandwidth
Bandwidth refers to the maximum amount of data that can travel a communications path in a given time, usually measured in seconds.
Bit
A bit (short for binary digit) is the smallest unit of measurement in computing. 8 bits make up 1 byte.

Bookmark
A bookmark is a saved link to a particular Web page. Microsoft Internet Explorer denotes bookmarks as "favourites."
Boolean operators
Most search engines (e.g. Google) allow you to limit your search or make it more specific by using words such as "and", "or" and "not". These words are known as boolean operators because of their origin as terms in logic.
Boot (re-boot)
To boot (or re-boot) is to load and initialise the operating system on a computer. Think of it as starting up your computer. In Windows you can use the key combination CTRL and ALT and DEL as a "soft" boot. This means restarting the computer rather than turning it completely off and on again, which could cause damage to your computer's hard disk under some circumstances.
Bounce back
An email message that cannot be delivered and returns an error notification to the sender is said to "bounce back". If you receive such an error notification, check that you have typed the address correctly.
Broadband
Broadband is a type of communications technology whereby a single wire can carry more than one type of signal at once; for example, audio and video. Cable TV is one technology that uses broadband data transmission.
