Backbone
A high-speed line or series of connections that forms a major pathway within a network. The term is relative, as a backbone in a small network will likely be much smaller than many non-backbone lines in a large network.
Bandwidth
How much data can be transmitted in a time period over a communications channel, often expressed in kilobits per second (kbps).
Baud
Unit of signaling speed equal to the number of discrete signal elements transmited per second. Baud is synonymous with bits per second (bps). In common usage the baud rate of a modem is how many bits it can send or receive per second. Technically, baud is the number of times per second that the carrier signal shifts value - for example a 1200 bit-per-second modem actually runs at 300 baud, but it moves 4 bits per baud (4 x 300 = 1200 bits per second).
BBS
(Bulletin Board System) - A computerized meeting and announcement system that allows people to carry on discussions, upload and download files, and make announcements without the people being connected to the computer at the same time. There are many thousands (millions?) of BBS's around the world, most are very small, running on a single IBM clone PC with 1 or 2 phone lines. Some are very large and the line between a BBS and a system like CompuServe gets crossed at some point, but it is not clearly drawn.
Binary
Data represented in binary format uses only two digits - 0 and 1.
Bit
A single digit number in base-2, in other words, either a 1 or a zero. The smallest unit of computerized data. Bandwidth is usually measured in bits-per-second.
Bps
(Bits-Per-Second) - A measurement of how fast data is moved from one place to another. A 28.8 modem can move 28,800 bits per second.
Browser
Client software that is used to look at various kinds of Internet resources. Examples include Microsoft's Internet Explorer and Netscape's Navigator.
Burstable Bandwidth
A hosting option that allows sites to use the available network capacity to handle periods of peak usage.
Business Hosting
Web hosting geared towards the mission-critical functions demanded by business-class customers.
Byte
A set of Bits that represent a single character. Usually there are 8 Bits in a Byte, sometimes more, depending on how the measurement is being made.
