Bandwidth describes the amount of data which can be transmitted via a network connection, usually measured in bits per second.
Transfers data in both directions.
Binary number system
A system in which numbers are represented using only the digits 0 and 1.
A single unit of binary data.
The number of bits used to represent each pixel.
A representation of image data where each bit corresponds to an individual pixel on the screen.

Bluetooth is a wireless networking protocol which allows devices to connect together to provide services like Internet access, printing and data transfer without the intervention of the user.
Two-state algebra developed by George Boole.

Software used to render HTML pages.
Bubble Jet Printer
Operates by heating the ink until it forms a vapourised bubble which is then squirted as a tiny droplet of ink onto a page.
A part of memory used to hold data when communicating with a peripheral. Used when a fast acting part of the system (CPU) is exchanging data with a slow acting device (printer).
Each device on the network is directly connected to a single communications line.
Eight units of binary data (bits).
Testing of software outside the development organisation using clients or selected members of the public.
A method of program reﬁnement that starts with individual modules and builds them up into a complete program.
Running a program with test data that represents the extreme upper and lower values.
Within this range the program should operate normally.
A bug is a program error.
