block of data is known as blocking and the number of records put together in each
block is called blocking factor.
Boolean algebra: An algebra that deals with logical propositions, which are either
true or false. This algebra is suitable for use with binary number system and is
very useful in designing logic circuits used by the processors of computer systems. Boolean function: A mathematical function in Boolean algebra. For example, w =
x + y • z.
Boolean variable: A variable used in Boolean algebra. It can assume a value true
Booting: The process of automatic loading of the operating system to primary
storage and readying a computer system for use.
Branch instruction: An instruction that transfers program control to a nonconsecutive instruction.
Bridge: An internetworking tool that is used to connect networks that use the same
communication protocols above the data-link layer but may or may not use the
same protocols at the physical and data-link layers.
Broadband channel: Communication channels that are capable of data transfer
rates of 1 million baud (bits/second) or more. They are used to handle high
volumes of data and for high-speed computer-to-computer communication or for
simultaneous transmission of data to several different devices.
Browser: A software tool that provides several navigation facilities to help users
do Internet surfing easily and effectively.
Buffer: A small storage area used to store information on a temporary basis for
compensating the difference in rates of flow of data between various computer
devices. For example, when data flows from an I/O device to the CPU, it passes
through a buffer.
Bug: An error in a computer program.
Built-in-functions: Subprograms which are provided with the language so that the
programmer need only call them in a program to have them automatically
invoked. Also known as intrinsic subprograms.
Bulletin Board System (BBS): The electronic counterpart of a wall-mounted
bulletin board that allows users of a computer network to exchange information
(by posting or reading message...
