B

1. Band Width

The bandwidth is basically the maximum speed at which data can be transmitted between computers in a network.

2. Batch File

A Batch file is a set of DOS commands contained within a single Text File. If this text has a file suffix of .BAT then by entering the file name at the DOS Prompt, The DOS commands will be executed one after the other. AUTOEXEC.bat is an example of a Batch File.

3. Baseband

The transmission of a signal without modulation. In a LAN, this implies that the whole medium is used to carry one signal at a time.

4. Baud

Unit  for  measuring   data  transmission   speed  of  a carrier.        Generally,   a baud  is identical  to bits  per  second(bps).

5. BASIC (Beginners All-Purpose      Symbolic     Instruction      Code)

An    easy-to-learn,     high-level,     interactive programming         language    that    is   used    frequently    with personal  computers,  and in time sharing  environments.

6. Bernoulli disk

A magnetic  disk-based  storage  medium  in which  a  single  hard   disk  platter   is  encased in  a  plastic cartridge.

7.  Beta Testing

Use of beta version of software by a selected group of users for identifying errors that might have been overlooked during regular testing phase.

8. Beta version

It is the version of software that is released to a selected group of users for testing before its actual release.

9. BCD (Binary Code Decimal)

One of the early coding system that is based on the the idea of converting each digit of a decimal number into its binary equivalent, rather than converting the entire decimal value into a binary form.

10.  BSNL

Bharat Sanchar Nigam Limited

11. Bitmap

A bit map defines a display space and the color for each pixel or “bit” in the display space. A Graphics Interchange Format and a JPEG are examples of graphic image file types that contain bit maps.

12.  Booting

Process of automatic loading of operating system to primary storage, and readying a computer system for use.

13. Bug

An error in a computer program that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.

14. BIOS

It is the basic program used as an interface between the operating system and the motherboard. The BIOS is stored in the ROM and cannot be rewritten. When the computer is switched on , it needs instructions to start. BIOS contain the instructions for the starting up of computer, The BIOS runs when the computer is switched on . It performs a Power On Self Test (POS) that checks that the hardware is functioning properly and the hardware devices are present.

15. Bit Operating System

This refers to an operating system which is capable of processing 16 bits (or bytes) at any one time. Windows 3.1 is an example. File names can be no more than 8 characters in 16 bit operating systems.

  • 286

The 80286 microprocessor was introduced by Intel in 1982. PC’s with this kind of microprocessor are normally referred to as 286 computers.

  • 32 Bit Operating System

This refers to an operating systems, which is capable of processing 32 bits (or 4 bytes) at any one time. Windows 95 is a Bit Operating System. One of the features that this allows is long file names.

  • 386

The 80386 microprocessor was introduced by Intel in 1985. PC’s with this kind of microprocessor are normally referred to as 386 computers.

  • 486

The 80486 microprocessor was introduced by Intel in 1989. PC’s with this kind of microprocessor are normally referred to as 486 computers.

  • 8086

The 8086 microprocessor was introduced by Intel in 1978.

  • 8088

The 8088 microprocessor was introduced by Intel 1978.

16. Boot

Quite simply to start up or restart (re-boot) the PC. When the PC is switches on the files which run the operating systems are executed.

17. Boot Disk

A floppy disk which contains the necessary files for an operating system which when processed will start up or “Boot” the PC. The floppy disk is inserted into the Floppy disk drive and the PC switched on.

18. Bus

Data is transmitted to and from the different components of a PC via a bus. Different types of BUS are –

  • CPU/Memory bus
  • I/O bus
  • Local Bus

The CPU/Memory bus runs at the same speed as the Processor but the I/O Bus runs at about 8 MHz.

19.  Bus Clock Speed

The speed in Megahertz at which the I/O bus runs.

20. Bus Mouse

A mouse that is attached to the BUS not via a serial port but through a special card attached to the mother board.
