Computer Glossary Set – 2

1. BANDWIDTH

Bandwidth refers to how much data you can send through a network or modem connection.

It is usually measured in bits per second, or “bps.”

2. BOOT LOADER

It reads the main portion of the operating system from secondary memory.

3. BATCH PROCESS

A batch process performs a list of commands in sequence.

It be run by a computer’s Operating system using a script or batch file, or may be executed within a program using a macro or internal scripting tool.

4. BAUD

Baud is used to measure the rate of electrical signals, or “signaling elements,” for modems, networks, serial cables, and other data transfer mediums.

5. BIO METRICS

Biometrics refers to technologies used to detect and recognize human physical characteristics.

Biometric authentication, a type of security authorization based on biometric input.

6. BLUETOOTH

Wireless technology enables communication between Bluetooth-compatible devices.

It is used for short-range connections between desktop and laptop computers, PDAs (like the Palm Pilot or Handspring Visor), digital cameras, scanners, cellular phones, and printers.

7. BIT TORRENT

BitTorrent is a peer-to-peer (P2P) file sharing protocol designed to reduce the bandwidth required to transfer files.

computers with the same file and begin downloading the file from several computers at once. Since most ISP’s offer much faster download speeds than upload speeds, downloading from multiple computers can significantly increase the file transfer rate.

8. BOTNET

A botnet is a number of Internet-connected devices used by a botnet owner to perform various tasks.

Botnets can be used to perform Distributed Denial Of Service Attack.Steal data, send spam, and allow the attacker access to the device and its connection.

9. BUG

A bug is an error in a software Program.It may cause a program to unexpectedly quit or behave in an unintended manner.

10. BYTE

A byte is a set of 8 bits that represent a single character in the computer’s memory.

Bits are often used to measure data transfer speeds, bytes are used to measure file sizes, hard disk space, and computer memory.

11. BUS

 A Bus is a communication system that transfers data between components inside a Computer, or between computers.

12.BRIDGE

It connects two or more local area networks (LANs) together.

The device is similar to a router, but it does not analyze the data being forwarded. Because of this, bridges are typically fast at transferring data, but not as versatile as a router.

13.  bps

“Bits Per Second.”  Bits per second is the standard way of measuring how fast data moves across a network or phone system.

14. BOOLEAN

This is the logic that computers use to determine if a statement is true or false. There are 4 main boolean operators: AND, NOT, OR, and XOR.

15. BITMAP

A bitmap is a map of dots, or bits (hence the name), that looks like a picture as long you are sitting a reasonable distance away from the screen.

Common bitmap file types include BMP , JPEG, GIF, PICT, PCX, and TIFF.
