2. A SIMM, or single in-line memory module, is a type of memory module containing random-access memory used in computers from the early 1980s to the late 1990s.It has either 30 pins or 72 pins.


*******

3. CMOS RAM is a volatile, low-power complementary metal-oxide-semiconductor. It is alternatively referred to as Real Time Clock.


*******

4. A thin-film-transistor or TFT is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast.


*******

5. Winchester Drive is the another term for hard disk drive. The term Winchester comes from an early type of disk drive developed by IBM that had 30MB of fixed storage and 30MB of removable storage.


*******

6. PCI stands for Peripheral Component Interconnect. It is a local computer bus for attaching hardware devices in a computer. The first version of conventional PCI found in consumer desktop computers was a 32-bit bus using a 33 MHz bus clock .


*******

7. A Video Graphics Array or VGA connector is a three-row 15-pin connector.VGA connectors and cables carry analog component of video signals, and VESA Display Data Channel (VESA DDC) data.


*******

8. DVI is a video display interface. It was developed to be an industry standard for transmitting digital video content to display devices at resolutions as high as 2560 x 1600.


*******

9. FRU stands for Field Replaceable Unit. It is a printed circuit board that can be quickly and easily removed from a computer and replaced by the user or a technician without having to send the entire product or system to a repair facility.


*******

10. ATX is the most common motherboard design. An ATX power supply provides a number of peripheral power connectors and two connectors for the motherboard in the modern systems.


*******

11. Devomark is a Latin type Keyboard. Colemak is a modern alternative to the QWERTY and Dvorak layouts, designed for efficient and ergonomic touch typing in English.


*******

12. System Request is a key on personal computer keyboard. It has no standard use. It was Introduced by IBM with the PC/AT. It was intended to be available as a special key to directly invoke low-level operating system functions.


*******

13. A cathode ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface. Most desktop computer displays make use of CRTs.


*******

14. Impact printer refers to printers that work by banging a head or needle against an ink ribbon to make a mark on the paper. This includes dot-matrix printers, daisy-wheel printers, and line printers.


*******

15. There are two main types of plotters – drum and flatbed plotters. Drum plotters spin the paper back and forth on a cylindrical drum while the ink pens move left and right. The drum plotters are generally smaller than flatbed plotters.


*******

16. Pen Drive is also known as a USB flash drive, thumb drive, pen drive, gig stick, flash stick, jump drive, disk key. It is a data storage device that includes flash memory with an integrated USB interface. It is typically removable, rewritable and much smaller than an optical disc.


*******

17. EIDE was developed by Western Digital and an interface used on IBM compatible computers. EIDE supports data rates from 4 and 16.6 MBps.


*******

18. LGA is a chip package with a very high density of contacts. LGAs differ from traditional chips with protruding pins that are inserted into a socket. An LGA chip has flat pads on the bottom of its package that touch contacts on the motherboard socket.


*******

19. The recent Pentium entries are Pentium III and Pentium 4.Pentium 4 are smaller than Pentium Iain Pentium III, the bus speed is generally 133 MHz while the bus speed in Pentium 4 is at least 400MHz.


*******

20. Computer hardware includes the physical, tangible components of a computer system .It includes CPU, Cabinet, Graphic Card, Sound Card, Motherboard, Speaker, Keyboard, Mouse, Desktop etc.
