Terminology In Computer

BIOS
Basic Input Output System. Software installed on a computer chip to manage basic operations such as screens, hard drives, memory, VGA, etc.. Part of the operating system that can identify the set of programs used to boot the computer, before placing the system diskette. Contained in the ROM BIOS (Read Only Memory) of the system and generally stored permanently. Programs that used a microprocessor to turn on the computer. The BIOS also manages data flow between computer operating systems and enhancements that are connected to the computer.

BUS
Channel consisting of a set of similar lines. A set of cables which is a transportation information to all equipment within the system. Such information may include data, command or address.

CHACE MEMORY
High-speed memory that is able to cooperate
with the CPU, acting as a buffer between the CPU and
slow main memory.

CASING
The box where the engine computer (motherboard and supporters, power supply, disk drives, hard drives, CD ROM drive). Container or place to protect the motherboard, the control board, power supply disk drives and other components kompenen. A computer case is actually nothing more than the framework of a computer. This case is where the components that make up a computer system is located, is also to put the cooling equipment (cooling fan), and also to electrical ground contained in the existing components through the frame is made of iron. Case is large with a expansion y ang many more preferably, with a lot of expansion space you can add other devices with ease. Examples of devices that can be added to this example, drive DVD, CD writer, and others. Currently tower case with a form are usually preferred over desktop case with a form due to having more space for expansion, and also can have a better cooling capability. A case can be either AT or ATX, where the difference lies in the future position of the motherboard, as well as power supply that came with the case. Case computer usually comes together with power supply, although sometimes it is suggested that you buy a separate power supply so it can get a second item with the same quality high.

CD ROM DRIVE
CD ROM player. A drive to record or play a Compact Disk, which is often found is a CD-ROM (CD Read Only Memory), MO (Magneto-optical) and WORM (Write Once Read Many).



CGA
Color Graphics Adapter (CGA) One type of monitor, ie Ibm standards for quality low-resolution monitors, in graphics mode can only display 4 colors.


CLOCK
Clock / timer. Frequency generator circuit. The main source of computer electronic pulses. Clock used to synchronize the operation of all elements of the computer.


CMOS
Compelementary Metal Oxide Semiconductor (CMOS) small-sized 64 bytes of RAM that stores the BIOS settings when the computer is turned off. CMOS is an extension of MOS technology to produce ICs with low battery power requirements. CMOS is used to store configuration programs, diagnostic programs and information on the date and time of files that can not be lost even if the computer is turned off.

CPU
Central Processing Unit (CPU), main processing unit in technical terms is called a microprocessor, is in general terms a computer is a machine that is the case with all of the contents therein. Central processing of inputs to produce outputs. T ermasuk here are all the registers, arithmetic circuits, comparator units, and so on.


CRT
Catoda Ray Tube (CRT) technology used to make the system display / computer monitors use cathode ray tubes.



DISK
A data storage media. What is meant by the disk is a floppy disk or hard disk large capacity data storage media. While the floppy disk is a floppy disk. The dish is coated with a thin magnetic material (iron oxide) that is able to store some data or information. The reading and writing information centered on the track.


DRAM
Dynamic RAM (DRAM) Memory PC-readable and writable. To store data in memory, it needs to refresh periodically. This memory type is widely used in the main memory that is used for routine process.


EGA
Enhanced Graphics Adapter (EGA) One of the standard monitor resolution. EGA could display 16 colors in the graph model, one level above the CGA monitor. EGA monitor with a card capable of displaying 16 colors in the form of text (80 x 25 characters or 40 x 25 characters), 16 colors in the form of low resolution and 4 colors in high resolution graphic display 640 x 350 dots. The development of this type of EGA include ATI Technologies Inc. with a card called EGA WONDER, can display 132 x 25 characters. Monitor type EGA monitor still uses the same connector type CGA monitor and Monochrome. Everex issued cards EPGA (Enhanced Professional Graphics Adapter), capable of displaying 649 x 480 dot (dot) with 256 colors, from basic color combinations 4096 (pallette). EPGA and is also called Pega (Professional Enhanced Graphics Adapter), or the PGA (Professional Graphics Adapter), text display 132 x 43 characters in the multi-frequency or jubilee sync, and the flexibility to use the monitor as well as enhanced monochrome monitor. This monitor uses 9-pin connector consisting of 2 lines.

HEAD
Head, the tip of the recorder, part of a drive or disk that functions to read or write.

DRIVE
Door, driver disk.

KEYBOARD
Key board, keyboards.






MOTHERBOARD
Computer circuit board where all the electronic components of computers strung.


PERIPHERAL
Specifications support equipment needed by a PC in order to work optimally.


PIC
Programmable Interrupt Controller (PIC) Full interrupted programmed. The chip that functions to control the insertion process between peripherals. Between the peripheral control devices that assist the CPU in the process of insertion.


VRAM
Video Random Access Memory (Video RAM) Type spesialdari DRAM which allows high speed direct memory access through the video circuit. This memory type is more expensive when compared to conventional DRAM chips.


POWER SUPPLY
An electronic circuit that serves as the power supply / donor source voltage / current to the equipment.
