MAIN COMPONENTS OF A TYPICAL

COMPUTER

Central Processing Unit (CPU)

The microprocessor “brain” of the computer system. Everything that a computer does is overseen by the CPU.

Memory

This is very fast storage used to hold data. Specific types of Memory in the computer:Random-access memory (RAM)Read-only memory (ROM)Basic input/output system (BIOS)CachingVirtual memory

Motherboard

This is the main circuit board that all of the other internal components connect to; the “Heart of the computer”.

Power Supply

An electrical transformer

Regulates the electricityused by the computer

Hard Disk

This is large-capacity permanent

storage used to hold information such as programs and documents.

Operating System

This is the basic software that allows the user to interface with the computer.

Integrated Drive Electronic (IDE)

Controller This is the primary

interface for the hard drive, CD-ROM and floppy disk drive.

Peripheral Component Interconnect (PCI) Bus

The most common way to connect additional components to the computer, PCI uses a series of slots on the motherboard that PCI cards plug into.

SCSI “scuzzy”

The small computer system interface is a method of adding additional devices, such as hard drivers or scanners, to the computer.

Advanced or Accelerated Graphic Port (AGP)

Is a very high-speed connection used by

the graphic card to interface with the computer.

Sound Card

This is used by the computer to record and play audio by converting analog sound into digital information and back again.

Graphic Card or Video Card

This translates images data from the computer into a format that can be displayed by the monitor.

TYPES OF COMPUTERS

Digital ComputerDigital refers to the processes in computers that

manipulate binary numbers (0s or

1s), which represent

switches that are turned on or off

by electrical current. A bit can have the value 0 or value 1, but

nothing in between 0 & 1.

Analog ComputerAnalog refers to

circuits or numerical

values that have a

continues range. Both 0

& 1 can be represented by

analog computers, but so can 0.5, 1.5 or a number

like ∏ (approximately

3.14).
