Main components of Typical Computer
Types of Computer
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).
