LEARNING COMPUTER COMPONENTS BASIC & REPAIR ( 1 )

 

Computers are digital electronic devices that are designed in a modular fashion. The computer system is composed of a number of module components and tools that have the duties and functions of each and then linked together to form a computer system

Components of computer systems can be grouped according to the function of:
A. Processor unit
B. Bus unit
C. Storage devices
D. Device I / O
E. Inter device mukaspan

PROCESSOR UNIT

Processor Unit serves as the "brains" and "Body" of computer systems which process the instruction program, connect and manage data traffic on the entire system.
Components of the processor unit comprising:

 

1. Processor
2. Motherboard
3. Memory
4. Power Supply
5. Casing

Unit Processor> Processor
Processor or CPU (Central Processing Unit) is the brain of the computer that performs processing and arithmetic operations and logic of the instructions given to the computer program.

Processor chip is made of pure silicon chip containing the finger nails of the integrated circuit from thousands to millions of transistors that implement the functions of the processor. Processor circuit connected with the legs beneath the chip for signal communication lines into and out of circuit.
The performance of each type of processor and is influenced by the following factors:
Clock Speed
Wide registers / internal data bus
External data bus width
Capacity of the memory cache (L1 and L2)

Processor Unit> Motherboard
  Motherboard or main board is the largest circuit board in the computer and the "Agency" that connects all the units in the computer system.
Principal components on the motherboard consists of:
Socket / Slot processor
Chipset (Northbridge and Southbridge)
Super I / O Chip ROM BIOS
Socket memory (SIMM / DIMM / RIMM)
Bus Slot (Type ISA / PCI / AGP)
Voltage Regulator
CMOS batteries
