Hardware of a computer (edited uncompleted version)

in this post i will be talking about the hardware of a computer what they do what they are for and such things...

the very most important part of hardware in the computer is the CPU(central processing unit) now every computer system unit contains at least one chip known as the microprocessor or CPU attached on the motherboard the mother board contains all the important chips that makes the computer operate.

All the actual and serious processing is done in the CPU also known as the microprocessor..the CPU in small computers such as laptops usually contains only one microprocessor.. on other computers such as the supercomputer may have more then one CPU that contains lots of different chips and micro chips to help it work and the software in these kind of computer are a subject to the CPU and how strong their CPU is such as the IBM company that used INTEL processors for their computers on the other side macintosh used motorola processors for their pc's and so on...

there are 3 main parts for the CPU:
1.the ALU (Arithmetic logical unit)
2.Registers
3.control unit

1.ALU:
it is the part in the CPU where all the mathematic and logical operations is done it does the four basic math operations division,addition,subtraction and multiplication Example:

A= 10 + 5 / B

the logical operations is what makes the pc (your pc or any pc) makes decisions on what to do if a certain thing happened and how to respond to it here is an example :

if 50 + 50 = 100 PRINT ("pass")

got it? good lets move on :P

2.regiters :
registers or immediate access memory where all the data used by the ALU and the program instructions and which are used by the control unit are stored

3.control unit :
tells the rest of the computer system how to carry out a program's instructions it also directs all the all the data flaw and electronic signals between the main memory and the arithmetic unit it also directs these signals between the main memory and input and output devices

i'll continue this in a few hours then repost it :)
