BIRTH OF YOUR COMPUTER AND WHY IT'S CALLED A COMPUTER

The computer as the name it computes a program to find instruction in it for execution.
The main component on a computer is a processor ,the processor understand 0s and 1s.
The reason why it understands 0s and 1s because its self is in 0s and 1s
0 represent current not flowing and 1 represent current flowing.

The processor is made from transistors a three terminal device with Base(b), collector(c) and emmiter(E) the transistor what it does is switching in 0s and 1s ,0 when off and 1,when on.
This is achieved by building logical gates out of transistor namely AND,OR,XOR etc which nomally evaluate true or false.

Intel core 4004 contain 1000 transistors now the latest processor contains about 30million transistor, this is achieved through lithilogy a very complicated process.
Engineers at intel developed very small transistors to fit in a small processor.
It is made for silcon got from tipical sand.

Transistors make micro controllers, microprocessors and all Integrated circuits  (ICs) in phones,tablets, computers etc.
After a complicated intergration of transistor ,the CPU must produce 2.6ghz freq to run a program.

The mother board componets work hand in hand with the CPU. These are given addresses like harddisks'rom,ram
A program can request the processor to get an image at address of hard disc in folder xxp,
The CPU contains registers like r0,r4,r5 etc,each with specific tasks to perform on your program like r0 to load variables in the memory.
The size of the registers determine the power and speed of processor ,r0-r16 in ARM processor is 32 bits making 32 bit processor which u call Pentium 4.

Thanks for reading I will explain more later. Have a great day.
