Some Other Internal Parts Of CPU

In hardware we already discus two things Motherboard and Hard disk. Now we are discus three more parts which is also most important parts of Internal CPU.


1. RAM(Memory) :- 


Random Access Memory which is the computer memory that can be accessed randomly. RAM is the part which is used by computer and other device like printer also. There is two type of RAM (i) DRAM  (Dynamic Random Access Memory) (ii) SRAM (Static Random Access Memory)The two type in the technology they use to hold data, with DRAM being the more common type. In terms of speed, SRAM is faster. DRAM to be refreshed thousands of times per seconds while SRAM does not need to be refreshed, which is what makes in faster than DRAM. DRAM supports access times of about 60 nanoseconds, SRAM can give access times as low as 10 nanoseconds. Despite SRAM being faster, it's not as commonly used as DRAM because it's so much more expensive. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off.

2. PROCESSOR :-

The processor (CPU, for Central Processing Unit) is the computer's brain. It allows the processing of numeric data, meaning information entered in binary form (0 and 1), and the execution of instructions stored in memory.

In the hole computer the most important part is CPU. The CPU divides some different parts there are :-
1. Motherboard
2. Hard disk
3. Memory (RAM)
4. Power Supply
5. Processes
both are the main part in computer.


MOTHERBOARD:-
                            
motherboard, also known as a logic board or system board, is the most important circuit board that makes up a complex electronic system, or, a modern computer. It contains BIOS, Memory (RAM), mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset.

Basic Computer Parts and Uses with Photos

A computer is an electronic device, which executes software programs. It consists of 2 parts-hardware and software . Computer is very Important in today’s world. Millions of people use computers all over the world. We are Basically here for providing the solution of  Hardware Problems every one face in daily life and spend lot of money on them.we will help you to become a computer hardware specialist.So you can earn a huge money from it.
At the beginning we want to let you know the basic parts of a General Computer

MONITOR:- A monitor or display  is an electronic visual display for computers. The display device in older is CRT ( Cathode Ray tube ) now modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube about as deep as the screen size.Originally computer monitors were used for data processing and television receivers for entertainment; increasingly computers are being used both for data processing and entertainment. 

SYSTEM UNIT OR CPU:- CPU or Central Process Unit which is the most important unit in Computer. CPU (a microprocessor chip)  does most of the data processing the CPU and the memory form the central part of a computer . It consist the important hardware devices like Hard disk, Ram, Motherboard, Processor, CPU Fan etc.

KEYBOARD :- Keyboard is the Input part which is the used to add or input data. In keyboard have some Function keys (F1 to F12), control, alt, and all necessary keys.
