Every computer you see depend on some sort of hardware to complement the work of the software in it. today am going to share with you five important computer hardware.

today am going to share with you five important computer hardware.

  • RAM

Is the computer memory normally called main memory because it is this memory that holds our programs waiting to be executed by the CPU and it is this memory that our operating system is loaded on
The two forms main forms of RAM are are the static and dynamic RAM, both of them are considered to be volatile as their state is lost when power is removed from the system which means that they can only store data when the system is power on. static ram is more expensive to produce but is generally faster and required less power than dynamic ram.

It is also used to a cache memory for the CPU in modern computer systems, the dynamic ram uses a transistor and a capacitor pairs which together comprise a memory cell.

  • CENTRAL PROCESSING UNIT

This is called processor which is an electronic circuitry that works on a list of things to do called instructions and its work on a list of instructions called program, it is an important part of computer system, the CPU send signals to control another part of the computer, and the CPU is divided into the arithmetic logic unit and the control unit

  • THE MOTHERBOARD

Is the heart of the computer system every part of the computer relies on the motherboard to function effectively and it maintain the connection between every component of the computer and ensure that things are operating smoothly between them, the motherboard.

  • HARD DISK

Is a nonvolatile magnetic data storage device, it feature consist of rotating rigid platter on a motor-driven spindle within a protective enclosure, hard disk drives have been dominant device for secondary storage of data in general purpose computer since the 1960s, they have maintained this position because of their advancement in reading density, hard disk operate on a high-speed serial interface.

  • POWER SUPPLY UNIT

This supplies direct current (DC) to all other parts of the computer system, it provides different range d.c voltage like 12v,3v,5v and -12v for use by the different component of the computer system, the power supply is of two type namely AT and ATX power supply.
