5 MOST INPORTANT COMPUTER HARDWARE

  • RAM
               Is the computer memory normally called main memory because it is this memory that hold our programs waiting to be executed by the CPU and it is on this memory that our operating system is loading.
      The two forms  main forms of RAM are are the static and dynamic RAM, both of them are consider to be voilatile 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 produre but is generally faster and required less power than dynamic ram,it is also used to 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 work 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 other 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 connection between every component of the computer and ensure that things are operating smoothly between them, the motherboard.
  • HARD DISK
                Is a non volatile 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 1960s, they have maintain 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 part of the computer system, it provide different range d.c voltage like 12v,3v,5v and -12v for use by different component of the computer system, the power supply is of two type namely AT and ATX power supply.
