We all know that computers are complex machines made from a mixture of machine parts and electronic components. But the computer components that are used for operating the computer? The modern PC is still fully functional, without Bluetooth or a floppy drive. Here is a list of computer components of a computer system can not do without.



The motherboard is the basic unit of any computer system. This is the component of the computer for all other components of the computer are connected. It links together all the other important components of a computer system. Therefore, the motherboard sometimes the "heart" of a computer system are called.

The AC adapter or power supply has all the components of the computer with the power. It converts the voltage from a power outlet at lower voltages that are safe for the components inside the computer. Without a feeder, a computer and its components may not be able to live.A computer can also connect an optical drive to read and play CDs and DVDs, a network card and a router to the Internet and devices like printers and scanners. The motherboard, CPU, RAM, hard disk, graphics card and power supply, however, are the main components of a computer system.
