Computer Hardware

Generally speaking computers are machines that solve tasks and calculations as a result of commands or applications. They work due to the interaction of hardware and software.

Hardwares are the physical parts of the computer that you can see and touch. The most important component of the hardware is the micro processor. It is the central control unit of the computer, where commands are translated and calculations are done.
