(CPU) of a computer system. A central processing unit (CPU)‚ also referred to as a central processor unit‚ is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical‚ logical‚ and input/output operations of the system. In the computer industry‚ the terms computer and CPU are often used interchangeably. Computing power starts with the most limited microcomputers which are laptop computers‚ netbook computers‚ PDAs and cell phones

Input devices Input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. Input device is any machine that feeds data into a computer. For example‚ a keyboard is an input device‚ whereas a display monitor is an output device. Input devices other than the keyboard are sometimes called alternate input devices. Mice‚ trackballs‚ and light pens are all alternate
