Objectives By the end of this lesson, you should know What computer hardware is List some examples of computer hardware
RECAP In our previous lessons, we learnt that the components of a computer system can be grouped into four: Hardware, Software, Liveware/user and procedures. In today's lesson we shall look at computer hardware.
DEFINITION A computer hardware refers to the physical or the tangible components of a computer that can be touched and felt. All peripheral devices are hardware components.
Without hardware, there would be no way of running the essential software that makes computers so useful. Although a computer can function only when both hardware and software are working together, the speed of a system will largely rely on the hardware used.
