List at least six hardware components found in a typical computer.
Computers contain different hardware components, such as CPU, internal memory, hard disk drive, optical disk drive, motherboard, video card and sound card.
Explain the relationship between hardware and software in a computer system.
Software is necessary for computer hardware to function. There are different types of software - application software and system software.
