A computer is a machine that can be programmed to perform arithmetic or logical operations automatically.
Modern computers can perform sets of operations known as program. These programs enable computers to perform a wide range of tasks.
A computer system is a “complete” computer that includes the hardware, operating system(software) and peripheral equipment.
Computer Hardware -these are the physical parts of a computer such as case, central processing unit(CPU),monitor, mouse, keyboard, speakers and motherboard.
Operating System (OS) -is the system software that manages computer hardware and provides services for computer programs.
These are the hardware components that are easily attached and removed into a computer and are controlled by the computer system,but they are not the main or core components of the computer.
Input Device – send data or instructions to computer, such as a mouse, keyboard, webcam, scanner and microphone.
Input/Output Device – performs both input and output functions, such as disk drive, USB flash drive and memory card.
