The system unit, also known as the tower or chassis, is the main part of a computer that houses the central processing unit (CPU), memory, and other internal components. It is the “brain” of the computer and is responsible for executing instructions and processing data.
Peripheral devices, on the other hand, are external devices that are connected to the computer to expand its functionality. Examples of peripheral devices include keyboard, mouse, monitor, printer, scanner, and external hard drive. They provide additional input and output options for the computer and allow the user to interact with the computer in different ways, such as typing, pointing, and displaying information.
