CEVAP:

A typical computer has the following hardware components: a CPU, memory, motherboard, storage device(s), and input/output devices. The core hardware components reside in a computer case, which acts as a protector as well as a house. The most commonly used computer case type is the tower (p:41, Figure 2.2). At the back of the computer case, there are some connectors for input/output devices such as keyword, mouse, monitor, joystick, printer, scanner, etc. These external peripheral devices are called either input devices or output devices depending on the direction of data flow between computer and the peripheral device.
