Computer Science Course GCE A Level Cameroon. Computer Input/Ouput Devices – GCE A level Cameroon Lesson. The computer system essentially consists of three components: input devices, central processing unit and output devices. In the computer terminology, a device can be referred as a unit of hardware, which is capable of providing input to the computer or receiving output or both. kamerpower.com

The input devices are used to provide data to the central processing unit (CPU) for processing. After processing, the input data are converted into meaningful information and this output is presented to the user with the help of output devices. When the term ‘device’ is used, it includes keyboard, mouse, display monitors, printers and other hardware units.

The aim of this chapter is to familiarize you with various types of output and output devices along with their advantages, disadvantages and applications.
