An input device is a hardware or peripheral device used to send data to a computer. An input device allows users to communicate and feed instructions and data to computers for processing, display, storage and/or transmission.
Examples of input devices include keyboards whicha allow users to input data and pointing devices and game controllers such as mouse and joysticks.
Input also may come from other computers via input/output (I/O) devices like network adapters and Bluetooth ports.
An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form.
Examples of output devices include:
CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place.
The computer memory is a temporary storage area. It holds the data and instructions that the Central Processing Unit (CPU) needs. Before a program can be run, the program is loaded from some storage medium into the memory. This allows the CPU direct access to the program.
An input device is the medium through which data and instruction are entered into the computer. They are:
The devices which are used to produce or display result of processed data is known as output devices. Their types are.
i. Soft copy output device - monitor.
ii. Hard copy output device - printer.
CPU is an electric brain to computer which process and controls all the activity of computer system. The section of CPU are:
The computer memory is a temporary storage area. It holds the data and instructions that the Central Processing Unit (CPU) needs.
