A common computer input device, a keyboard. A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance.
This technology approach needs special hardware support to be useful and was first the domain of mainframes and other large computers. Nowadays, most personal computers are equipped for this task, but for long-term operation or critical systems, specialized server hardware may be needed.
An output device is any piece of computer hardware that converts information or data into a human-perceptible form or, historically, into a physical machine-readable form for use with other non-computerized equipment. It can be text, graphics, tactile, audio, or video.
A hardware can be controlled from a software with the help of a middle device called hardware controller, this hardware controller can be used to perform various automated task from hardware, generally hardware controller consist of GPIO(general purpose input and output) pins, these pin's behaviour controlled by the piece of code.
