In the realm of computer science, a system input/output (Systems I/O) is an essential component that enables communication between a computer system and its external environment. It serves as a bridge to exchange data and control signals between the internal processing units and various input and output devices, ranging from keyboards and mice to printers and storage devices.
A fundamental aspect of Systems I/O is the concept of input/output devices. Input devices allow users to interact with the computer system by providing it with data, instructions, or commands. Keyboards, mice, touchscreens, scanners, and microphones are common examples of input devices. Output devices, on the other hand, present the results of the computations or operations performed by the computer to the user. Printers, monitors, speakers, and plotters are prominent examples of output devices.
