Input/Output (I/O) is a computer system's information processing system that sends and receives data from a device, network, or hardware component. The I/O subsystem of a computer manages all the computer system's input and output operations. It also provides a way for the central system and the outside environment to communicate efficiently. The I/O control method controls how data is transferred between the computer and connected devices. Each I/O device connected to the computer is constantly checked for inputs.

Input/Output (I/O) is a computer system's information processing system that sends and receives data from a device, network, or hardware component. The I/O subsystem of a computer manages all the computer system's input and output operations. It also provides a way for the central system and the outside environment to communicate efficiently.
The I/O control method controls how data is transferred between the computer and connected devices. Each I/O device connected to the computer is constantly checked for inputs. When it receives an input signal from a device, it carries out that request until it no longer receives an input signal.
