The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices.
Input/output completion port (IOCP) is an API for performing multiple simultaneous asynchronous input/output operations in Windows NT versions 3.5 and later, [1] AIX [2] and on Solaris 10 and later. [3] An input/output completion port object is created and associated with a number of sockets or file handles.
The user's response determines the purpose of the port, which is physically a 1/8" tip-ring-sleeve mini jack. Some auto-detect ports can even switch between input and output based on context. As of 2006, manufacturers have nearly standardized colors associated with ports on personal computers, although there are no guarantees.

From the computer user's perspective, the USB interface improves ease of use in several ways: The USB interface is self-configuring, eliminating the need for the user to adjust the device's settings for speed or data format, or configure interrupts, input/output addresses, or direct memory access channels.

A GPIO port is a group of GPIO pins (often 8 pins, but it may be less) arranged in a group and controlled as a group. GPIO abilities may include: [2] GPIO pins can be configured to be input or output; GPIO pins can be enabled/disabled; Input values are readable (usually high or low) Output values are writable/readable
A peripheral can be categorized based on the direction in which information flows relative to the computer: The computer receives data from an input device; examples: mouse, keyboard, scanner, game controller, microphone and webcam; The computer sends data to an output device; examples: monitor, printer, headphones, and speakers
