Input/Output port--Any socket in the back of the computer that you use to connect to another piece of hardware.
I/O stands for input/output. I/O is the communication between a computer and its user, its storage devices, other computers (via a network) or the outside world. The I/O port is the logical channel or channel endpoint in an I/O communication system.
A general term that represents connectors and terminals for inputting/outputting data from/to a computer. Input devices include a keyboard and mouse; output devices include a display. Floppy disk drives and hard disk drives are used both as input and output devices.
The way in which data is transferred between an input or output device and the microprocessor. It is used by the CPU (central processing unit) to send and receive data.
A bi-directional port that allows data to be transmitted back and forth between devices.
A channel through which data is transferred between an input or output device and the microprocessor. The port appears to the CPU as one or more memory addresses that it can use to send or receive data.
Short for Input/Output Port A connector on the computer where you plug in a cable from another device and through which information can flow between the two units.
A hex memory address used by a device or program to exchange data with the rest of the computer system.
Connection to a CPU that provides a data path between the CPU and external devices, such as a keyboard, display, or reader. It may provide input only, output only, or both input and output.
O (input/output), pronounced "eye-oh," describes any operation, program, or device that transfers data to or from a computer. Typical I/O devices are printers, hard disks, keyboards, and mouses. In fact, some devices are basically input-only devices (keyboards and mouses); others are primarily output-only devices (printers); and others provide both input and output of data (hard disks, diskettes, writable CD-ROMs).
