A location used for transferring data in or out of a computer.

See media access port.

1. A hardware location used for passing data into and out of a computing device. Personal computers have various types of ports, including internal ports for connecting disk drives, monitors, and keyboards, and external ports, for connecting modems, printers, mouse devices, and other peripheral devices. 2. In TCP/IP and UDP networks, the name given to an endpoint of a logical connection. Port numbers identify types of ports. For example, both TCP and UDP use port 80 for transporting HTTP data.

A connection on a computer where devices that pass data to and from the computer are physically connected. Ports are numbered from 0 to 65535. Ports 0 to 1024 are reserved for use by certain privileged services. See also Authentication port, local port, remote port, source port.

A connection through which a device is attached to an I/O bus or to the storage network, or the representation of this physical connection to the link hardware.

A port is an interface between a computer and other computers or devices. A port can be used to transfer data from one computer to another by a cable that links connecting ports.

A virtual data connection in software, which programs use to exchange data directly. The data transfer ideally happens between two or more remote computers. The protocols that are used to transfer the data between ports is TCP and UDP.

A port is an interface between the computer and other computers or the devices that are used to transfer data between computers.
