EXTERNAL CONNECTIVITY
EXTERNAL CONNECTIVITY A port is a connector on the motherboard or on a separate adapter that allows a device to connect to the computer. Male ports have metal pins that protrude from the connector. A male port requires a cable with a female connector. Female ports have holes in the connector into which the male cable pins are inserted.
VIDEO PORTS
A video port is used to connect a monitor. Today, there are two types normally seen and they both have three rows. The older one is a three-row, 15-pin female D-shell. The 15-pin female connector is used to attach VGA monitors. Even though it can have different types of monitors attached, it is normally referred to as a VGA port. The newer port is called a DVI port (Digital Visual Interface) and it has three rows of square holes. This is the newer video port and is used to connect flat panel digital monitors. Flat panel monitors can also use the older VGA port. Some video adapters also allow you to connect a video device (such as a television) that has an S-Video port.
