Such as printers, scanners and digital cameras. Memory sticks can also be plugged into a USB port allowing you to copy data to or from your hard disk. Network Port RJ-45 Plug  To plug a network cable into your computer which then lets you communicate with other computers connected to your local network or to other computers via the Internet. 12 PUA – Computer Center – UEC01  Monitor (VGA) Port  A Video Graphics Array (VGA) connector is a three-row 15-pin connector. The 15-pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, and high definition television sets. Monitor (HDMI) Port  High-Definition Multimedia Interface (HDMI) such as a display controller, a compatible computer monitor, video projector, digital television, or digital audio device. 13 PUA – Computer Center – UEC01  FireWire Port  FireWire is an interface from Apple Inc. that allows high data transfer between your computer and a compatible device such as a digital camera. Audio Port  Audio connectors is electrical connectors (or optical connectors) - plugs and sockets - for carrying audio signal. Back 14 PUA – Computer Center – UEC01  2.
