© 2008 Prentice-Hall, Inc. 1 Ports for peripheral devices (speeds in bits per second) –Serial 115K bps, –Parallel 500K bps –USB 480M bps (2.0) –USB 4800M bps (3.0) –Ethernet 100/1000/10000M bps –Tele. modem 56K bps –FireWire (or 1394) 400M bps, 800M bps, and 3.2G bps (= 3200M bps) –Audio ports –VGA, DVI (monitor) –HDMI (TV) –Thunderbolt 10 G bps

2 Expansion cards slotted into motherboard Notice in the picture the 2 expansion cards have ports on them

Legacy ports Serial port Legacy means old in computer speak Parallel: 3

4 USB Universal serial bus (USB) – Speeds: USB 2.0: 480 M bps USB 3.0: 4800 M bps (= 4.8 G bps) Competitive speeds to Firewire port USB Port USB Connector

5 Ethernet – Connects computers to networks, modems – latest speed: 10,000 M bps – Often listed on computer spec sheet as: 10/100/1000/10000 M bps Ethernet Port Ethernet jack (RJ-45 connector)

6 FireWire FireWire (or 1394) – Max speeds: 400 M bps 800 M bps 3.2G bps (in develop.) – Digital cameras, etc – Comes in several different configs. Know the 5-sided hexagon one! FireWire Port FireWire Connector

Ports for multimedia and monitor VGA – to connect CRT and older LCD monitors DVI – to newer LCD monitors, TVs (DVI is video only, not audio) HDMI – newest way to connect to TV, home theatre equipmt (Hi Def Multimedia Interface, audio and video) DVI= Digital video interface HDMI VGA DVI DVI VGA

Thunderbolt port Latest and greatest port 10 G bps Uses fiber optics Apple first to incorporate this port on its products

9 Types of Wireless Ports Bluetooth Radio waves IrDA – Uses infrared light – Direct line of sight
