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

3 Types of Ports Serial port – Transfers data one bit at a time – Speed: very slow … – Legacy (ex mouse)

4 Types of Ports Parallel – Transfers eight bits of data simultaneously (transmits “in parallel”) – Speed: 500 K bps – (faster that serial – Legacy (ex printer)

5 Types of Ports 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

6 Types of Ports Ethernet – Connects computers to networks, modems – (newer speed:10,000 M bps ) – Often listed on computer spec sheet as: 10/100/1000 M bps Fast Ethernet LAN Ethernet Port Ethernet jack (RJ-45 connector)

7 Types of Ports 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 /S-video– 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) S= Super ; DVI= Digital video interface HDMI VGA S-video DVI DVI VGA
