  1. Ports for peripheral devices • Types of ports w/ speeds (= transfer rates): • Serial 115K bps, • Parallel 500K bps • USB 480M bps (2.0) • USB 4800M bps (3.0) • Ethernet 100M,1000M bps • Tele. modem 56K bps • FireWire (or 1394) • 400M bps, 800M bps, and • 3.2G bps (= 3200M bps) • Audio ports • VGA (monitor), DVI, s-video • HDMI

  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 jack (RJ-45 connector) Ethernet Port

  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

  8. 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

  9. Types of Wireless Ports on Test 2 • IrDA • Uses infrared light • Direct line of sight • Bluetooth • Radio waves
