    Study Notes

    Common Computer Ports and Cables

    • Ports are physical docks for connecting peripheral devices to computers.
    • Peripheral devices include keyboards, mice, printers, projectors, flash drives, speakers, and microphones.

    Types of Ports and Cables

    • Computer Power Cords: Supply power from AC wall sockets; laptops need specific adaptors for wattage.
    • Universal Serial Bus (USB) Ports: Rectangular ports used for most peripherals; available in three types: Type A, Type B, and Type-C.
      • USB Type A: Standard connector; includes USB 2.0 (black) and USB 3.0 (blue) with data transfer speed differences.
      • USB Type B: Primarily connects computers to printers.
      • USB Type-C: Uses Thunderbolt technology for faster data transfer; identified by lightning bolt symbol.

    Safely Disconnecting USB Devices

    • Two methods exist:
      • Use Show/hide icon on the taskbar or right-click in Explorer folder and select Eject for safe removal.

    Video Ports and Cables

    • Major video ports include VGA, DVI, HDMI, and DisplayPort.
      • VGA Ports: 15-pin connectors found on older devices; must be inserted directionally to avoid damage.
      • DVI Ports: Provides high-speed digital connection between computer and monitor, insertion requires correct orientation.
      • HDMI Ports: Standard on most new devices; available in standard, mini, and micro sizes.
      • DisplayPort: Offers superior picture quality and higher resolution than HDMI.

    Emerging Technology

    • USB 4.0 Technology: Expected to provide 10,000 Mbps transfer speeds, significantly faster than USB 3.0.

    Audio Ports and Cables

    • Audio ports connect speakers, microphones, and headphones, typically using 3.5 mm jacks.
      • Port Colors:
        • Pink: Microphone
        • Green: Speakers/Headphones
        • Blue: In-line port for playback and recording.
      • Additional colors (grey, black, orange) may indicate surround sound capabilities.
