Cable Types and Connectors

System Case

• Types: All-in-One vs. Tower
  • All-in-One:
    • Everything within the screen (like a laptop).
    • Space-efficient but expensive and hard to upgrade.
  • Tower:
    • Separate components, larger size.
    • Cheaper and easier to upgrade.
• Front Panel Ports and Features:
  • USB ports, audio/mic jacks, power button, optical drive.

Side and Rear Panel

• Side Panel: Provides access to internal components like the motherboard, RAM, graphics card, hard drives, power supply.
• Rear Panel: Contains ports of the motherboard, graphics ports, power supply unit (PSU), etc.

Types of USB Connectors

• USB 2.0: Type A, Type B, Type B Mini, Type B Micro.
• USB 3.0: New versions of Type A, Type B, Type B Micro with additional pins and wires.
• Compatibility: USB 2.0 can work in USB 3.0 ports but not vice versa.

Other Cables

• HDMI (High Definition Multimedia Interface): Commonly used for video and audio.
• DisplayPort: Developed by PC industry; similar to HDMI but royalty-free.
• Thunderbolt: Can be used for display or as a general peripheral interface; supports daisy chaining.
• Lightning (Apple): Used in iPhone and iPad; requires adapter for connectivity.

SATA and Legacy Cables

• SATA (Serial Advanced Technology Attachment): Used for hard drives and optical drives.
  • Types: Data Connector, Power Connector.
• Molex Connectors: Older power connectors, still used for case fans.
• Legacy Cables: IDE (Integrated Drive Electronics) also known as PATA cables.

Installing and Configuring Motherboards

Electrical Safety and ESD

• Unplug Devices: Always unplug before working on them.
• Electrostatic Discharge (ESD): Human body can damage electronics with static electricity.
• Anti-Static Tools: Anti-static wrist strap, anti-static mats, anti-static tools.
• Practical Tip: Touch the inside frame of the computer case to discharge static electricity.

Motherboard Connector Types

• CPU Socket: For the central processing unit.
• Memory Slots: For RAM; different colors indicate different channels.
• Disk Drive Connectors: SATA ports for data and power.
• Adapter Card Slots: PCIe for graphics cards and other expansion cards.
• I/O Ports: Input and output ports for peripherals.
• Coin Cell Battery (CMOS Battery): Keeps track of time and system settings; usually lasts 5-10 years.

Performance-Based Questions (PBQ)

• Practical exam questions about motherboard components.

Legacy Cable Types

IDE Cables

• Used for older hard drives and optical drives.
• Connected to the motherboard and devices via wide cables.

Serial Cables

• DB9 connector, RS-232 standard.
• Used for old modems, keyboards, and mice; occasionally used in server management.

SCSI (Small Computer System Interface) Cables

• Rarely used, found in older systems with bespoke applications.

Adapter Cables

• Passive Cables: Different connectors on each end.
• Active Cables: Translates signaling between different interface types.
• Examples: HDMI to VGA, USB hubs, USB to Lightning, etc.
