    Study Notes

    Computer Hardware vs. Peripherals

    • Computer hardware encompasses all physical components of a computer, including the system unit and internal parts.
    • Peripherals are external devices connected to a host computer, expanding its capabilities but not part of its core architecture.
    • Common peripherals connect via ports to enhance the functionality of the system.

    Input Devices

    • Input devices allow the entry of data or instructions into a computer.
    • Examples include the keyboard, mouse, microphone, scanner, digital camera, and PC video camera.

    Mouse

    • A pointing device used to manipulate on-screen objects, typically featuring two buttons and a scroll wheel.
    • Key operations:
      • Clicking: Pressing a button once.
      • Double-clicking: Pressing a button twice rapidly to open files or applications.
      • Dragging: Holding a button and moving the mouse to select items.
    • Safety tips for mouse use:
      • Keep the mouse at elbow level and don’t grip it tightly.
      • Move it by pivoting the arm and take breaks every 15 to 20 minutes.

    Other Pointing Devices

    • Trackball: Stationary device with a ball on top for precise control, suitable for gaming and design.
    • Touchpad: Sensitive to pressure and motion, allowing pointer movement via finger slides.
    • Joystick: Controls actions in simulated environments through directional movement.
    • Light Pen: A handheld device that detects light for graphic design tasks.
    • Touch Screen: A display that allows user interaction through touch.

    Keyboard

    • An essential input device featuring multiple sections for entering data.
    • Comprises typing keys, numeric keypad, functional keys (F1, F2, etc.), and special keys like Enter, Backspace, and Space bar.

    Output Devices

    • Output devices convert digital data into a physical format or visual display.

    Monitor

    • The primary output device, forming images from pixels, with clarity based on pixel count.
    • Types:
      • CRT (Cathode-Ray Tube): Bulky, using electron beams.
      • Flat-Panel Display: Lightweight, categorized into:
        • Emissive Displays: Convert electricity to light (e.g., LEDs).
        • Non-Emissive Displays: Use optical effects (e.g., LCDs).

    Printers

    • Convert digital documents into physical copies, with two main types:
      • Impact Printers: Use physical striking to print (e.g., dot matrix).
      • Non-Impact Printers: Use inkjet or laser technology without striking.

    Comparison of Hard Copy and Soft Copy

    • Hard copy is more accessible and less prone to changes compared to soft copy, which requires a computer to read and is more transient.

    Storage Devices

    • Essential for holding data, instructions, and information for future use, including floppy disks, USB drives, and hard disks.
    • Primary Memory: Temporary storage directly accessed by the CPU, categorized into RAM (volatile) and ROM (non-volatile).
    • Secondary Memory: Non-volatile storage like hard disks, slower than primary but offers higher capacity and permanent data storage.

    Processing System Unit

    • Contains electronic components necessary for processing data.
    • The form factor defines the size and layout of the system unit.

    Devices with Dual Functions

    • Devices serving both input and output roles include:
      • Touch Screen
      • Hard Disk Drive
      • USB Flash Drive
      • Modem
