    Study Notes

    Standard Keyboard Layout

    • Key groups include alphanumeric keys, numeric keypad, function keys, modifier keys, and cursor-movement keys.
    • Most standard keyboards feature around 100 keys and utilize the QWERTY layout.

    Input Devices

    • Common input devices include keyboard, mouse, microphone, touch screen, scanner, and webcam.
    • Manual input devices enable human interaction with computers; examples are joystick, remote control, graphics tablet, and light pen.

    Computer Hardware

    • Computer hardware consists of tangible physical components, including machinery, wires, transistors, and circuits.
    • Common hardware parts include monitor, modem, system unit, mouse, speaker, printer, and keyboard.

    Computer Software

    • Software refers to instructions and documentation that dictate computer operations.
    • Types of software include system software (operating systems) and application software (software for specific tasks).

    Computer Definition and Functionality

    • A computer processes input data according to rules, producing output and storing information for future use.
    • Core functionality: Data input → Processing → Information output.

    CPU Components

    • The Central Processing Unit (CPU) comprises three main elements:
      • ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations.
      • Control Unit (CU): Directs and coordinates the operation of computer components.
      • Registers: Temporarily stores data to be executed next.

    Solid-State Drive (SSD)

    • SSDs utilize flash-based memory, replacing mechanical hard disks for faster performance.
    • Benefits of SSDs include:
      • Enhanced speed: Lower read access times and quicker data throughputs.
      • Gaming: Improved performance for modern games requiring fast file loading.
      • Mobility: Reduced power consumption enhancing battery life and increased durability against data loss.

    Data Storage Evolution

    • Key advancements in data storage:
      • 1950s: Introduction of tape drives.
      • 1960s: Emergence of disk data storage and cassette tapes.
      • 1970s: Adoption of floppy disks (5.25" and 3.5").
      • 1980s: Development of hard disk drives (HDDs).
      • 1990s onward: Transition to CDs, DVDs, USB drives, and solid-state drives.

    Hard Disk Drive (HDD)

    • HDDs are traditional storage devices involving moving parts on magnetized surfaces.
    • They provide fast access to large data amounts but have higher latency and power requirements compared to SSDs.

    SSD versus HDD Comparison

    • Speed: SSD offers lower latency and faster read/write capabilities than HDD.
    • Power: SSDs consume less power, generating no heat or noise while HDDs generate heat and noise due to moving parts.
    • Weight: SSDs are lighter than HDDs due to the absence of mechanical components.

    Upgrading to SSD

    • Replacing an HDD with an SSD can significantly enhance an older computer's performance.
    • A one-terabyte SSD can be acquired for under JOD100, providing a cost-effective performance improvement.

    Central Processing Unit (CPU)

    • The CPU, known as the processor, orchestrates all computational functions and processes in the computer system.
