    Study Notes

    Computer Organization

    • A computer performs five major operations: input data, store data, process data, output results, and control operations.
    • The functional units include Input Unit, Control Unit (CU), Memory Unit, Arithmetic Logic Unit (ALU), and Output Unit.
    • The Control Unit supervises input, output, processing, and storage, ensuring operations are performed in a structured sequence.

    Memory Unit and ALU

    • Memory Unit stores data and instructions required for processing.
    • The Arithmetic Logic Unit (ALU) carries out basic operations: addition, subtraction, multiplication, division, logical operations, and comparisons.
    • The combination of ALU and CU is referred to as the Central Processing Unit (CPU), considered the "brain" of the computer.

    Peripheral Devices

    • Peripheral devices are external components connected to a computer.
    • They are categorized as Input Devices, Output Devices, and Other Peripherals.

    Input Devices

    • Accept data and instructions from users.
    • Common input devices include:
      • Keyboard: Standard device for text input, typically a QWERTY layout with around 104 keys.
      • Mouse: A common pointing device for user navigation.
      • Touch Screen: Allows direct interaction with display.
      • Microphone: Captures voice input, available as desktop or handheld types.
      • Track Ball: A stationary pointing device that requires less space, operates by rotating a ball.

    Output Devices

    • Return processed information to users.
    • Common output devices include:
      • Monitor: Displays visual output; two main types are CRT (Cathode Ray Tube) and LCD (Liquid Crystal Display).
      • Printers: Produce physical copies of digital documents.
      • Plotters: Used for printing vector graphics.
      • Speakers: Output sound.

    System Software

    • Set of programs executed upon booting, activating different computer units.
    • Operating System (OS) manages hardware and software resources and provides an interface for user interaction.
    • Popular operating systems include UNIX, Windows, and Linux.
    • Utility programs enhance the OS by providing additional functionality like file compression, antivirus protection, etc.

    Programming Languages

    • High-level languages are user-friendly, while assembly language is machine-dependent.
    • Examples of programming languages include:
      • BASIC: Beginner-friendly and was widely used in early microcomputers.
      • COBOL: Standard language for commercial applications.
      • FORTRAN: Used in scientific and mathematical applications.
      • C: Structured programming language for various applications.
      • C++: Object-oriented language, widely used in general programming.

    Compiler and Assembler

    • Compiler: Converts high-level language programs (source program) into machine language (object program).
    • Assembler: Translates assembly language programs into machine language.
    • Both tools are essential for the execution of programs on computers, ensuring human-readable code is transformed into machine-readable code.
