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.
