Study Notes

Introduction to Programming

  • A computer is a machine that performs tasks according to specific instructions.
  • Input devices provide data to the computer.
  • The processor manipulates the data at high speed.
  • A program guides the processor.
  • Computers have hardware (physical parts) and software (programs).

Basic Components of a Computer

  • Hardware:

    • Central Processing Unit (CPU): The "brain" of the computer, containing tiny electrical components performing the fundamental computations. Examples include Pentium, Athlon and SPARC processors.
    • Memory: Stores data and instructions needed by the CPU.
      • Main Memory (RAM): Used for actively used programs and data. Volatile, meaning data is lost when the computer is turned off.
      • Secondary Memory: Stores programs and data for long-term use. Examples include hard drives, CDs, DVDs, and flash drives. Non-volatile, meaning data persists when the computer is off.

  • Software: The intangible part of a computer, consisting of the data and programs for a computer.

Input and Output Devices

  • Input devices allow data to enter a computer system, including keyboards, mouses, and microphones.
  • Output devices display data from the computer system, examples are monitors, printers, and speakers.

Programming Languages

  • Programming languages are a standardized way to communicate instructions with a computer; examples are Machine Language, Assembly Language and High-Level Languages.
  • Machine Language (machine code) is the lowest-level language interpreted directly by the computer.
  • Assembly Language is a low-level language converted to machine code using an assembler.
  • High-Level Languages are human-readable languages translated into machine code by compilers/interpreters. These languages can have multiple paradigms (styles of programming) like functional, imperative, object-oriented, event-driven, and logic.

Program Development Cycle

  • Problem Definition: Clearly define the problem and input/output requirements.
  • Problem Analysis: Decompose the problem into smaller, solvable sub-problems.
  • Algorithm Design: Describe the steps to solve the problem in clear, unambiguous terms, using either human language, pseudocode or flowchart.
  • Coding and Debugging: Write the program in a chosen language, find and fix errors.

Number Systems

  • Decimal: Base-10 number system (0-9).
  • Binary: Base-2 number system (0 and 1).
  • Octal: Base-8 number system (0-7).
  • Hexadecimal: Base-16 number system (0-9, A-F).
  • Conversion processes exist to convert from one number system to another.

Data Types

  • Data type classifies the type of value a variable holds.
  • Examples of basic data types include int, float, double, char, signed, and unsigned.
