    Study Notes

    Computer Program

    • A computer program consists of a sequential set of instructions, or codes, written in a computer language to perform specific tasks.
    • Common types of software include system software, web browsers, utility software, multimedia software, and spreadsheet software.
    • Instructions must generally be executed sequentially unless specified otherwise for different execution flow.

    Computer Language

    • Refers to the grammatical rules that instruct a computer to execute tasks, also known as programming languages.

    Programming

    • Defined as the art and science of instructing computers using programming languages.
    • Involves writing codes for various applications such as websites, data analysis, and process automation.
    • Proficiency in programming leads to numerous career opportunities in fields like software development, web development, data science, and AI.
    • Enhances critical thinking, logical reasoning, and problem-solving abilities.

    Evolution and History of Programming

    • Initially based on writing machine code with binary instructions communicating directly with hardware.
    • High-level languages emerged to simplify coding with human-readable syntax.
    • A variety of programming languages and tools now exist to cater to different paradigms and domains.

    Programming Paradigms

    • Paradigms are approaches to organizing and structuring code, providing frameworks for problem-solving and software design.
    • Procedural Programming focuses on code organized into procedures or functions (e.g., BASIC, C, Java).
    • Object-oriented Programming (OOP) encapsulates data and behavior into objects, promoting modularity (e.g., Python, C#).
    • Functional Programming treats computation as mathematical function evaluation, focusing on consistency and avoiding side effects.

    Programming Languages

    • Languages divided into low-level and high-level:
      • Low-level languages provide intricate control over hardware (e.g., Assembly, Machine Language).
      • High-level languages are more user-friendly and abstract away hardware details (e.g., Python, C++, Java).
    • Language choice influenced by project requirements, performance specifications, community support, and available libraries/frameworks.

    Other Programming Terminologies

    • Syntax: Set of rules for valid statement formation in a programming language.
    • Command: Unique instructions for specific tasks (e.g., "print" command).
    • Integrated Development Environment (IDE): Software application for code formatting, syntax checking, and running/testing code.
    • Library: Pre-built collection of resources (objects/functions) for use in programming.
    • Interpreter: Executes high-level language instructions directly, without machine code conversion.
    • Assembler: Converts low-level assembly code into relocatable machine language.
    • Compiler: Translates high-level languages into machine-readable code.

    Algorithm

    • A precise set of steps generating a solution for a defined problem, expressed in natural language.
    • Example algorithm for the volume of a rectangle involves getting length, width, height, and displaying the calculated volume.

    Problem-Solving Process in Programming

    • Problem Analysis: Evaluate and outline problem requirements.
    • Algorithm Design: Create an algorithm for the solution.
    • Coding: Implement the algorithm in a programming language.
    • Execution: Verify the algorithm's correctness.

    Representing Algorithms

    • Pseudocode: Simplified description of an algorithm, easily understood by those with basic programming knowledge.
    • Flowchart: Diagrammatic representation of algorithm steps using symbols to depict the flow of logic.
      • Program Flowcharts: Visual representation of logical steps in a programming task.
      • System Flowcharts: Show system component interactions and data flow, illustrating how decisions affect processes.

    Flowchart Symbols

    • Standard symbols used in flowcharts for different operations include input/output, processing, predefined processing, comments, decision points, and connectors.

    Rules for Creating Program Flowcharts

    • A set of guidelines for constructing effective flowcharts for understanding programming tasks and processes.
