    Study Notes

    Software and Software Engineering

    • Software is a set of instructions that tell a computer what to do. It's essential for operating a computer.
    • Without software, a computer is useless.
    • Two main types of software: systems software and application software.
    • System software manages the computer's hardware resources and allows application software to run. Examples: operating systems, compilers, assemblers.
    • Application software performs specific tasks for users. Examples: word processors, spreadsheets, database management systems, presentation software.
      • Word processors allow easy document editing and formatting.
      • Spreadsheets use tables for calculations.
      • Database management systems organize and manipulate data.
      • Presentation software creates slides and presentations.
    • Software design involves algorithms, data structures, and file structures.
    • Algorithms are step-by-step procedures for solving problems. They can be numerical or non-numerical (ex. sorting, searching).
    • Data structures are ways to organize and store data (ex. arrays, linked lists, trees, graphs).
    • File structures are how files are organized on a computer (ex. hierarchical, network).
    • Software engineering is a systematic and disciplined approach to software development for large projects, focusing on quality, cost efficiency, and time management.
    • Key attributes of software engineering: efficiency, reliability, reusability, maintainability.
    • Software engineers perform tasks like requirement analysis, design, development, testing, debugging, code review, and maintenance.
    • Software is also validated to ensure it's correct and complete.
    • Different software development life cycle (SDLC) models offer different approaches such as waterfall, incremental, V-model, spiral, and prototyping.
    • Waterfall is sequential with a rigid structure (no feedback or changes).
    • Incremental builds the software in small, iterative steps.
    • V-Model focuses on verification and validation throughout the development, while linking the testing phases to the design phases.
    • Spiral Model approaches by cycles of planning, risk assessment, engineering, and evaluation, focusing on risk mitigation.
    • Prototyping allows for gathering user feedback early, reducing risk.
    • Pseudocode is a high-level description of an algorithm, using structured English.
    • Pseudocode is more readable and language-independent as compared to actual programming code. It's useful for outlining and communicating logic before writing specific code.
