    Computer Types

    • Mainframe: Capable of supporting hundreds to thousands of users simultaneously, very powerful
    • Supercomputer: Executes millions of instructions per second, incredibly fast
    • Laptop: Portable, AC or battery-powered personal computer, typically has similar functionality to desktops, some sacrifice functionality for portability
    • Netbook: Highly portable, cheaper than desktops or laptops, less processing power but suitable for internet use and email
    • Mobile Device: Handheld computers with varying levels of processing power, some can do tasks like desktops or laptops
    • Tablet Computer: Portable, touch-sensitive screen for interaction, optimized for media consumption and web browsing, use virtual keyboard
    • Smartphone: Powerful mobile phone with app capabilities, essentially small tablet computers

    Introduction to Computers

    • A machine that processes, calculates, and performs operations based on software or hardware instructions
    • Accepts data (input), processes it, and produces information (output)
    • Stores data for later retrieval
    • Used for various purposes: web browsing, document creation, video editing, game playing, etc.

    Basic Concepts of Computer

    • Electronic device for storing and processing data, providing fast and accurate results

    Data, Information, and Knowledge

    • Data: Unstructured facts and figures, lacking context or organization
    • Information: Data with relevance and purpose, contextualized, categorized, and calculated
    • Knowledge: Implies understanding and know-how, shaped by individual experience and used to evaluate new information

    Computer Classification

    • Personal Computer (PC): Small, single-user, based on a microprocessor
    • Workstation: Powerful, single-user computer, more powerful microprocessor and high-quality monitor than PC
    • Minicomputer: Multi-user, supports 10 to hundreds of users simultaneously

    Computer Components

    • Scanner:  Input device for scanning documents into soft copies
    • LCD (Liquid Crystal Display): Output device, used as a monitor
    • Motherboard: Combination of electronic circuits
    • Sound Card: Electronic circuits for sound output
    • Graphics Card: Electronic circuits for visual output to the monitor

    Computer Software

    • Software: Logical programs for handling and problem-solving
    • System Software: Manages the entire computer system
    • Application Software: Designed to solve a specific problem
    • Embedded Software: Integrated with hardware for specific tasks
    • Proprietary Software: Requires purchase for use, vendor-controlled
    • Open Source Software: Freely available, modifiable, and reusable under the same license
