    Study Notes

    Introduction to Technology

    • Technology is revolutionizing the way people think, interact, and consume products.

    What is a Computer?

    • A computer is a programmable, multi-purpose machine that processes data into usable information.

    • The word "computer" comes from "compute," meaning to calculate.

    History Timeline

    • Abacus: First mechanical device for calculations, performing arithmetic.

    • Pascaline (1642): The first mechanical calculator, invented by French mathematician Blaise Pascal.

    • Analytical Engine (1833): Designed by British mathematician Charles Babbage, "Father of Computing.

    • Tabulating Machine (Herman Hollerith): Capable of reading, processing, and outputting data.

    The Evolution of Computers

    First Generation (1941-1956)

    • Used vacuum tubes and magnetic drums.
    • Examples: ENIAC and UNIVAC.

    Second Generation (1956-1963)

    • Introduced transistors, replacing bulky vacuum tubes.

    Third Generation (1964-1971)

    • Utilized integrated circuits (ICs) for smaller and faster processing.
    • Examples: IBM 1130 and UNIVAC 1107.

    Fourth Generation (1971-present)

    • Characterized by the development of microprocessors and the rise of personal computers (PCs).
    • Development of mouse and joysticks.
    • Ability to network computers.

    Fifth Generation (1980s - Present)

    • Focus on artificial intelligence (AI), parallel processing, and user-friendly interfaces.
    • This generation is still evolving.
    • Characteristics:
    • Development of GUI (Graphical User Interface).
    • Increasing computing power and miniaturization.

    Operating Systems

    • Real-Time OS (RTOS): Performs specific tasks in precise time.
    • Multiuser Operating System (Network OS): Allows multiple users to access the computer simultaneously.

    Functions of the Operating System

    • Hardware Coordination: Manages communication between the OS and input/output devices.
    • Memory and Storage Management: Manages RAM and virtual memory.
    • Software Application Coordination: Provides blocks of code for specific procedures (APIs).

    Starting Your Computer - The Boot Process

    1. Activating BIOS: Basic Input/Output System manages communication between the OS and peripherals.
    2. Self Test: Ensures key devices are operational.
    3. Loading the OS: System files and kernel are loaded into RAM.
    4. Checking Configurations: The registry stores settings for the OS and applications.

    Windows Interface

    • Desktop: Primary working area.
    • Taskbar: Displays open and favorite applications.
    • Start Menu: Provides access to all installed applications.

    User Interfaces for Other OSs

    • macOS and Windows have similar interfaces.
    • Linux interfaces often resemble the Windows and macOS paradigm.

    Organizing Your Files

    • Directory: Hierarchical structure of computer content (drives, folders, files).
    • File: Collection of data or program instructions treated as a single unit.
    • Folder: Collection of files.

    Data Transmission

    • Data is transferred as electrical signals, converted to binary form for processing.

    Binary Number System

    • A base-2 system with values of 0 or 1.

    Bits and Bytes

    • Bit: Binary digit, a 0 or 1.
    • Byte: Group of 8 bits representing a character or value.

    Types of Switches in Computers

    • Transistors: Electrical switches made from semiconductor material.
    • Integrated Circuits (Chips): Tiny regions of semiconductor material with multiple transistors.

    Types of Computers

    • Portable:
      • Cellphones
      • Tablets
      • Laptops
    • Stationary:
      • Desktop computers

    Cellphones

    • Components: Processor, memory, input/output devices.
    • Require their own OS and applications.

    Features of Smartphones

    • Internet access
    • PIM (Personal Information Management) features
    • Voice recording
    • Music file management
    • GPS services
    • Image and video capture
    • Computing for programs (word processors).

    Tablets

    • Similar to smartphones in features and OSs (iOS, Android, Windows).
    • Touchscreen interfaces and longer battery life.

    Laptops

    • Portable computers with a keyboard, monitor, and other devices in one case.
      • Considerations: Power, screen size, battery life, weight, and device count.

    Variations of Laptops

    • 2-in-1 PCs: Convert between laptop and tablet modes.
