    Study Notes

    Digital Literacy Fundamentals

    • Digital literacy transcends computer use; it's about active engagement with the computerized world.

    Computer Evolution

    • The microchip (1947) miniaturized and sped up computers.
    • Smartphones now have more processing power than the Apollo 11 mission's computer.
    • ARPANET (1960s) originated from military information sharing needs.
    • TCP/IP (early 1970s) protocols enabled computer communication.
    • Internet ownership transitioned to the public around 1990, leading to the World Wide Web's emergence.
    • Internet and World Wide Web differ despite common association.

    Key Computing Concepts

    • Artificial Intelligence (AI) focuses on pattern recognition and decision-making.
    • Virtual Reality (VR) enhances gaming experiences.
    • Quantum computing aims for beyond binary processing.
    • Automation through machines and robots expedites tasks.
    • Computers perform four basic operations: input, processing, storage, and output.
    • Computers and brains both use senses to process information.
    • Computers understand binary (0s and 1s).
    • A byte is eight bits.
    • Computer bus systems connect devices.
    • Hertz measures frequency per second.
    • Giga (G) represents billions; Kilo (K) represents thousands.

    Hardware and Maintenance

    • Safely handling internal components involves unplugging power.
    • Discharging static electricity involves touching metal.
    • Operating systems (OS) manage application environments.
    • Applications (programs) enable user tasks.
    • UI (User Interface) is software/device interaction.

    Operating Systems and Software

    • Modern OSes provide graphical user interfaces.
    • OSes manage RAM for applications.
    • UEFI replaces BIOS, enabling user-friendly startup changes.
    • POST (Power-On Self-Test) checks hardware during startup.

    Software and Applications

    • Desktops are optimal for resource-intensive tasks (processing power, graphics).
    • Wearable tech (smartwatches) support calls and health monitoring.
    • Spreadsheet software organizes and calculates data.
    • Word processing mimics pen-and-paper document creation.
    • Software problems manifest as frequent restarts.

    Troubleshooting and Maintenance

    • Update software and restart for bug fixes.
    • Uninstall/reinstall problematic software.
    • Virus/malware scans enhance data security.
