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.
