Summary of Study Notes

• Information about the active explorer lesson one

  • A famous archaeologist and explorer, Faried Hibbert, works for National Geographic.
  • He studies past civilizations through excavation, observation, and documenting artifacts and locations.
  • He conducts training courses worldwide for students and colleagues.
  • He uses various digital tools in his work.
  • Word processing to write reports.
  • Excel for creating charts.
  • PowerPoint presentations to show project results, emphasizing clear and easy-to-read slides.
  • Email for formal communication (as well as written mail, or in-person delivery of documents.).
  • Zoom and WhatsApp for virtual meetings (necessary due to time zone differences).

• Digital tools for collaboration

• Meetings and discussions often involve documentation of comments and observations in Word documents, sent as emails or files, ensuring comprehensive and shared updates.

• Virtual meetings and video conferences are efficient learning tools allowing for audio communication and sharing of information via presentation screens.

• Educational Institutions use online platforms such as YouTube or specialist channels to offer learning materials for students.

• Digital tools and devices

  • Flash memory is used for data transfer and storage.
  • HDMI is a high-definition multimedia interface cable used to transmit sound and video from devices.
  • External hard drives are used for faster storage and backup.
  • Routers connect computers to the internet via Wi-Fi or Ethernet cables.
  • Ethernet cables are wired for computer-to-router connections.
  • Ethernet ports are the connection point for Ethernet cables; they are more stable and faster than wireless connections and used when speed and stability are a priority.
  • The binary system used in computers (0 or 1), where each character is 8 bits, and a byte equals one character.
  • Units of measurement: kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB).

• Computer Networks

  • LAN (Local Area Network) connects computers and other devices (e.g., printers) within a limited area, such as a home or building.
  • Internet (Global Network): connects computers worldwide enabling communication between people across the globe.
  • Gateway (e.g., router): is required to connect to the Internet through an Internet Service Provider (ISP).
  • WWW (World Wide Web): part of the Internet with interconnected web pages and hyperlink browsing.
  • Intranet: a private network for specific user groups within an organization (e.g., a school or business).
  • Closed network: a network limited to a specific group or institution (e.g., a school computer lab, where all devices are on the network).
  • The emergence of internet connections using telephone lines (dial-up), high-speed connections (DSL), Wireless technologies (Wi-Fi), and hotspots improved the ease and speed of Internet connectivity.
  • Open networks such as the Internet are accessible to everyone.

• Digital Communication Tools

  • Internet of Things (IoT): connects home appliances to the internet for remote control (e.g., smart refrigerators, washing machines).
  • Bluetooth: Wireless technology connecting mobile devices over short distances (e.g., headphones, keyboards).

• Digital Commerce and Safety

  • E-commerce: online buying and selling.
  • Digital privacy: following security measures when providing personal information on the internet.
  • Taking precautions when shopping online by asking a parent or guardian if necessary .
  • Websites: internet-based platforms with unique names.

• Troubleshooting Computer Issues

  • Identifying the problem: pinpoint whether it is hardware or software-related, and document the specific functionality problem.
  • Brainstorming possible solutions: explore different options, making a list of possible causes for the problem.
  • Testing solutions: apply possible solutions and test how they work. Note the exact steps taken.
  • Documenting the outcome and learnings from the troubleshooting process: assess if the solution worked, or if there was a learning moment from testing the solution.
  • Seeking assistance: if troubleshooting fails, consult a teacher or family members to resolve the problem.
  • Problems like slow computer performance (closing unnecessary software, updating software, or removing unwanted apps) and slow internet speed (checking network connections, using a different network connection—wired instead of Wi-Fi—updating the network software) can be solved with these methods.

• Digital File Management

  • File: data unit (e.g., video, text, audio, image).
  • Folder: collection of files, can contain subfolders.
  • Organizing files: naming and positioning files within relevant folders.
  • Structure: creating new folders.
  • Using a system to create an overall organizational structure.
  • Using digital tools and devices (e.g., scanner or camera, flash memory) to store and share information.

• Digital Information Strategies

  • Research steps: developing a research topic, breaking it into smaller subtopics, identifying keywords, gathering information, and organizing findings for a presentation.
  • Information Sources: Multiple reliable sources for information gathering.
  • Critical Evaluation of Sources: Assessing information quality and credibility, using reliable sources for strong, thorough research and verifying information from multiple sources for complete, accurate research

• Information Sharing

  • Internet: global network for information sharing.
  • Intranet: secured network limited to a specific group (e.g., school).
  • Microsoft Excel: used for data organization and calculations (e.g., sorting data alphabetically, creating formulas for calculations).

• Digital Security

  • Protecting personal information (PII): details like name, address, date of birth, passwords.
  • Phishing: fraudulent emails or messages designed to steal personal information.
  • Smishing: phishing attacks through text messages.
  • Protecting Yourself from Phishing Sites: Verifying website legitimacy before entering personal information.
  • Multi-factor authentication: security method to confirm a user's identity using multiple factors (e.g., passwords, codes sent to a phone).

• Digital Content Protection

  • Copyright laws protect various digital content (e.g., images, music, videos).
  • Plagiarism: avoiding copyright infringement.
  • Attribution: accurately citing the source of information.
  • Respecting copyright for all materials (i.e. pictures, music, films).

• Digital Sources -Reliable sources of information: using well-established and trusted sources are good for verifying information
