    Study Notes

    Internet for Grade 12 - Study Notes

    • Definition of the Internet: A global network of interconnected computer networks using standardized protocols (TCP/IP) for communication and data exchange.

    • Key Internet Protocols:

      • TCP/IP (Transmission Control Protocol/Internet Protocol): Fundamental protocols for internet communication, establishing connections, ensuring data integrity, and routing data packets.
      • HTTP (Hypertext Transfer Protocol): Transfers web pages and other hypermedia content.
      • HTTPS (Hypertext Transfer Protocol Secure): Secure version of HTTP, employing encryption for secure data transmission.
      • FTP (File Transfer Protocol): Used for transferring files between computers.
      • SMTP (Simple Mail Transfer Protocol): Used for sending and receiving email messages.

    • Internet Architecture:

      • Client-server model: Fundamental internet model, with clients requesting services from servers.
      • Network Access Points (NAPs): Critical connection points for internet service providers (ISPs) facilitating global communication.

    • Internet Addressing:

      • IP Addresses: Unique numerical addresses assigned to each internet-connected device for location and communication.
        • IPv4: Older version using four sets of numbers (e.g., 192.168.1.1).
        • IPv6: Newer version with a longer format addressing the limitations of IPv4 addresses (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
      • Domain Names: Human-readable names (e.g., google.com) that map to IP addresses, simplifying navigation. DNS (Domain Name System) translates domain names to IP addresses.

    • Internet Services:

      • Web browsing: Accessing and displaying web pages using web browsers (e.g., Chrome, Firefox).
      • Email: Sending and receiving electronic messages.
      • File sharing: Transferring files between computers using protocols like FTP.
      • Instant messaging: Real-time communication with other users.
      • Social networking: Connecting and interacting with other users.
      • Video conferencing: Real-time audio and video communication.
      • VoIP (Voice over Internet Protocol): Making phone calls over the internet.
      • Online gaming: Interacting with other players in online games.

    Internet Security

    • Threats:

      • Malware (viruses, worms, Trojan horses): Malicious software targeting system compromise.
      • Phishing: Fraudulent attempts to obtain sensitive data by impersonation.
      • Denial-of-service (DoS) attacks: Attempts to disrupt service by overwhelming traffic.
      • Spyware: Software tracking user activity without consent.
      • Identity theft: Stealing personal information for impersonation.

    • Security Measures:

      • Firewalls: Protecting networks from unauthorized access.
      • Anti-virus software: Detecting and removing malware.
      • Strong passwords: Creating complex and unique passwords for account security.
      • Two-factor authentication: Adding an extra layer of security requiring a second verification method.
      • Data encryption: Protecting sensitive data through encryption.
      • Secure websites (HTTPS): Using secure connections to prevent data interception and manipulation.

    Internet Impact on Society, Culture, and Commerce

    • Accessibility and Connectivity: Global information and resource access, connecting diverse backgrounds.
    • Communication and Collaboration: Facilitating instant global communication and collaboration.
    • Economic Growth and Opportunities: E-commerce, remote work, and broadened opportunities.
    • Social Implications: Influence on social interactions, identity, cultural exchange, and potential misinformation.
    • Education and Learning: Accessing information, online courses, and educational resources.
    • Globalization: Bridging cultural and geographical boundaries, fostering understanding.

    Other Important Concepts

    • Network topologies: Different network structures (e.g., bus, star, ring).
