    Study Notes

    Internet Structure and Organizations

    • IETF (Internet Engineering Task Force): Develops and promotes voluntary internet standards.
    • ICANN (Internet Corporation for Assigned Names and Numbers): Coordinates the assignment of domain names and IP addresses.
    • IAB (Internet Architecture Board): Provides architectural oversight for the internet.

    Intranets and Extranets

    • Intranet: A secure internal network owned by an organization, only accessible to authorized users.
    • Extranet: Access point allowing authorized external users to interact with an organization's data securely.

    Internet Access Technologies

    • Home users commonly connect through options such as broadband cable, DSL, wireless WANs, and mobile services.
    • Organizations typically require faster connections for functionalities like VoIP, video conferencing, and data storage.
    • Business-class connections may include DSL, leased lines, and Metro Ethernet.

    Converged Networks

    • Converged data networks allow simultaneous transmission of data, voice, and video over a single infrastructure.
    • A unified set of rules and standards governs the infrastructure for these services.

    Reliable Networks: Network Architecture

    • Fault Tolerance: Networks are designed to minimize the impact of failures by ensuring multiple paths for data transmission.
    • Scalability: Ability to expand without degrading performance for existing services, supported by adherence to standards and protocols.
    • Quality of Service (QoS): Mechanism to ensure reliable delivery of voice and video content through bandwidth management.
    • Security: Encompasses both network infrastructure security (preventing unauthorized access) and information security (ensuring data confidentiality and integrity).

    Network Security Goals

    • Confidentiality: Ensures that only intended recipients can access data.
    • Integrity: Guarantees that data remains unaltered during transmission.
    • Availability: Provides timely and reliable access to data for authorized users.
    • Organizations must adapt to trends such as Bring Your Own Device (BYOD), online collaboration, video communications, and cloud computing.
    • Cloud Computing Types:
      • Public Clouds: Open to general public, often pay-per-use.
      • Private Clouds: Designed for specific organizations (e.g., government).
      • Hybrid Clouds: Combine elements of public and private clouds.
      • Custom Clouds: Tailored to specific industry needs, can be public or private.

    Smart Home Technology

    • Increasing integration of technology in everyday appliances to improve interconnectivity, such as smart ovens that sync with calendars.

    Powerline Networking

    • Allows devices to connect to a LAN using electrical outlets, bypassing the need for data cables or Wi-Fi.
    • Effective solution for areas where wireless coverage is weak or non-existent.
