    Study Notes

    Protocol Elements

    • Data Format: Defines the structure or format of the data being communicated.
    • Semantics: Refers to the meaning or interpretation of the data being communicated.

    Wired vs. Mobile Networks

    • Wired Networks: Fixed, physical connections.
    • Mobile Networks: Use wireless signals for communication.
    • Common Mobile Network Issue: Interference and signal loss due to physical obstructions.

    Protocol Stacks

    • A protocol stack is a layered model that organizes various protocols used for network communication.

    Connection-Oriented & Connectionless Services

    • Connection-Oriented: Establish a dedicated connection before data transmission.
    • Connectionless: Data packets are sent independently without prior connection setup.

    Network Neutrality

    • Network neutrality ensures all data traffic is treated equally by internet service providers.

    Network Service Characteristics

    • Connection-Oriented: Ensures reliable data delivery with acknowledgment of receipt.
    • Connectionless: Does not guarantee delivery or acknowledge receipt, known for its speed.
    • Reliable Services: Offer error detection and correction, ensuring data integrity.

    Network Models

    • Connectionless Service Model: Emphasizes speed over reliability, data is sent in packets without a guaranteed connection.

    Network Categories

    • Personal Area Network (PAN): Connects devices within a short range, e.g., Bluetooth.

    Network Switching

    • Store-and-Forward Switching: Packets are temporarily stored before being forwarded.

    Wide Area Networks (WAN)

    • Wide Area Networks: Cover geographically large areas.

    Network Categories

    • Home Network Categories: Wired, Wireless, and Hybrid.
    • Metropolitan Area Network (MAN): Covers a city or campus.

    Network Topologies

    • Fully Connected Mesh Topology: Every device has a direct link to every other device.
    • Disadvantage of Fully Connected Mesh Topology: Expensive due to numerous connections.
    • Wireless Network Configuration: Individual mobile computers can connect wirelessly.
    • Mesh Topology Advantages: Offers redundancy and fault tolerance, as data can be routed through multiple paths if a connection fails.

    Internet Characteristics

    • The internet uses a hierarchical structure with multiple connected networks.

    Topology Disadvantages

    • Bus Topology: Susceptible to data collisions, a single fault can disrupt the network.
    • Star Topology: A fault in the central device can affect the entire network.

    Ring Topology

    • Ring Topology: Commonly used for fiber optic networks, data travels in a loop from device to device.

    Mesh Topology Characteristics

    • Offers high reliability through multiple paths, but requires complex configuration.

    Choosing a Network Topology

    • Future Growth: Scalability, expandability, and ease of modification are key considerations when choosing a topology.

    Commercial Network Cabling

    • Twisted-Pair Cable: Commonly used in commercial organizations for star topologies due to its cost-effectiveness.

    Network Devices

    • Hub: Simple device that forwards data to all connected devices.
    • Router: Connects different LANs or WANs, directs traffic based on network addresses.

    OSI Model Layers

    • Physical Layer: Deals with the physical transmission of bits.
    • Data Link Layer: Responsible for error detection and correction.

    Hub vs. Switch

    • Switch: Offers more intelligent data forwarding by using MAC addresses to direct traffic to specific destinations.

    OSI Model Layers

    • Presentation Layer: Not part of the OSI model.

    Network Extension Devices

    • Repeater: Extends network range without filtering capability, amplifies signals.

    Transport Layer

    • Transport Layer Function: Responsible for end-to-end data delivery, segmentation, and error checking.
