    OSI and TCP/IP Models

    • TCP/IP Model Layers: Specific layers are identified and used in data transfer processes.
    • OSI Model Layers: Relevant OSI layers are discussed, but their mapping to TCP/IP might not all be explicit layers.
    • PDU (Protocol Data Unit): Data as it travels between protocols and layers.
    • MAC addresses: Unique hardware addresses for network devices
    • IP addresses: Unique logical addresses for network devices
    • Subnet Masks: Needed to determine network and host part of the IP address.

    Network Cabling and Wireless

    • UTP (Unshielded Twisted Pair) cabling interference: Interference sources identified like proximity to electrical equipment, proximity to fluorescent lights.

    Troubleshooting and Diagnostics

    • ARP cache: Needed for resolving IP addresses to MAC addresses.
    • Protocol analyzer: Device for observing and analyzing network traffic.
    • Tracert: Tool to trace route from source to destination.

    Other key concepts not listed
