5.1 Identify the fundamental principles of networks

  • Describe basic networking concepts

    • Addressing

    • Bandwidth

    • Status indicators

    • Protocols (e.g. TCP / IP including IP, classful subnet, IPX / SPX including NWLINK, NETBEUI / NETBIOS)

    • Full-duplex, half-duplex

    • Cabling (e.g. twisted pair, coaxial cable, fiber optic, RS-232, USB, IEEE 1394 / Firewire)

    • Networking models including peer-to-peer and client / server

  • Identify names, purposes and characteristics of the common network cables

    • Plenum / PVC
