1.5 Network Topologies and Layers

Overview of Learning
  • Ring, Star and Mesh PHYSICAL topologies (what does it look like - shape/size)
  • Ring, Star and LOGICAL topologies (What METHOD does the LAN use to transmit packets [Ethernet or Token Ring])
  • Wifi:
    • frequency and channels
    • encryption
  • The concept of layers in the TCP/IP protocol
      Application Layer
