Devices & Protocols in Relation to OSI Model (part 1)

How the OSI Model applies to different devices and protocols This lesson covers how different protocols and devices relate to the OSI Model, specifically focusing on:
  1. MAC addresses: Layer 2 (data link), physical address
  2. IP addresses: Layer 3 (network layer), logical address mapped to physical
  3. EUI 64: Layer 2 (data link) IPv6 global unicast
  4. Frames: Layer 2, protocol delivery unit, segment of data with a beginning and ending.
  5. Packets: Layer 3, Protocol delivery unit, segment of duty
  6. Switch: Layer 2, data link. Map to MAC address
  7. Router: Layer 3 Network, a type 3 switch, moves data across networks.
  8. Multi-layer switch: Layers 2/3, performs at multiple levels.
  9. Hubs: Layer 2, data link, passes information to everyone
  10. Encryption device: layer 6, presentation. Formats data.
  11. Cable: layer 1, physical device.
  12. Network Interface Card (NIC): Layer 1, physical.
  13. Bridge: Layer 2. Data link device. Point to point.
