  1. Networking Hardware

  2. Hubs – How they work • Hubs send data from one computer to all other computers on the network. They are low-cost and low-function and typically operate at Layer 1 of the OSI model.

  3. Hubs – Diagram Hub

  4. Switches – How they work • Switches are devices that relay traffic by using a Layer 2 address. They usually contain software that supports the building of routing tables.

  5. Switches– Diagram Server Switch

  6. Routers – How they work • Routers are specialized hardware devices with a tailored operating system. They are designed to relay packets between nodes in a data network. Routers operate at Layer 3 of the OSI model.

  8. Bridges – How they work • Bridges perform similar operations to switches. The key difference is that bridges are associated with a LAN device that uses a MAC address for routing.

  9. Bridges – Diagram Bridge Collision Domain

  10. Gateways – How they work • Gateways are network nodes equipped for interfacing with another network that uses different protocols. They operate at Level 3 of the OSI model.

  12. Firewalls – How they work • Firewalls are devices used to protect a more secure network from a less secure network. Firewalls generally protect your internal LAN from the Internet. Firewalls generally operate at Layers 3 and 4 of the OSI model.

  14. Wireless Access Points – How they work • Wireless Access Points (WAPs) are devices that allow wireless devices to connect to a wired network using Wi-Fi, Bluetooth, or other related standards.
