2. Network switch - Wikipedia

   en.wikipedia.org/wiki/Network_switch

   A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches.

3. Forwarding information base - Wikipedia

   en.wikipedia.org/wiki/Forwarding_information_base

   The role of an Ethernet switch is to forward Ethernet frames from one port to another. The presence of a FIB is one attribute that separates a switch from a hub. Without a functional FIB, all frames received by a network switch would be echoed back out to all other ports, much like an Ethernet hub.

4. Ethernet hub - Wikipedia

   en.wikipedia.org/wiki/Ethernet_hub

   Historically, the main reason for purchasing hubs rather than switches was their price. By the early 2000s, there was little price difference between a hub and a low-end switch. [11] Hubs can still be useful in special circumstances: For inserting a protocol analyzer into a network connection, a hub is an alternative to a network tap or port ...

5. Router (computing) - Wikipedia

   en.wikipedia.org/wiki/Router_(computing)

   When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry.

6. Inter-network processors - Wikipedia

   en.wikipedia.org/wiki/Inter-network_processors

   Most commonly used inter-network processors are switches, bridges, hubs, routers and gateways. Switches act as interfaces for communication between telecommunications circuits in a networked environment. In addition, most modern switches have integrated network managing capabilities and may operate on numerous layers of the OSI reference model ...
