The Ethernet HubĪn Ethernet hub or network hub is a simple networking device that extends a network by providing multiple Ethernet ports. You should opt for a network switch if you are designing a network for home, school, office, or business. For these reasons, a switch is used on almost every network that needs more Ethernet ports than a router can provide.
Although this isn’t necessarily true, they have some very good reasons to believe so.Īs a full-duplex network bridge that operates on the data link layer and sometimes the network layer, a switch provides better speed, privacy, security, and versatility when compared to a hub. Many would agree that network switches are superior in every way to a hub. So, aside from a MAC address table, these layer 3 switches will also have access to an IP routing table, allowing redirection of data through IP addresses assigned within the network.
Some network switches can operate on both layer 2 and layer 3 (network layer) of the OSI model.
