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. If you are in the market for one of them specifically, read labels at the store or ask the seller if you are buying online. Many people will have a hard time identifying a network switch from a hub. You can quickly identify these devices inside a network as the rectangular box-shaped device where all the LAN cables are connected. Both provide multiple ports for Ethernet (LAN) cables and options for other wired connections such as BNC and fiber optics. Hub: Understanding the Similarities and DifferencesĪn Ethernet switch and a hub have many similarities. However, an Ethernet switch and a hub differ in some ways, which we’ll discuss below.Įthernet switch vs. These network devices allow several computers to connect to a central station, providing a network connection. However, since each device will have limited Ethernet ports, you’ll need a network switch or a hub. The most reliable way to connect to a network is through wires, such as an Ethernet cable. It allows us to transfer data from one device to another, ultimately providing our LAN and WAN. The ability to network or connect to different devices is one of the biggest technological advancements of modern society.
