In the OSI model, the router is operated on the first three layers – physical, data link and network layer. This type of switch is also referred to as a network switch. If you’ve ever wondered "How does an Ethernet switch work? It's not a big deal when only a single PC or a few devices are broadcasting on the network; however, when multiple devices are active on the network on a 10/100Mbps hub, this can degrade performance. First, let's talk about the function an Ethernet switch performs on your network. The router will allow PCs and other connected devices to access the internet and other networks. The Ethernet switch can also be wired to the router via a cable that plugs into an Ethernet port, which allows you to access the internet through the modem. If you have only a few devices on your LAN, a hub may be a good choice for a central connection for your devices. The two pieces of equipment look similar and perform some similar functions, but each has its own distinct function to perform on a network. Since data packets contain the destination IP addresses of where they are headed, this enables routers and modems to communicate with each other using ICMP (Internet Control Message Protocol) to determine the most efficient path for transmitting data packets over the network to their destination point. A switch can't replace either a modem or a router, as these two devices do different things, but a switch can work together with modems and routers to make your network more efficient. The latter, can also provide routing functionality in addition to pure Layer 2 functionality. A router is a networking device that connects a local network to other local networks. The majority of routers have a single LAN port and single WAN port, while a switch will have multiple ports for different devices to communicate within the LAN such as PCs and printers. Thanks to the switch, these connected devices can share information and talk to each other, regardless of where they are in a building or on a campus. In addition to connecting multiple networks together, the router also allows networked devices and multiple users to access the Internet. When building a small business network, you will need one or more routers. A router works by connecting a network to another network via a modem. The most common connections involve LANs (Local Area Networks) or WANs (Wide Area Networks). More fundamentally, routers are layered in the standard OSI models, while switches operate at the data link layer (layer 2) unless they are multilayer switches. The typical ethernet switches, such as those used in broadband routers, support Gigabit Ethernet speed for every link, whereas the high-performance ones often found in a data center support 10 Gbps for every link.
