Routers and switches are networking devices that connect computers and networks, but they operate at different layers and have different functions. Routers operate at the network layer (layer 3) and use IP addresses to direct traffic between networks, while switches operate at the data link layer (layer 2) and use MAC addresses to direct traffic within a local area network. Some key differences are that routers can perform tasks like network address translation, have fewer ports, and take longer for routing decisions than switches.
Router vs switch
- 1. Router vs Switch Routers and switches are both computer networking devices. They allow one or more computers to be connected to other computers, networked devices, or to other networks. However, the functions of a hub, switch and router are quite different, even if at times they are integrated into a single device. Routers connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router. The term layer 3 switches often is used interchangeably with router, but switch is really a general term without a rigorous technical definition. In marketing usage, it is generally optimized for Ethernet LAN interfaces and may not have other physical interface types.
