Three devices include, routers, switches and modems. Routers are used both in home and business environments they have many functions but their primary function is to route data and is typically the center of a home network many home routers include functions such as firewalls and DHCP some higher end models support VLANS. A switch is a device that allows multiple devices to connect to the same router/switch/computer port by sorting out data and sending to a specific connected device. A modem is the device that connects a local network to the ISPs many of which also serve as routers in a home or small business network.
