Connecting different networks requires a router
The purpose of a router is to connect dissimilar networks.
A layer 3 device such as a router.
For two or more connected networks you can use a bridgeto connect them all together.It depends on the two networks. A bridge can only connect two networks of the same type (eg Ethernet or Token-Ring), that also use the same layer 3 network address (eg IP subnet or IPX network #, or AppleTalk network #).A "gateway" device can connect two dissimilar types that share a network address, and a router can connect two networks of different network addresses whether or not they have the same network type.
For a small LAN network, a switch is best. To connect two or more LAN networks, a router is required. (2) From Jean Andrews CompTIA A+ sixth edition (page #852): You can use a crossover cable to connect to computers without a switch or hub making it the simplest network of all. For two or more you will need a switch, hub, or router.
Switch for small LAN, Router for two or more
A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet.
Router.
The most common types of bridges are the Beam and Arch Bridges.

A router is layer 3 device whose each port is a separate broadcast and collision domain. router is a device that makes communication possible between two or more networks.
