you mean computer networks that can be restricted within a single company floor to transmit information or the different internet networks each having different frequencies broadcast to connect your computer(s)?
Hosts on different networks communicate using a layer-3 address (layer 3 in the OSI reference model). In the networks used today, that would normally be an IP address.

There are millions of types of different networks in the world. These networks may be as simple as a computer network for example.
It depends on which type of network one is trying to find information for. Their Wikipedia page has a lot of information of different types of networks.
2. What is different between computer networks and internetwork?
No, a router connects 2 or more different networks. A modem just changes the signal type.
Two different networks are connected by a router. Switches are used to connect network devices within networks.
Dedicated networks for voice, video and computer data communications required a different type of device in order to access the network. Telephones, televisions, and computers used specific technologies and different dedicated network structures, to communicate. Converged networks are capable of delivering voice, video and data services over the same communication channel or network structure.
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.
Different networks are on different channels in different areas.
