TYPES OF NETWORK
There are different types of networks. Common types of networks are: WAN and LAN. There are other types of networks as well: SAN, MAN, BAN, IAN and others. Each network type helps us understand the purpose, design goals, and scale of the network. For example if we say a network is a LAN, we can assume it is a local network, probably in one building or in a reasonably restricted area. We might make an assumption that a LAN has a certain number of devices connected to it. However, if we say a network is a WAN, we might assume it is much larger, and designed to accommodate a much, much larger number of devices.
