Detailed explanation-1: -WAN is widely used in long-distance communication systems. It covers bigger areas i.e right from a state to a country. Therefore the geographical area it covers is from 100 to several 1000 km.
Detailed explanation-2: -A wide area network (WAN) is any network that extends over a large geographic area, usually connecting multiple local area networks (LANs).
Detailed explanation-3: -LANs can be distinguished from other networks because of their short distance. The total coverage may be from 1 km to 10 kms. The data transmission speed of LANs is much higher than in other types of networks. When a WANs works at a speed of 1 mbps, LANs can transmit data at a speed of 1-10 mbps.
Detailed explanation-4: -LAN does not cover a large geographic area. LAN networks are connected with each other to form WAN, that is, Wide Area Network, which spans over a large geographical area.
