What is the primary difference between WAN and LAN?
The primary difference between WAN (Wide Area Network) and LAN (Local Area Network) lies in their geographical coverage and usage. A LAN is typically confined to a small geographical area, such as a home, office, or campus, and is used for connecting computers and devices within that limited space. In contrast, a WAN covers a much larger area and can connect multiple LANs, spanning from cities to countries. This larger range allows organizations to link their remote offices or branches efficiently.
Additionally, LANs generally provide higher speeds and lower latency because the devices are physically close to each other. On the other hand, WANs often experience higher latency and lower speeds due to the longer distances data must travel and the involvement of multiple networking equipment. Both types of networks serve unique purposes depending on the needs of the user, whether that be local resource sharing or access to broader networks.
What are the common use cases for WAN and LAN?
LANs are commonly used in environments where many devices need to build a network quickly and easily.
