• What is LAN?
A LAN (Local Area Network) is a network confined to limited space, such as a building or floor. If you have multiple computers in your home or office, you have a Local Area Network (LAN). A LAN is usually under the control of the company or entity that requires its use. A LAN can be tiny or huge, with one or thousands of users and devices in an office or school.
A LAN connects devices in a single, constrained area, regardless of size. A WAN or MAN, on the other hand, covers a greater geographic area. In addition, some WANs and MANs link several LANs.
• What is WAN?
A WAN (Wide Area Network) is a network mostly provided by a third-party Internet Service Provider that connects many local area networks (LANs) geographically separated. ONE EXAMPLE IS an MPLS Network (offered by a telecommunications provider) connecting company headquarters in New York, Boston, and Los Angeles. The Internet is the most significant WAN.
