Local area networks (LANs) are designed for connecting devices within a limited area like an office, building, or campus. So, if your business operates in a single location, a LAN is best for high-speed connectivity across local devices.
Wide area networks (WANs) are ideal for connecting offices, data centers, or branches across cities, states, or even countries. If you require access to cloud services or external networks, WANs provide connectivity to the internet or external servers.
In a nutshell, if your business is small and operates in a single location, a LAN is sufficient. For larger businesses with distributed teams or locations, a WAN is a better fit. Many businesses also use a combination of both, with a LAN for local operations and a WAN for broader connectivity.
