What are Wide Area Networks (WANs)?
A Wide Area Network or a WAN connects offices that are geographically dispersed by linking computers in one location with those in another location. Different locations can be connected using standard dial up telephone lines; for faster, more secure connections, dedicated lines can be leased. Access Concentrators are network devices that allow organizations to connect many computers to multiple locations. Remote Access Servers (RAS) allow employees located outside of the company to access the company’s intranet.
