broad area (i.e. any network whose communication links cross metropolitan, regional, or national boundaries).

A WAN is a network that uses routers and public communication links.

MAN-Metropolitan Area NetworkA MAN is a network that connects two or more

local area networks or campus area networks together but does not extend beyond the boundaries of the immediate town/city. Routers, switches and hubs are connected to create a metropolitan area network.

Networking provides social contact and stimulation.

A job may be specifically created for you based on an employer’s requirement.
