Wired networks are networks that use a (CAT or Fiber Optic) cable
connection that goes from a computer on the network to a
device such as a switch, hub or directly to the router.
A server based wireless network have a server
computer on the network that is used to control access to
files and printing resources.
The advantage to this
type of network is that you can get greater consistent
transmission speeds than wireless and it
is harder for hackers to breach.
The disadvantage is cost. It cost
more than wireless network because you have to purchase the
cable, switch.
