Within the network covered, expensive devices such as laser printers or scanners can be shared. • The software and resources within the area of networks can be well organized and centrally managed. • Files can be shared on a central computer allowing data to be

this all network play a major role, for instance: if you look around you will find that everything is interconnected to its type to classified objects like: cell phone are connected to its signal providing tower or antenna and many more things.
