: -The goal is to make all programs, equipments, especially data available to anyone on the network without regard to the physical location of the resources and the user printer, scanners which are expensive resources can be shared among many computer s. That is printer is installed one dingle machine which is networked and used by all machine connected to that network.
: - A second goal is to have alternative source of supply for e.g. all files could be replicated on two or three machines, so if one of them is unavailable due to say hardware failures the other copies could be used and hence increase the reliability.
: - Small computers have much better price/ performance ratio than larger ones. Main frames are ten times faster than personal computers, but their cost is thousand times more than personal computers
: - It is the ability to increase system performance gradually as the workload grows just by adding processors.
Communication medium among employees
: - A computer networks provides a powerful communication among the widely separated employees. Using a network it is easy for two or more people who live for apart write a report together.
