WAN’s information rate is slow about a 10th LAN’s speed, since it requires increased distance and improved quantity of servers and terminals etc. Speeds of WAN ranges from couple of kilobits per second (Kbps) to megabits per second (Mbps). Propagation delay is one particular of the most significant difficulties faced right here. Devices utilised for transmission of data via WAN are: Optic wires, Microwaves and Satellites. Instance of a Switched WAN is the asynchronous transfer mode (ATM) network and Point-to-Point WAN is dial-up line that connects a residence personal computer to the Net.
Servers tend to be a lot more potent than workstations, though configurations are guided by requirements. For instance, a group of servers may possibly be situated in a safe region, away from humans, and only accessed through the network. In such circumstances, it would be widespread for the servers to operate with out a committed display or keyboard. Even so, the size and speed of the server’s processor(s), challenging drive, and main memory may possibly add dramatically to the expense of the system. On the other hand, a workstation might not want as much storage or functioning memory, but may call for an pricey display to accommodate the requirements of its user. Each and every personal computer on a network should be appropriately configured for its use.
