ALAN provides its users with several advantages. It is an effective means of en-
abling a variety of users to share information technology resources as well as infor-
mation. It tends to be less costly than standalone systems. A well-designed LAN normally improves the productivity of employees; the LAN not only provides easier access to the needed services but also allows the employees and managers to com-
municate more easily and quickly with each other. Finally, a LAN is quite flexible, since workstations can easily be added or removed.
