Front 1

Advantages of Local Area Networks

Back 1

Ability to share hardware and software resources.
Individual workstation might survive network failure.
Component and system evolution are possible.
Support for heterogeneous forms of hardware and software.
Access to other LANs and WANs (Figure 7-1).
Private ownership.
Secure transfers at high speeds with low error rates.

Front 2

Disadvantages of Local Area Networks

Back 2

Equipment and support can be costly.
Level of maintenance continues to grow.
Private ownership.
Some types of hardware may not interoperate.
Just because a LAN can support two different kinds of packages does not mean their data can interchange easily.
A LAN is only as strong as it weakest link, and there are many links.
