w to capitalize on the advantages of end-user computing while encouraging data-sharing and ensuring integrity and confidentiality.
Using personal computers and associated peripherals, companies have been able to create local area networks (LANs) within their offices; wide area networks (WANs) have been implemented when companies link computer systems across wide geographic areas. These networks make it possible for users in one location to access and modify data created in another location. Confidentiality is ensured since the data is maintained within a company-only network, and there can be significant improvements in productivity. The following diagram provides a sample network layout for a company with offices in different locations which needs to transfer multimedia information across a wide variety of locations; such geographic considerations are key in a business world which is increasingly global:
In the above example, the local loop would most likely be a broadband network. The broadband network concept came from the fact that a wide range o
