Because of a staggering influx of Internet business, the network administrator’s task is to boost network performance and availability as much as possible. The company also wants a network design that’s easy to reconfigure and change because workgroups form and disband frequently, and their membership changes regularly. All computers must share sensitive data and control access to customer files and databases. Aside from the customer information and billing databases, which run on all servers, employees’ desktop computers must run standard word-processing and spreadsheet programs.
