What is the Central Server?


The Central Server, commonly referred to as Central, provides local area networking services to University faculty, departments and offices. It consists of a set of high-speed computers that stores office applications and data files shared by many different people in a department or work group.

The Central Server offers a reliable, cost-efficient alternative to installing a local file server at your location. The moderate monthly cost per user provides you with all the features, resources, and services you expect from a LAN, but without the worry and expense of having to manage your own.

A Citrix Server is used for fast remote access to all your Central files and Windows applications.
