A File Server is a computer attached to a network that has 
the primary purpose of providing a location for the shared 
storage of information (such as documents, sound files, 
photographs, movies, images, databases, et cetera) that can 
be accessed by the workstations that are attached to the 
network. As distinguished from Timesharing or a Mainframe 
(where a central computer provides calculation resources 
for "dumb" terminals) a File Server is designed primarily 
to enable the rapid storage and retrieval of data where the 
heavy computation is provided by the workstations.
