Case Study: The ELCO Family

 This opening case study focuses on the
 concept of setting up a home network
 that would link together four computers,
 as well as printers and a DSL Internet
 Connection. Students are asked to write
 a short document describing the
 advantages of a home network and
 possibly prepare a drawing of what the
 network would look like.
