The Internet

Part of the Computers and Medicine book series (C+M)


In Chapter 4, it was noted that most of the early information retrieval (IR) systems resided on large centralized computers and were accessed via terminals, connected either directly or via modem. This was followed by CD-ROM systems, which moved the database to the individual machine or local area network, allowing a better user interface and eliminating the distraction of per-minute charges. More recently, databases have moved back to larger machines but in a form much different from the original centralized systems. These new systems run on computer networks, whose client-server capabilities make possible a whole new world of IR systems.
