So we will discuss some special portals
-
Business Enterprise Intranets
-
Virtual University and Training
-
Science and Engineering Computing Environments
|
The latter include several projects aimed at harnessing the power of the web to do computing
-
These can be divided into those that harness web clients
-
And those than make networks of Web or distributed object servers
|
NPAC has focussed on networks of web servers and these fit the portal model well
|
However there is most computing power in collections of web clients
