A client/server
system ,
according
to
Whitten
[4],
is
a
solution
in
which the
presentation,
presentation
logic,
application logic, data manipulation, and data layers are
distributed between client PCs and one or more servers. Client may be thin and fat.
1. A thin client
is PC with low specification in terms of processor speed and memory
because
it only shows user
interface to the end-user.
2. A
fat
client is
PC
with
higher
specification
in
terms
of
processor
speed
and
memory
Client/Server system has come up with many possibilities such as: distributed
presentation, distributed data, and distributed data and application. However, in this book,
we would like to look closer on distributed presentation only.
2.1.6.4 Client/Server – distributed
presentation
A distributed
presentation
client/server
system
is
a
kind
of
technology
that
presentation
and
presentation
logic
are
located on the client machine. However, the
application logic, data manipulation, and data layers remain on the server (frequently a
mainframe).
