Thin Client/Server Technology (TCST)
Thin client server technology (TCST) came about as a result of
the constant need to upgrade PC desktop along with the high cost of maintenance
and manpower that is needed to ensure a continuous flow of information.
Although the desktop PC is a useful tool that enables its users to increase
their productivity, there are many who believe that it has become rather
complicated and bloated , hence the name ‘fat client’.
The thin client is a simple desktop device that consists of a
processor, some RAM and an input device with a monitor. It comes without a hard
drive, CD-ROM or expansion slots and relies on the server for processing power
and loading of applications. Network
computers and Windows-based terminals
(WBTs) are two types of thin clients that are currently available.
Some of the advantages that the TCST has to offer the
healthcare industry include:
There are however some disadvantages
with TCST are:
The lack of local storage means that remote users cannot download files in
order to work offline.
Software for thin clients has not yet matured, so it is hard to gauge their
Network requirements for effective information transfer with thin client server
networks (usually that of a T-1 bandwidth) are more than that found in majority
of the healthcare networks available.
