Diff between grid computing & client server computing

[Nian Xin Fun]

Hi Mr Toh

What is the difference between grid computing and client serve computing?

Also in demystified, another form of distributed system is inter-organisational system. Is this an example of client server or what?

Thank you

Grid computing is based on client-server technology (like practically everything else on the Internet).  Machines are hooked up together in a managed  distributed network and any machine can be used by subscribers to do specific tasks.  It is a kind of supercomputer comprising a communal network of shared machines and often used by organisations with very intense computing requirements, eg. data visualisation, computer animations, astronomy, weather etc.  Subscribers will usually submit a "job" to the grid and leave it to the system to distribute computation responsibilities amongst all the computers in the network.  Grid computing is an application-specific form of cloud computing, which is more service-oriented than application-oriented.

Inter-organisational systems (IOS) refer to any information system that link information systems belonging to different companies/organisations together.  Supply chain systems (SCMs) are the best examples of IOS.  IOS that are based on the Internet (eg. web-based SCMs) are generally based on the client-server architecture.  And yes, these are all distributed systems.
