Difference between Grid Job and Grid Service

This is often a big point of confusion among grid newbies. Was for me too..here I clear it up for you::

A grid service is like a web service. Not much difference as such in concept. If you know what a web service is then you already know what a grid service is. Ill explain the use later (below)

A grid job is a normal computational cluster job. NO difference at all. It is called a grid job only because it runs in a grid as opposed to a cluster. Ok now this may bring up another fundamental question. How is a grid different from a cluster?!

From the grid job point of view, the only difference is that the grid job can be submitted to a grid using OGSA type services while a cluster job has to be scheduled, run etc manually or using a scheduler like SGE which manages the cluster.

Ok for the uninitiated, lets go one step deeper and simplify things furthermore....
