RE: JES

Jes stands for Job entry subsystem.
it does 2 major things
------------------------------
1. manages batch jobs.
2. Routes output to the terminal nodes.
difference between the two
Jes2 is a De-centralized network.
Jes3 is Centralized.
In a centralised system, a group of computers are assigned jobs through a central computer.
In a decentralised system, each computer acts independently in its selection of jobs.
Also Note that, between Jes2 and Jes3 there is NO advantage of one over the other |
