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
