Redhat server and client
 

I have a Redhat entreprise installation disc , this is for server installation ,can advise if Redhat have a disc for client installation ? or they are the same set of disc ?

Thanks.

I think there are no client side OS in Redhat Enterprise Linux its only dedicate Server OS, if you wish to use Linux in client side fedora, Ubuntu, Debian, Slackware etc.. are may be better choice.

RedHat does (did?) have wkstn discs, although these days you may have all/enough on the DVD to install the basics, then get the rest from the repos.
I'm assuming you've paid for this?
If not, no updates, no support from RH; use Centos instead.
