I have a late 2015 iMac 5K display and would like to know if I cause a late 2012 27 inch iMac as a second display? If so, what cable would I need to hook up to the old iMac to the new iMac?
iMac, OS X Yosemite (10.10.3)
1. Yes.
2. If you’ll be using Target Display mode, a Thunderbolt cable. If you’ll be using Virtual Network Computing, any network connection.

Niel,
Thanks for the quick reply and I hate to show my ignorance but what would be the difference between Target Display mode and Virtual Network Computing. I think my answer is to be in the Target Display mode but just want to be sure.
Thanks!
Target Display mode uses a video connection and is faster, but requires that the computer being used as a display has specific hardware, and isn’t usable on nearly as many computers.
Virtual Network Computing sends the data over an existing network connection.

VNC allows you to see and control the other computer. It does NOT allow the other computer to be a secondary screen for the original computer.
So if you want to use an iMac as a secondary monitor for your 2015 iMac, that other iMac has to meet the criteria defined in Use your iMac as a display with Target Display Mode - Apple Support
TThanks to both & I think I have what I need.
Can I use another iMac as a display on a late-2015 27" iMac?
