Can you use the OS disk multiple times?

I have googled this multiple times, before being confused in a flurry of acronyms.
I am wondering if you can use the disk to install windows 8 to separate computers without having to buy another copy. Thanks!

The disk you can use wherever you please. What MS is really concerned about is how the LICENSE KEY is used. The same key can re-activate the same PC as many times as needed. It can not be used on more than one PC at the same time. It may be transferable (this will deactivate it on one PC when it's activated on a newer one) if it's a retail copy, but not an OEM copy.
