Are spin waits, spin loop and busy spin a different name for the same situation?

I read different threads and they all seem related to a loop that is "busy" checking for the availability of a resource.

Busy Spin

A technique which is used in a way that it loop is running until other thread have to complete his work.

Spin Wait

A spin wait that you have to wait until condition for thread is true.

Spin Loop

Spin loop is also similar to both of above busy spin and wait spin. It means that threads have to wait for other thread for completing his work.

By the way I think these terms can also use interchangeably. Precisely these are the same terms.
