Explain why Windows, Linux, and Solaris implement multiple locking mechanisms.

Describe the circumstances under which they use spin-locks, mutex locks, semaphores, adaptive mutex locks, and condition variables.

In each case, explain why the mechanism is needed.

I have already posted this question once before and there is an answer on the internet for this question. Please do not post that paragraph I need something a little more in depth then that. I am just wondering what Windows Linux and Solaris use do they use all these (spin-locks, mutex locks, semaphores, adaptive mutex locks, and condition variables. ) or not and what is their purpse in each operating system.

Thank you so much for your time I really appreciate it.
