 As always, before we will consider something synchronization related, we will try to know what is `synchronization primitive` in general. Actually, synchronization primitive is a software mechanism which provides ablility to two or more [parallel](https://en.wikipedia.org/wiki/Parallel_computing) processes or threads to not execute simultaneously one the same segment of a code. For example let's look on the following piece of code:
