semaphore : a method for restricting access to a shared resource. Usually, this is a counter that counts the number of current concurrent accesses.
binary semaphore : better known as a mutex. The same as a normal semaphore, except that only one entity is allowed access to the shared resource at a time (so, it has only two valid values : "locked" and "unlocked"). A mutex is often used to protect critical sections (of code).
split binary semaphore : a variant of the binary semaphore, used for conditional critical sections. It is actually a set of n binary semaphores of which only one can be "locked" at a time.
