Mutual Exclusion:

1. Lock and unlock operations are always performed by the same thread.
2. Thread blocked on semaphore cannot be awakened by a signal.

Synchronization:

1. Lock and unlock operations performed by different threads.
2. Threads blocked on a synchronization semaphore have three options:
a) Signals can be caught and handled.
b) Signals can be deferred until the semaphore operation is complete.
c) Signals can be handled as though the code were unsemaphored.

As I understand it, and I'm just revising it, Conditional synchronisation is the mechanism that allows one to achieve mutual exclusion in a program.
