Answer / krishna akkulu

Using a mutex is more expensive in terms of CPU
utilization, but mutexes may be shared outside the
processes boundaries.

A critical section object provides synchronization similar
to that provided by a mutex object, except that a critical
section can be used only by the threads of a single
process.

Event, mutex, and semaphore objects can also be used in a
single-process application, but critical section objects
provide a slightly faster, more efficient mechanism for
mutual-exclusion

Answer / xxxx

Supports synchronization by which we can provide controlled
access to the shared resource. At a time, only one process
can access the shared resource by using mutex n critical
section.
