The above is correct. To be more specific, a CPU might need
to access some hardware device say I2c interface. Now if 2
processes in running state try to acquire and use I2c for
some data transfer, it might create problems, when one of
them hasn't finished its operations with the device. So
whenever some process has to make use of I2C it should lock
upon the mutex object for I2c device. And after the
operation gets finished it unlocks the mutex. Now some
other process can use I2c by mutex lock.
Similarly mutex object can be used to safegaurd some other
device resources.
