Answer Posted / mohan reddy.k.v
When a memory is shared by more than one process, it must
be protected from simultanious access from many process,
This is called sycronization.In Linux there are many
sycronization techniques such as sephores,spinlocks,
per-cpu , mutex, seqlocks,atomic variables,rcu etc.
