Explain how a critical section avoids Race condition.
To prevent Race Condition, concurrent processes should be synchronized.
Data consistency needs that only one process must update the value of a data item at any time. It is ensured through the notion of a critical section. For data item d a critical section is a section of code, which can't be executed concurrently with itself or along with other critical sections for d. by considering a system of n processes as (P0, P1,..., Pn-1), all processes have a segment of code termed as a critical section, wherein the processes may be changing common variables and updating a table then writing a file, and so on. The significant feature of the system is that, while one process is executing into its critical section, no other process is to be permitted to execute into its critical section. Hence the execution of critical sections through the processes is equally exclusive in time.
