Explain the general structure of a typical process?
There are basically four main sections through which each of the process has to pass through.The universal algorithm is:-
Critical section:-
Consider a system consist of n processes P0 to Pn every process has a segment of code, called as critical section, in which the process perhaps changing common variables updating a table, writing a file and so on. Therefore critical section is that area of code in which the processors try to access the shared information. Therefore critical section occurs in the area where race condition occurs.
Entry section:-
Code just previous to the critical section is termed as the entry section. Every processor must request permission to enter into the critical section, the area of code which execute this request is called as the entry section.
Exit section:-
The code segment just subsequent to the critical section is termed as exit section.
Remainder section:-
The code remaining subsequent to the exit section is remainder section.
