Critical section in os: Here

Here, are four essential elements of the critical section: Entry Section: It is part of the process which decides the entry of a particular process. Critical Section: This part allows one process to enter and modify the shared variable. Learn about critical sections in programming, including their management, the critical section problem, and solutions like locks and test-and-set instructions. Critical Section: A critical section is a segment of code in which a process manipulates shared resources or variables. This is where the risk of interference from other processes is highest, and improper synchronization can lead to data corruption or unexpected behaviors. The critical section is a code segment where the shared variables can be accessed. An atomic action is required in a critical section i.e. only one process can execute in its critical section at a time. All the other processes have to wait to execute in their critical sections. A diagram that demonstrates the critical section is as follows − In the above diagram, the entry section handles the entry into the critical section. It acquires the resources needed for execution by the process ...
