A minimum of _____ variable(s) is required to be shared between processes to solve the critical section - Brainly.in? ›
Therefore, the answer is B. two. To address the critical section problem, at least one shared variable is necessary for processes to coordinate access to their critical sections. A minimum of two variable(s) is required to be shared between processes to solve the critical section problem.
What minimum of variable s is required to be shared between processes to solve the critical section problem? ›"Two" is the correct answer to this question:
It implies the one process has to perform its essential section in a group of communicating systems at that particular time. It uses semaphore, in which it uses two integer variables to solve this problem.
After a process has made a request to access its critical section and before that request is approved, a limit on the number of times other processes are allowed to enter their critical sections must exist. Hence the correct answer is Mutual Exclusion, Progress, and Bounded Waiting.
How many processes are shared between variables under critical section? ›The critical section is a code segment that allows access to the shared variables. In a critical section, an atomic action is needed, which means that only one process can execute in its critical part at a time.
What are the conditions to solve the critical section problem? ›Solution to the Critical Section Problem
- Mutual Exclusion. Mutual exclusion implies that only one process can be inside the critical section at any time. ...
- Progress. Progress means that if a process is not using the critical section, then it should not stop any other process from accessing it. ...
- Bounded Waiting.

Solutions to the critical section problem. Any solution to the critical section problem must satisfy the following requirements: Mutual exclusion: When one process is executing in its critical section, no other process is allowed to execute in its critical section.
What is the solution to a 2 process critical section problem? ›Shared variables are created and initialized before either process starts. The shared variables flag[0] and flag[1] are initialized to FALSE because neither process is yet interested in the critical section.
What is critical section problem what are the requirements that critical section problem must satisfy for its solution? ›The critical section problem is used to design a set of protocols which can ensure that the Race condition among the processes will never arise. In order to synchronize the cooperative processes, our main task is to solve the critical section problem.
What is the solution to a two process critical section problem? ›Peterson's Algorithm: Peterson's Algorithm is a solution to the Critical Section Problem in os for two processes. It uses shared memory and atomic instructions (such as test-and-set) to ensure that only one process can enter the critical section at a time.
How can the critical section problem be solved in bakery algorithm? ›Bakery Algorithm is an algorithm that basically works as a generalized solution for the critical section problem, that means for N processes. The essential concept that it follows is that each process is given a variable that decides when the process will be allowed to execute its critical section.
Which uses atomic functions like wait () and signal? ›
Semaphores are two-field data types, one of which is a non-negative type of integer S.V and the other is a set of processes in a queue S.L. It is used to address critical section problems by using two atomic operations, wait and signal, to synchronize processes in this.
Which of these is a synchronisation tool? ›Explanation: Semaphore is a synchronization tool. Semaphore is a mechanism which synchronizes or controls access of threads on critical resources.
