Question

_____ is a section of code within a process that requires access to shared resources and that must not be executed while another process is in a corresponding section of code.

A) Critical Section
B) Mutex Section
C) Atomic Section
D) Protected Section

Answer 1

A Critical Section is a section of code that needs exclusive access to shared resources and should not be executed concurrently with similar sections in other processes to prevent race conditions.

Step-by-step explanation:

The section of code within a process that requires access to shared resources and that must not be executed while another process is in a corresponding section of code is known as a Critical Section. The concept of a critical section is fundamental in concurrent programming, as it helps to avoid race conditions where multiple processes or threads access and manipulate shared data simultaneously, leading to unpredictable results. To manage access to the critical section, mechanisms such as mutexes, semaphores, and monitors are commonly used to ensure that only one process can enter the critical section at a time, thus maintaining data integrity.
