Question 5O out of 1 pointsA What are the relevent details of a trap?SelectedThe trap is often an instruction that helps move from user-mode to kernel-mode by raising the privilege level to execute privileged operations. Upon returning, the privileges are reduced to theirAnswers:original level.ResponseFeedback:User privilege in the system has no impact on how processes are treated in the OS. All system calls are treated the same regardless of how important the program, although some kernelprocesses may already be in the privileged state for the majority of their time on the CPU.

Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.
