Description: A redirection table is used to manage the redirection of requests in a system. This mechanism is fundamental in the architecture of operating systems and other computing environments, where precise control over how resource and service requests are handled is required. In the context of communication between different execution modes, the redirection table acts as an intermediary that allows requests from user-mode processes to be properly directed to the system functions that operate in privileged mode. This is crucial for ensuring the security and stability of the system, as privileged mode has full access to hardware and system resources, while user mode is restricted to prevent malicious or erroneous processes from affecting the system as a whole. The redirection table, therefore, not only facilitates communication between these modes but also helps maintain a controlled and secure environment for application execution. Its design and operation are essential for the efficiency of the system, allowing for proper management of system calls and optimizing overall performance.
