Description: Context loading is a fundamental operation in process and thread management within an operating system. It refers to the process of loading the state of a process or thread from secondary memory (such as a hard drive) into main memory (RAM) so that it can be executed by the CPU. This state includes registers, program counters, and other necessary data for the process to continue its execution from the point it was interrupted. In many modern computer architectures, context loading is performed in an optimized manner to minimize CPU idle time. Context loading is crucial in multitasking systems, where multiple processes compete for system resources. By allowing the CPU to switch quickly between different tasks, overall system efficiency is improved, and a smoother user experience is provided. Additionally, context loading is an essential component in implementing virtualization techniques and memory management, as it allows operating systems to maintain isolation and security between different processes.
