Description: Thread context switching is the process of saving the state of a thread so that it can be resumed later. This process is fundamental in multitasking operating systems, where multiple threads can run on a single CPU core. During context switching, critical information such as the program counter, registers, and stack state of the current thread is saved. This allows the operating system to interrupt a running thread and replace it with another, optimizing CPU usage and improving overall system efficiency. Context switching can be costly in terms of time, as it involves manipulating data structures and updating registers, which can impact performance if done too frequently. However, it is essential for ensuring that threads can effectively share resources and that multitasking applications run smoothly. In this sense, context switching is a key component in CPU scheduling, as it allows schedulers to determine which thread should run at any given moment, balancing workload and responding to user and application needs.
