Kontekstivahetusega

Kontekstivahetusega, also known as context switching, refers to the process by which a computer's central processing unit (CPU) shifts its focus from one task to another. This is a fundamental aspect of multitasking in operating systems, allowing multiple processes to be executed concurrently. Context switching involves saving the state of the current task, including the CPU registers and program counter, and loading the state of the next task to be executed. This process ensures that the CPU can efficiently manage and switch between different tasks, optimizing resource utilization and system performance. However, frequent context switching can lead to overhead, as the CPU spends time saving and loading states rather than executing instructions. This can potentially degrade performance, especially in systems with a high number of tasks or processes. To mitigate this, modern operating systems employ various techniques, such as time slicing and priority scheduling, to balance the need for responsiveness with the efficiency of context switching.
