<prompt> Hlalosa hore na phetoho ea moelelo ke engnan  <response>: Instruction in English: Define what is a context switch . Response in English: A context switch is the process by which a computer operating system or a hardware interrupt changes the currently executing task or thread, and replaces it with another. This process takes place many times a second in a multitasking operating system, in order to give the appearance that multiple tasks or threads are being executed simultaneously. During a context switch, the operating system saves the state of the current task, such as its CPU registers, program counter, and memory management information, and loads the saved state of the new task to be executed. Context switches are an essential part of multitasking and can impact the efficiency and performance of the system, as they involve overhead and processing time. .

Tsebetso ena e etsahala hangata ka motsotsoana tsebetsong ea tsebetso e mengata, e le ho fana ka ponahalo ea hore mesebetsi e mengata kapa likhoele li ntse li etsoa ka nako e le ngoe. Nakong ea phetoho ea maemo, sistimi e sebetsang e boloka boemo ba mosebetsi oa hajoale, joalo ka lirejistara tsa eona tsa CPU, khamera ea lenaneo, le tlhaiso-leseling ea taolo ea memori, me e jara boemo bo bolokiloeng ba mosebetsi o mocha o lokelang ho etsoa. Liphetoho tsa maemo ke karolo ea bohlokoa ea ho etsa lintho tse ngata me li ka ama tsebetso le tsebetso ea sistimi, kaha li kenyelletsa nako ea ho sebetsa le ho sebetsa.
