Which mechanism is used to switch between processes in multitasking operating systems?
- Context switch
- Inter-process communication
- Interrupt handling
- Resource allocation
In multitasking operating systems, the mechanism used to switch between processes is known as a context switch. A context switch involves saving the state of a currently running process, including its registers, program counter, and other relevant information, and then loading the state of the next process to be executed. This allows the operating system to efficiently allocate CPU time among multiple processes, enabling concurrent execution and multitasking capabilities. Understanding context switching is crucial for system performance optimization and multitasking efficiency.
