The correct answer is: A. multitasking
Multitasking is the ability of an operating system to run multiple programs at the same time. This is done by switching between the programs very quickly, so that each program appears to be running continuously.
Multitasking can be done in two ways:
- Preemptive multitasking: The operating system takes control of the CPU and decides which program to run next. This is the most common type of multitasking.
- Cooperative multitasking: Each program is responsible for giving up control of the CPU when it is finished with its current task. This is less common than preemptive multitasking, but it can be more efficient.
Multitasking can be beneficial for users because it allows them to do multiple things at once, such as checking email while working on a document. However, it can also lead to problems if programs are not designed to be multitasked. For example, if two programs are trying to access the same file at the same time, it can cause data corruption.
B. multi-processing is the ability of an operating system to run multiple programs on multiple processors. This is different from multitasking, which can be done on a single processor.
C. multi-operating is not a term that is commonly used in the context of operating systems. It may refer to the ability of an operating system to run multiple operating systems on the same computer.
D. multi-paging is a technique used by operating systems to manage memory. It involves dividing memory into pages, which can then be swapped in and out of memory as needed.
E. None of these is the correct answer.
