rWhich of these are types of multitasking?OptionsProcess basedProcess and Thread basedThread basedNone of the mentioned

The types of multitasking include:

1. Process-based: This type of multitasking involves the concurrent execution of different programs or processes. Each process has its own memory space and does not share it with any other process.

2. Thread-based: This type of multitasking involves the concurrent execution of different parts of a single program, known as threads. All threads within a process share the same memory space, which allows them to communicate with each other more easily than if they were separate processes.

3. Process and Thread based: This is a combination of the two above. It involves the concurrent execution of different programs or processes, and within those processes, different parts of a single program (threads) can also be executed concurrently.

So, the answer is "Process based, Process and Thread based, Thread based".
