Multiprogramming

Determine whether the following statements are true or false.

Group of answer choices

Multiprogramming means that multiple processes can be loaded in memory at the same time, and share the processor concurrently.

Memory management strategies would not be necessary if the main memory was very fast, very large, and persistent.

"Swapping" is a method to achieve $*$true$*$ multiprogramming.

If a hard$-$drive has a bandwidth of $100$MB$/$s$,$ then it takes $1$ second to switch between two $100$MB processes when using swapping.

Multiprogramming is meant to maximize the usage of the CPU and of the memory.
