Answer:
By definition, <u>multiprocessing</u> refers to the processing of multiple processes at the same time by multiple CPUs.
By definition, <u>multiprogramming</u> keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.
The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.
Answer:
The missing word is <em>backing store.</em>
Explanation:
A backing store is a device for secondary storage of data that typically has greater capacity than the primary store but is slower to access.
A process must be loaded into memory in order to execute.
If there is not enough memory available to keep all running processes in memory at the same time, then some processes who are not currently using the CPU may have their memory swapped out to a fast local disk called the backing store.
The backing store may be the Hard Disk Drive or a Universal Serial Bus Drive. The backing store can sometimes be referred to as <em>virtual memory.</em>
This memory that appears to exist as main storage although most of it is supported by data held in secondary storage, transfer between the two being made automatically as required.

Scalar Values are single numbers or values, which may include integers, floating-point decimals, or strings of characters.
A(n) array is a group of scalar or individual values that are stored in one entity.
A(n) user-defined type is a data type that is assigned a true or false value by a programmer.
A(n) abstract data type is a data type that can be assigned multiple values.
