What is it called when a computer uses more than one CPU in parallel to execute instructions?
A.
Multiprocessing
B.
Multitasking
C.
Multithreading
D.
Parallel running
Explanation:
A system with multiple processors is called a multiprocessing system. Multitasking is incorrect. Multitasking
involves sharing the processor among all ready processes.
Though it appears to the user that multiple processes are executing at the same time, only one process is
running at any point in time. Multithreading is incorrect. The developer can structure a program as a collection
of independent threads to achieve better concurrency. For example, one thread of a program might be
performing a calculation while another is waiting for additional input from the user. “Parallel running” is
incorrect. This is not a real term and is just a distraction.References CBK, pp. 315-316 AIO3, pp. 234 – 239
