What is the main difference between a mainframe and a super computer?
Answer: C
Correct answer: Supercomputers are focused to execute few programs as fast as possible while mainframe uses its power to execute as many programs concurrently
The difference is in what each optimises. A supercomputer is built for raw speed on a small number of very heavy computations - weather models, simulations - and is measured in floating-point operations per second. A mainframe is built for throughput: thousands of concurrent transactions, with reliability and input-output capacity mattering more than arithmetic speed. Physical size has nothing to do with it.
