2. Before multitasking operating systems came about, how were multiple tasks run on a computer?

3 (25 pts) Weve come up with a new process scheduler for an interactive multitasking operating system. Intended for desktop computers running at about 5 million instructions per second (5 MIPS), the scheduler is based on a single-queue preemptive round-robin scheme with a quantum of 1 microsecond (1/1,000,000 of a second). Discuss the performance of this scheduler, especially with respect to eciency and response time
