1.	Which of the following is an aperiodic task requesting the processor at unpredictable times?(a) job(b) aperiodic task(c) sporadic(d) periodic taskThis question was addressed to me in an interview.My question is from Classification of Scheduling Algorithms in chapter Embedded Operating System, Middleware and Scheduling of Embedded Systems
Answer» CORRECT option is (C) SPORADIC Easiest explanation: The aperiodic tasks request the PROCESSOR at unpredictable times if and only if there is a minimum separation between the times at which they request the processor which is CALLED sporadic.
