Answer: Short-term Scheduler
Notes: The short-term scheduler is also known as the CPU scheduler. Its main objective is to increase system performance in accordance with the chosen set of criteria. It decides which of the ready, in-memory processes is to be executed after a clock interrupt, an I/O interrupt, an operating system call or another form of signal. Thus, the short-term scheduler makes scheduling decisions much more frequently than the long-term or mid-term schedulers.
