Potpourri_3 TS-Linux   3. [2 points] (True/False with justification) Consider a TS-Linux system where the throughput-oriented background tasks are guaranteed a 1/4th proportion of a CPU time period T. There is a time-sensitive task that is guaranteed a 1/3rd proportion of a CPU time period T. A user tries to add another time-sensitive task to the system that requests a ½ proportion of a CPU time period T. Since TS-L is designed to decrease the latency of time-sensitive tasks, the proportion scheduled to the background tasks is decreased to 1/6th of the CPU time period T.
