The Liu-Layland scheme for testing schedulability uses the equations U= Σ and T₁ U≤n 2¹-1 where Cis the execution time, Tis the task time period, n is the number of tasks to be scheduled and U is the CPU utilization. - (d) For a real-time operating system that has 4 tasks with execution time of (1, 4, 2, 4) with corresponding task time periods of (4, 10, 6, 10), comment on the schedulability.
