In the context of ARM processors, what is the difference between a link register and a frame pointer?
The frame pointer points to the current frame and is set up by the programmer. The ARM processor uses register r11 as a frame pointer (by convention). Register r14 is the link register and this is enforced by the hardware (i.e., it’s an automatic function that the programmer cannot change). When a branch with link instruction is executed, the return address is saved in the link register automatically. Consequently, the link register is used to store the return address and a return from subroutine is implemented by copying the link register to the program counter.

Answer the following statements true (T) or false (F)
1) The traditional UNIX scheduler employs multilevel feedback using round robin within each of the priority queues. 2) First-come-first-served (FCFS) is a simple scheduling policy that tends to favor I/O bound processes over processor bound processes. 3) In the Highest Response Ration Next (HRRN) scheduling policy, longer jobs are favored because they yield a larger ratio from the smaller denominator in the equation. 4) A disadvantage of simulation is that results for a given run only apply to that particular collection of processes under that particular set of assumptions. 5) In fair share scheduling each user is assigned a weighting of some sort that defines that user's share of system resources as a fraction of the total usage of those resources.
