See lessAdvantage(s) of using assembly language rather than machine language is (are):
One key benefit of using assembly language is that it allows programmers to write highly optimized code for the specific hardware a program will run on. This is because assembly language instructions map directly to the machine language instructions that the CPU can execute.

See lessRound-robin scheduling
Round-robin scheduling (Figure 7.151) allocates each task an equal share of the CPU time. In its simplest form, tasks are in a circular queue and when a task's allocated CPU time expires, the task is put to the end of the queue and the new task is taken from the front of the queue.
