Step by step
Solved in 2 steps
- Discuss the circumstance in which there is insufficient memory for new processes and what actions the operating system should take to solve this problem.Discuss the situation in which there is no space for new process in memory and what kind of action should take by operating system to overcome this situation?Give a short summary of each of the four memory allocation mechanisms used by operating systems. Which two of the four alternatives are most often employed in real-life situations?
- What are the consequences if the available main memory is not shared properly among the number of processes by the operating system?If you were writing code for a real-time operating system, how would you go about designing it? If you were to design a system, what type of limits would you put on it? Be aware of instances where reaction times may be impacted by unanticipated circumstances. Does it stand to reason that a memory access may be slowed down?How does the concept of virtual memory contribute to the efficient utilization of system resources in modern operating systems?
- Should the operating system proceed with a higher level of care when working with information that is stored in memory rather than registers? If so, this raises the question of whether or not it should approach the system differently than it does with other kinds of data. Is there any room for error in this assertion, or does it provide the facts in an accurate manner?Each address generated by the CPU is compared to the relocation and limit registers; b) they use a protection algorithm; c) they are in separate memory spaces; and d) they use separate logical addresses, all of which ensure that the operating system and other processes cannot be altered by a running process.How does Direct Memory Access (DMA) operate to make the system more concurrent? To what extent does this make the development of hardware more difficult?
- How does Direct Memory Access (DMA) operate to make the system more concurrent?To what extent does this make the development of hardware more difficult?How could direct memory access (DMA), also known as direct memory access, enhance the concurrent behaviour of the system? How exactly does this make things more difficult for the development of hardware?Almost many computer users assume that when a multitasking process is underway, the CPU is actually processing all of the tasks that have been allocated to it at the same time.With the use of a single memory management strategy and a few interruptions, demonstrate to the average user what happens when you're multitasking in real time.
