Textbook Question
Chapter 3, Problem 26CRP
Would greater throughput be achieved by a system running two processes in a multiprogramming environment if both processes were I/O-bound (refer to Problem 25) or if one were I/O-bound and the other were compute bound? Why?

- _____ is a CPU design technique in which instruction execution is divided into multiple stages and different instructions can execute in different stages simultaneously.arrow_forwardWhen it comes to multiprocessing, you have the option of using either a symmetric or an asymmetric approach. What are the advantages of using several processors in a single application, as well as the disadvantages of doing so, and how may they be avoided?arrow_forwardIt would be preferable if the structures weren't kept in shared memory but rather were kept in each process' local memory and accessible via interprocess communication. What are a few of this design's flaws?arrow_forward
- A process's execution may be preemptively assigned to an I/O queue and then transferred to the CPU when it's ready. There's no telling what may happen if the I/O is suddenly cut off. Is the CPU's burst going to be diminished? How exactly does this hold true?arrow_forwardBoth symmetric and asymmetric forms of multiprocessing exist. Why would you want to use many processors for a single task, and what are the drawbacks of doing so?arrow_forwardIn the context of pipelining, explain the differences between dynamic and static scheduling of instructions. What are the pros and cons of each approach?arrow_forward
- When it comes to process execution, what is the advantage of first allocating it to the I/O queue and then pushing it to the CPU when it is ready? What, in your opinion, will happen if the I/O is not completed correctly? Is the CPU burst going to be affected? What do you mean?arrow_forwardRather of keeping shared structures in shared memory, an alternate design would be to store them in the local memory of a particular process and access them via interprocess communication. What are the disadvantages of such an architecture?arrow_forwardAn alternative to preserving shared structures in shared memory is to store them in the local memory of a single process and access them through interprocess communication. What are the drawbacks of this kind of architecture?arrow_forward
- What are the benefits of assigning process execution to the I/O queue first when it is possible to do so? What do you think will take place in the event that the I/O is interrupted? Will this have an effect on the maximum burst rate that the CPU is capable of? I'm not sure I understand what you mean by that.arrow_forwardThere are a number of benefits that come from the practise of first delegating the execution of a process to an input/output queue and then, once the CPU is ready, handing control back to it. Who knows what may occur if the input/output is suddenly stopped? Will there be an impact on the burst of the central processing unit? How exactly does this hold true?arrow_forwardAssigning process execution in advance to an I/O queue and then transferring control to the CPU when it is ready has several advantages. Who knows what may happen if the I/O is interrupted? Is the burst of the CPU going to be affected? In what way is this so?arrow_forward
