What is the role of write back buffers in write-through and write-back cachesIV. What is the impact of prefetcher on the different kinds of cache missesV. Illustrate why and what kind of hazards are addressed/not-addressed by registerrenaming
When feasible, what are the upsides of prioritizing the I/O queue as the place where processes would be executed? If the I/O connection suddenly goes down, what do you expect to happen? How would this affect the fastest possible CPU burst rate? I'm not quite sure I get what you're getting at here.
There are two basic approaches to the design of OS kernel. One is called microkernel approach, and the other is called ___ approach. In xv6, how many stacks are allocated for each process currently residing in the system? The PCB of a process in xv6 contains a pointer to the PCB of its parent process. The variable name of this pointer is ___. In xv6, there is a user-level C program that is used to create the first user process. The file name of this program is _______. Each system call in xv6 is associated with a system call ID (an integer number). The ID for system call read() is ______.

When a process p requests a resource using the request resource function, its state is set to ______________ if the requested resource is unavailable. Ready Blocked Ready Suspended The PCB contains an out-of-date copy of the CPU state of process Q when Q is running. True False The main benefit of using virtual CPUs is that they increase processing speed. True False
When this option is available, the I/O queue should be prioritised above the process execution queue. In what ways may this be beneficial? Who knows what will take place if there is a disruption in the I/O. It is unclear at this time if this will have an effect on the maximum burst rate of the CPU. I'm not really clear on the point you're trying to make here.
When allocating process execution to the I/O queue, what are the advantages of doing so first? If the I/O is interrupted, what do you believe will happen? Will this have an impact on the CPU's burst rate? What do you mean by that?
Think about the distinction that exists between a cache that is completely associative and one that is directly mapped.
The I/O subsystem holds the I/O requests in the I/O queue: <90, 12, 35, 100, 28, 74, 56, 9, 3, 45, 48, 104, 3, 175, 69, 95, 34, 11, 49, 2, 78>, the initial position of the read/write head is at cylinder 50. 1. Use SSTF and SCAN for computing seek distance. 2. Explain the advantages and disadvantages of the various I/O scheduling techniques. Please show all your work so i can see how you did it. Thanks!
Please explain how prioritizing the I/O queue above the process execution queue might improve performance. If the I/O is interrupted, who knows what will happen. To what extent this will reduce the maximum burst rate of the CPU is unclear. I don't think I understand what you're getting at.
