Consider a disk queue with requests for I/O to blocks on cylinders 47, 38, 121, 191, 87, 11, 92, 10. The C-LOOK scheduling algorithm is used. The head is initially at cylinder number 63, moving towards larger cylinder numbers on its servicing pass. The cylinders are numbered from 0 to 199. The total head movement (in number of cylinders) incurred while servicing these requests is
I need to design, analyze, and implement algorithms to read in a sequence of characters from standard input and maintain the characters in a linked list with no duplicates. When read in a previously unseen character, insert it at the front of the list. When read in a duplicate character, delete it from the list and reinsert it at the beginning. The program implements the well-known move-to-front strategy which is useful for caching, data compression, and many other applications where items that have been recently accessed are more likely to be re-accessed. The program should read a sequence of characters and should insert unseen character at the front of the list. The program should check if the character is not in the list to be inserted at the front of the list. The program should delete a duplicate character and delete it from the list and insert it at the beginning of the list. The program should check if the character is already in the list and delete the character from the list…
A common implementation of sequential files on disk has each block point to its successor, which may be any block on the disk. This method requires a constant amount of time to write a block (as the file is originally written), to read the first block in the file, and to read the ith block, once you have read the 1 - 1” block. Reading the lth block therefore requires time proportional to 1. Show how by adding just one additional pointer per node, you can keep all the other properties, but allow the lth block to be read in time proportional to log I. [Hint: heaps have implicit pointers from node I to what other nodes?] Explain what the algorithm for reading the th block has in common with an algorithm for raising a number to the ith power in time proportional to log 1.
Suppose that a disk drive has 40 cylinders, numbered 0 to 40. The drive is currently serving a requestat cylinder 20 (the previous request served was at cylinder 19) when the last of these requests is madewith none of these requests yet served. The queue of pending requests, in FIFO order, is 5, 25, 18, 3,39, 8, and 35. A seek takes 5ms per cylinder movement. Starting from the current head position, whatis the total distance (in cylinders) that the disk arm moves to satisfy all the pending request and alsocalculate the total seek time needed to serve these requests, for each of the following disk-schedulingalgorithms? Explain with the help of a diagram in each case. a. FCFSb. SSTFc. SCANd. LOOK

Make the difference between a cache that is directly mapped and one that is totally associative.
Write a c++ code that implements a program that compares the running time for two loops which access very different number of array elements but which should have roughly the same number of cache misses. Try to estimate the average time for an array access with a cache miss and one without. use the following two loops (in the screenshot provided)
Conflict Based on what we've learned about caches in this class, which of the following situations will cause two blocks to conflict? a) diff tag diff set, diff offset b) diff tag, diff set, same.offset c) diff tag same set, diff offset d) diff tag same set, same offset e) same tag diff set diff offset) f) same tag, diff set, same offset g) same tag, same set, diff offset h) same tag, same set, same offset please I need correct answers in 45 minutes I will give upvote
write two functions: insertNode and forwardTraverse, for an XOR linkedlist, a.k.a, memory efficient doubly linked list (DLL) in C PL. Ordinary DLLs requires space for two addresses(one pointing to previous node and one to next node). However, XOR LLs use bitwise XOR operation tosave space for one address. Consider the below ordinary DLL.
Consider the following code snippet in C: char *base_url = malloc(11 * sizeof(char)); printf("Enter an 11 character URL: "); scanf("%s", base_url); char src[11]; char dst[11]; // copies base_url to src strncpy(src, base_url, 11); // copies src to dest strcpy(dst, src); printf("src: %s dst: %s\n", src, dst); Identify at least one potential buffer overflow vulnerability and explain why/how it can be exploited (i.e., not just that it’s a buffer overflow, but where the problem will manifest itself).
Draw a line between a cache that is fully associative and one that is directly mapped out.
To solve the problem of mismatch between the speeds of computer and printer, we usually use a buffer. Computer writes data to the buffer, and then printers get data from buffer. Which data structure could be used to implement the buffer? (A) Stack (B) Queue
