Question
For a 100-cylinder disk, compute the total number of head movements for the request queue provided below, using FCFS scheduling and a 100-cylinder disk (0-99). It is expected that the read write head is present at cylinder number 50 at the start of the program.
Request queue for disk cylinders has the following numbers: 75, 25, 30, 68, 40, 89, 10.

- In MIPS assembly, how do I iteratively read a file that contains only 2 numbers on each line, and calculate the distance between the two numbers on each line. Ex: file contains 1 5 4 7 function returns $v0=2 $a2 contains the array address [4, 3, default, default, default] also the file won't be greater than 300 mb and is never emptyarrow_forwardProblem 0. Suppose a file contains 100 bytes of data. A program successfully opens it for both reading and writing (i.e., passing the mode O_READWR to open()), and gets back a file descriptor number fd. a. The program, which has a 40-byte buffer, issues a call to read() for 40 bytes. It processes that data, and then repeats the call. Both calls return the exact amount requested. Then it issues a third read, again requesting 40 bytes. What value will it return? (Assume no other program has the file open.) b. Next the program calls write (fd, buffer, 40), and the call returns 40. Then it issues another read() call for 40 bytes. What value does that call return? c. Suppose the programmer needs to read back the 40 bytes just written. First it must use 1seek() to reposition the file pointer. What parameters should it invoke 1seek () with so that the next read call will return the 40 bytes just written?arrow_forwardCan you fix the code of the completion time based on the last execution of each process in the gantt chart and the output of the completion time must be the same as the image below?Code: #include <iostream>#include <queue>#include <string>#include <vector> struct Process { int processId; int burstTime; int priority;}; void print_gantt_chart(const std::vector<std::pair<int, int>>& gantt_chart) { std::cout << "Gantt Chart:" << std::endl; std::cout << "----------------------------------------------------------------------------" << std::endl; std::cout << "| "; for (const auto& process : gantt_chart) { std::cout << "P" << process.first << " | "; } std::cout << std::endl; std::cout << "----------------------------------------------------------------------------" << std::endl; std::cout << "0 "; int currentTime = 0; for (const…arrow_forward
