- (a)What is the biggest size we can have for a file with SFS? (b)Provide data block numbers in sequence that will be read from the disk (only data blocks that contain file data) when read_t (inum, offset, buf1, count) is called in a user program, where inum is the corresponding inode number for the above inode, and buf1 is a pointer that points to a user-defined buffer.arrow_forwardQuestion no 07: Write C Program Code to simulate Worst-Fit memory management Algorithm for the following Process.

The character in column 1 should be either A or B and in the column 2 should be a digit. If both columns contain appropriate values then update is made. If the input of column 1 is incorrect, i.e. neither A nor B, then message X will be displayed. If the input in column 2 is incorrect, i.e. input is not a digit, then message Y will be displayed. A file must be updated, if the character in the first column is either "A" or "B" and in the second column it should be a digit. If the value in the first column is incorrect (the character is neither A nor B) then massage X will be displayed. If the value in the second column is incorrect (the character is not a digit) then massage Y will be displayed. Draw a Cause-Effect graph for the above situation and generate test cases through the corresponding decision table.arrow_forwardIn 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.

- Assume that main memory is composed of only three page frames for public use and that a seven-page program (with pages a, b, c, d, e, f, g) requests pages in the following order:a, c, a, b, a, d, a, c, b, d, e, f 2. Increase the size of memory so it contains four page frames for public use. Using the same page requests as above and FIFO, do another page trace analysis and compute the failure and success ratios. 3. Calculate the cache hit ratio using the formula presented in this chapter assuming that the total number of requests is 2,056 and 647 of those requests are found in the cache.arrow_forwarda.

- 2. Write a program that opens a file in read-only mode and maps the entire file into the virtual-memory address space using mmap. The program should search through the bytes in the mapped region, testing whether any of them is equal to the character X. As soon as an X is found, the program should print a success message and exit. If the entire file is searched without finding an X, the program should report failure. Time your program on files of varying size, some of which have an X at the beginning, while others have an X only at the end or not at all. Please write the program in Carrow_forwardComputer Science Task: Given two matrices X and Y, multiply them in parallel to store the result in matrix Z You should write an openMP program with the following points in consideration: Analyze the speedup and efficiency of the parallelized code. Vary the size of your matrices from 100,1000, and 2000 and measure the runtime with one thread. For each matrix size, change the number of threads from 2,4,8., and plot the speedup versus the number of threads. Compute the efficiency. Explain whether or not the scaling behavior is as expected.arrow_forwardAssume that the following are concurrent VHDL statements: (a) L <= P nand Q after 10 ns; (b) M <= L nor N after 5 ns; (c) R <= not M; Initially at time t = 0 ns, P = 1, Q = 1, and N = 0. If Q becomes 0 at time t = 4 ns, (1) At what time will statement (a) execute? (2) At what time will L be updated? (3) At what time will statement (c) execute?
