When a page fault occurs, the process requesting the page must block while waiting for the page to be brought from disk into physical memory. Assume there exists a process with five user-level threads where the mapping of user threads to kernel threads is many:one. If one user thread incurs a page fault while accessing its stack, would the other user threads belonging to the same process also be affected by the page fault (i.e., would they also have to wait for the faulting page to be brought into memory?) Explain.
Consider a system that uses pure demand paging:
a. When a process first start execution, how would you characterize the page fault rate?
b. Once the working set for a process is loaded into memory, how would you characterize the page fault rate?
c. Assume a process changes its locality and the size of the new working set is too large to be stored into available free memory. What are some options system designers could choose from to handle this situation?
All of the following are events except: a macro running in response to a form button being clicked, changing the data in a cell, clicking on a control button or opening or closing an Excel workbook.
Explain why in some image processing scenarios, filters are used instead of point operations on pixel values Show with diagrams how the Median Filters work
Give an asymptotic formula for each of the recurrence equations given below, using big "Θ" rather than just big "O" for better results when possible.
For each of these sublists, the median is found. Further, the median of these medians is found and returned as the pivot. Perform the analysis and prove the new bounds.
