IT 600 Southern New Hampshire University Operating Systems Discussion

PART 1: DISCUSSION

Shared memory pages are an example of a topic where a picture is worth a thousand words. Find at least one illustration in Google Images by entering the search key “shared memory pages” in the search box. Be sure to enter it in the search box with quotes so the entire phrase is interpreted by the search engine as a single string.

Using an illustration you find, make that picture the focus of your post. Create a Discussion Topic post that outlines the function of shared memory pages. Go into detail about the proper operation of shared memory pages as described by the course textbook. If you find an illustration that does not agree with the course textbook, be sure to use it and make any inconsistencies the focus of your post.

It is very important that you properly attribute the image by listing the original author(s) of the illustration you find. Go to Citing Your Sources Guide to find instructions and examples of using proper attribution.

After your initial post, respond constructively to two of your peers’ posts after comparing your initial post to their initial posts. Justify your suggestions for the addition or revision of any of the benefits and drawbacks of using shared pages.

Comment on the accuracy of their specification of the conditions under which the practice provides performance benefits, as well as the specific instances when efficiency is negatively impacted.

To complete this assignment, review the Discussion Rubric PDF document.

PART 2:

Create a journal assignment in preparation for the memory management assessment elements of your final project.

Identify a graphical or command line utility that displays the allocation of virtual memory on your workstation. For example, memory_pressure provides information about the state of memory pages on OS X. The command or utility you choose must be part of the standard operating system’s distribution. Do not use third-party utilities. You are encouraged to select an operating system different from the one you used in previous lab exercises.

Execute the command and report on your findings in a journal assignment that provides insight into how the command you selected displays physical and virtual memory.

For additional details, please refer to the Module Five Journal Guidelines and Rubric PDF document.

ALL RUBRICS AND MATERIALS WILL BE SENT TO YOU.
