CSCI235 Study Guide - Final Guide: Second Normal Form, Bson, Functional Dependency

After successfully completing this assignment, students will be able to:

• Configure, run, and test a linux server in AWS' EC2
• Configure, run, and test a Windows server in AWS' EC2

1. Create an Ubuntu 20 LAMP server in EC2 like we did in class.
2. Verify your that Apache was installed by opening your browser and enter the public dns of your server in the address bar. If it does not connect either you did not add HTTP to the Security Group, or the install did not work properly. Take a screenshot and save it (for submission below).
3. The default location of html and php files is /var/www/html. Change to that directory. Now, using your favorite text editor use sudo to run your editor and create a file in that directory named info.php. For example, sudo nano info.php Then enter the following in that file to show information about the PHP installation: <?php phpinfo(); ?> Save the changes to the file and exit the editor.
4. Now in your browser, enter the public dns of your server in the address bar / info.php. For example, my public dns was ec2-54-89-230-235.compute-1.amazonaws.com, so I enter  as the url. Take a screenshot and save it (for submission below).
5. Create a Windows 2016 Server, like we did in class.  
6. Login to it using Remote Desktop.  Take a screenshot of Remote Desktop connected to your Windows Server and save it (for submission below).

Now that you have completed the assignment, stop or terminate your EC2 instances. Stopping them means that it is now longer running, but your data is saved. That means you will not accrue charges on your running server. Terminating will both stop and delete the instances (also not accruing charges).

• Screenshot of Apache page on your server shown in your browser
• Screenshot of the PHP info page on your server shown in your browser
• Screenshot of Remote Desktop session to your Windows Server

21. Suppose a process, P1, is running and the operating system uses the Paged Memory Management technique. Assume P1 has the following page-map table (PMT), and that the page size and the frame size are the same, each being 1024 bytes long. Assuming all addresses start from 0, the logical address 2564 is mapped to the physical address _, where (Frame X, offset Y) means byte number Y in Frame number X. Page Frame | 22 56 98 | 12 60 a) Frame 2, offset 516 b) Frame 98, offset 516 x c) Frame 2, offset 500 d) Frame 98, offset 0 e) None of the above

33. (2 points) Write a static sketch (no draw() or setup() that creates this image. Hint, use rectMode(CENTER), translate, rotoate, and the fact that if w is the width of one square, then the next one nested within it has width sqrt((w/2)*(w/2)*2). You should be able to see how that is derived by remembering the Pythagorean equation and looking at one of the triangles. The sketch is 500x500. One more hint, 45 degrees is the same as PI/4 radians. Although you may have trouble seeing them due to shrinking the image to fit on the page, there are a total of 20 squares in this image.
