2/6
Correct. A modify bit is an MMU bit used to indicate that a frame has
been modified (and therefore must have its contents saved before
page replacement).
1 / 1 pts
Question 2

is a____________.
frame-allocation algorithm
ROM
replacement
byte
Correct. A frame-allocation algorithmis the operating-system
algorithm for allocating frames among all demands for frames.

Last weekend, Mr. Moki took Daniel to a family reunion. Since Daniel had never attended a reunion, Mr.
Moki introduced him to the four other kids in the room. Five kids then sat together. When Mr. Brown
asked about their age, the first kid A said, "I am 2 years older than B on my left." B decided to do the
same and said, "I am 2 years older than C on my left as well." C imitated, "I am 2 years older than D on
my
left." D said, "I am 2 years older than Daniel." When it came to Daniel, he answered honestly that he
was 10.
Mr. Moki burst into laughter and asked, "This is fun. How will you solve this problem?"
"I am 10, so D is 10+2=12, C is 12+2=14, B is 14+2=16, and A is 16+2=18." Daniel answered quickly. "Well
done!" said Mr. Moki, "Can any of you generalize a formula?" B reckoned that this was a recursive
relation. A, who had been learning to program, said that this could be easily implemented by a loop

The college ground is rectangular in shape. The Management decides to build a fence around the ground. In order to help the construction workers to build a straight fence, they planned to place a thick rope around the ground. They wanted to buy only the exact length of the rope that is needed. They also wanted to cover the entire ground with a thick carpet during rainy season. They wanted to buy only the exact quantity of carpet that is needed. They requested your help.
Help them by writing a C program to find the exact length of the rope and the exact quantity of carper that is required?
Input Format:
Input consists of 2 integers. The first integer corresponds to the length of the ground and the second integer corresponds to the breadth of the ground.
Output Format:
Refer Sample Input and Output for exact formatting specifications.

Now, consider at least one interface that you use at least several times a week. Think outside of the box - this doesn't have to be your computer - in fact, I would prefer it NOT be - it can be your phone, your television, or some other electronic interface. Describe concisely (no fluff, please!) how at least TWO of the "Laws of Grouping" were applied to the design of the interface that you chose.

Rewrite the following paragraph with the proper punctuation marks where you see fit: Clarence the valedictorian for this school year decided he did not want to go to college and people were shocked. Everybody thought he would go to a prestigious university like Harvard or Princeton but he decided he wanted to join the Marine Corps. When he was asked why he did not want to go to college he said that he didn’t like school he always wanted to wear the uniform and he wants to be Marine Reconnaissance the special force unit of the Marine Corps. Upon this revelation no one doubted that Clarence could not be special force one day, he had this drive when he sets his mind on something he would give it his all and accomplish it.

There will be a flight out at8:00pm every evening. Each person can see everyone else's eye color, but they do not know theirown (nor is anyone allowed to tell them). Additionally, they do not know how many people haveblue eyes, although they do know that at least one person does. How many days will it take theblue-eyed people to leave?

Computer Science
Using computers and other automated tools to grade true-false and multiple-choice tests is widespread, but grading essays has been reserved for instructors. Until now. Software developed by a nonprofit enterprise founded by Harvard and MIT recently released software that can grade student essays and short written answers. Students answer online instead of in a blue book and immediately receive their grade after clicking a Send button. The software uses artificial intelligence (it initially “learns” how to grade an instructor’s test by reviewing 100 essay exams that the instructor scored) and is designed to free up professors for other tasks, as well as give students the opportunity to immediately revise their graded essays for an improved grade. But does the system work? Are the automated grades similar to what a human grader would award? Skeptics (including the National Council of Teachers of English) say no. Objections include a lack of tests to support the validity…

• Roll the dice
• Allow player to select which number(s) to "shut"
and determine if that move is valid.
o Use GUI for selecting which tiles (numbers)
to shut
o Graphically display status of tiles - open or
shut
• Continue until the player "shuts the box" (closes
all numbers) or can't play (no valid moves left).
• Display the players score at the end - "You Win"
or total of remaining numbers.
