*Last week, my class took a quiz on Unit 1. I missed three of the twenty questions and was able to navigate my way to the correct answer on seventeen of the questions. The first problem I missed was:*

I selected 31 as the answer to the problem, when the answer should have been 16. In the equation x+= 5 * I, x has a starting value of 1. When i is 1, the equation becomes 1 + (5*1) which is equal to 6. When i is 2, the equation becomes 6 + (5*2) which is equal to 16. The i value must remain less than 3, which is the mistake that I made in solving the problem. I added 16 + (5*3) to get 31, but I now understand that 3 should not be included in the values for i due to the "<" sign.

The second question I missed was: "When communicating within a network, a few things are important. Of the list below, which is most important? " The options were numbers, message, timing, and distance. I selected distance because I figured that one's distance from a network would have the most impact on the network's strength and availability. However, the correct answer was timing because the time a network takes to process information is vital to the efficiency of the network.

The third question I missed was: "When the number of bits is not large enough to hold the number - what happens?" I selected "a program will stop running and produce an error message" because in many of the codes I have written, an error message has been produced at some points. However, the correct answer is, "the higher order bits will be lost." The higher order bits are lost to preserve the accuracy of a number after the decimal point.

One question that was tricky that I answered correctly was: "Which of the following only requires a single bit of storage to represent the data?" The options were a score on a math test, any number modulo 2, Hertz, and the temperature outside. This question required a bit of thinking as almost all of these answers require a low amount of bits of storage. However, one bit of storage corresponds to only one character. Any number modulo 2 will result in either 0 or a single digit ranging from 1-9 that is the remainder. Therefore, only one character will be used, making this the correct answer.

A second question that was tricky that I answered correctly was:

For this problem, you had to follow the order of operations to get the right answer. "b" times "c" must be performed first and then "a" must be added to that total. "b" times "c" is equal to 15 and 15 + 10 is 25, making 25 the correct answer. Other students may have gotten this question wrong due to incorrectly following the order of operations.
