1. Alberta Einstein teaches a business class at Podunk University. To evaluate the students in this class, she has given three tests. It is now the end of the semester and Alberta asks you to create a program that inputs each student’s test scores and outputs the average score for each student and the overall class average. (Hint: The outer loop should allow for Ms. Einstein to input all the students, one by one, and the inner loop should accept the three test scores and compute the average for each student.)

ICMP time expired error messages have two meaning? 1.) TTL expired is one reason 2.) what is the other time expired reason? explain fully with an example if possible.

C Programming: Write a program that will guess an integer that the user has picked. Imagine that the user will write down a positive integer x on a piece of paper and your program will repeatedly ask questions in order to guess what x is, and the user replies honestly. Your program will start by asking for an int n, and you must have 1 ≤ x ≤ n. After that, the program will successively guess what x is, and the user must tell the computer if x is equal to the guess (entering ’e’), larger than the guess (entering ’l’), or smaller than the guess (entering ’s’). Your program will guess by maintaining a lower bound (initially 1) and upper bound (initially n) and pick the largest integer equal to or smaller than1 the midpoint of the lower bound and upper bound. If the user responds with ’l’ indicating that x is larger, the guess becomes the new lower bound plus one. If the user responds with ’s’ indicating that x is smaller, the guess becomes the new upper bound minus one. If the user responds with ’e’ indicating that x is the guess, your program will report the number of guesses made and terminate execution:

Example 1)

Enter n: 50

Is your number 25? l

Is your number 38? l

Is your number 44? s

Is your number 41? e

Your number must be 41. I used 4 guesses.

Example 2) Enter n: 9

Is your number 5? s

Is your number 2? l

Is your number 3? s

Error: that’s not possible.

Example 3)

Enter n: -2

Error: n must be positive.

Example 4)

Enter n: 9

Is your number 5? m

Error: invalid input.

Example 5) Enter n: a

Error: invalid input.

In python, how do I define a function (check_domain) which takes a email (string) and domain name (string) as input. using slice, it will return true if the email address' domain same matches the input domain name. For example, when input are ”[email protected]” and ”msn.com”, the function you defined should return True. When input are ”[email protected]” and ”hotmail.com”, it should return False

Write method that takes a 2D square array and two integer values that represent the indices of the two columns. Method swaps the first two columns.

int[][] in = {{1,2,3}, {3,2,4}, {4,2,7}};

would output 213234247

public static void swap(int[][] in, int index1, int index2) {

(For C++) Assume that sentence is a variable of type  string  that has been assigned a value . Assume furthermore that this value is a string consisting of words separated by single space characters with a period at the end. For example: "This is a possible value of sentence."

Assume that there is another variable  declared , secondWord, also of type  string . Write the statements needed so that the second word of the value of sentence is assigned to secondWord. So, if the value of sentence were "Broccoli is delicious." your code would assign the value "is" to secondWord.

List the relational operators recognized by Python, and explain their meanings

Explain Business Intelligence in one page or less. Focus upon the concept that ‘BI’ is an umbrella term and explain what the components of a ‘BI’ system are and what its architecture and purpose are.

Given the following list of values, perform a binary search for the indicated search item. Use the binary search algorithm on pg. 1026 of our textbook. Show the values of first, last and middle, and the number of comparisons made after each iteration of the loop. Your should create a table like the following to show your work, where first and last are the values of the variables at the beginning of the loop, and mid is the midpoint used during that iteration, list[mid] is the value in the list at the midpoint, and No. of key comparisons should be the number of comparisons made during this iteration by the algorithm:

Iteration  first   last    mid  list[mid]   No. of key comparisons
1          0       12      ?    ?           ?

List:
[ 2, 3, 4, 4, 5, 7, 10, 14, 15, 17, 22, 23, 24 ]

Searching for value: 3

Language: Python

Create a graph and then set initial and goal states such that the number of nodes visited for BFS is smaller than that in DFS. Now modify the initial and goal state such that the number of nodes visited for BFS is larger than that in DFS.

Write a program, which will act as a simple four-function calculator. That is, it will read a number, read an operator, read another number, then do the operation. The calculator works with integers and uses four functions: +, -, *, and /. After the first operation is completed, the program will read another operator and uses the result of the previous operation as the first value for the next operation. If the user enters either an upper- or lower-case C the result is cleared and then the user starts entering a new number. If the user enters an X, the calculator is turned off. The various input values (i.e. numbers, operators, commands) will be followed by the ENTER key. Your program should prompt the user on what the user is to do. The commands C and X may be entered in place of an operator.

NOTES:

The person using the calculator has a terrible time using a keyboard and may not always enter a valid operator. If this happens the program should ask for another operator. Regardless of the math operation attempted, the program must not die. If the math operation would cause a fatal error in your program you should check for it and issue an error message rather than attempting the operation.

Please write the code for C programming, not C++ or Java

USE PYTHON ONLY

Please write a Python program to let you or the user play the game of rolling a dice and winning/losing money. Initially, you have 100 dollars in your account. You place a bet to roll the dice. The game will be stopped if your bet is zero. First, dealer would roll the dice and get a number from random.randint(1, 6). Then, you would roll the dice and get a number from random.randint(1, 6). Now, compare your number with dealer’s number to see whether you won or lose the bet. If you lose, the bet would be deducted from your account. If you won, the bet would be added to your account. If it’s a tie, your account is not touched. Then, continue the game of putting your bet until your bet is zero. The game is to continue even when you have zero or negative amount of money. You must test your game program 3 times with at least 10 rounds for each game. The output of your test case #1 may like as follows: Welcome to the Rolling Dice Game of TM

Network Analysis and Theory

a) In your opinion what are the biggest threats to a network in terms of security and why?

b) Describe what you would do to protect a network from attack, mention any appliances or products you can recommend.

Risk analysis is one way to monitor security in an organization. Risk analysis can be a time- consuming process; it involves a number
of steps, some of which require “educated guessing.” Nevertheless, the process alone raises awareness of security issues even if no immediate actions are taken as a result. The steps are:

i. Identify assets (infrastructure, people, hardware, software, reputation, etc.).

For the rest of this list, we’ll concentrate on a single asset.

ii. Determine vulnerability (what event or events might happen to the asset. For example, the building could catch fire, the website could be hacked, etc.).

For the rest of this list, we’ll concentrate on a single asset vulnerable to a single event.

ii. Estimate the probability per year of this event (based on past data, expert estimates, etc.). Take current security measures into account.

iv. Estimate the expected cost if this event occurs (cost to repair or replace, cost of lost business, etc.).

v. Compute risk exposure 5 cost estimate 3 probability estimate.

vi. Identify any additional security measure X that would help protect against this event, determine what it would cost, and do a calculation of the risk exposure with the additional security measure X in place.

vii. Do a cost-benefit analysis:
(Risk exposure without X – Risk exposure with X) − Cost of X

You have a small web-based business that uses a single server to manage your webpage and your customer information. Over the past four years, your website has been hacked and taken down twice. You estimate that the cost of this event is $600 to clean the server and reload the webpage and $12,000 in lost business while the server is down.

1. You could purchase a backup server for a cost of $3,000, which you estimate would reduce the probability per year of losing your website to 0.2. Would this be a cost- effective security measure?

2. What if you reevaluate the probability per year with the backup server to be 0.3. Does this change your answer?
