Brief Introduction

Suppose that you are an analyst for the ABC Company, a large consulting firm with offices around the world. The company wants to build a new knowledge management system that can identify and track the expertise of individual consultants anywhere in the world on the basis of their education and the various consulting projects on which they have worked. Assume that this is a new idea that has never before been attempted in ABC or elsewhere. ABC has an international network, but the offices in each country may use somewhat different hardware and software. ABC management wants the system up and running within a year.

Action Items

• Given the situation, what methodology would you recommend that ABC Company use? Why?
• Support or Oppose the above statements with arguments
• Respond to two other class member postings: observe and criticize their statements

Please explain answer and show steps

If your current Network ID is 223.40.35.0 with the default subnet mask and you need to have 15 subnets and maximizing the number of valid node IP addresses what would be the most appropriate subnet mask?

1. 255.255.224.0
2. 255.255.255.224
3. 255.255.240.0
4. 255.255.255.240

Given the following IP address from the Class B address range using the default subnet mask: 100.110.0.0. Your network plan requires no more than 64 hosts on a subnet. When you configure the IP address in Cisco IOS software, which value should you use as the subnet mask?

1. 255.255.0.0
2. 255.255.128.0
3. 255.255.255.128
4. 255.255.255.252

Given an IP address of 131.107.2.104 and a subnet mask of 255.255.255.224, which of the following is the other form of representing this address?

1. 131.107.2.104/26
2. 131.107.2.104/24
3. 131.107.2.104/25
4. 131.107.2.104/27
5. 131.107.2.104/19

Identify how many valid host addresses can you have on 192.168.27.32 network with a subnet mask of 255.255.255.240.  

1. (2^4) - 2
2. (2^3) – 2
3. (2^2) - 2
4. (2^1) – 2

Please debug this by fixing all the mistakes so it will compile in C#

// Program prompts user for any number of values
// (up to 20)

    public static void Main()
    {
        const int QUIT = 999;
        int[] numbers = new int[20];

        double average;
        double total;
        string inString; // intString
        Console.Write("Please enter a number or " +
           QUIT + " to quit...");
        inString = Console.ReadLine();
        num = Convert.ToInt32(inString); // inString
        x = 0;
        while ((x < numbers.Length))
        {
            numbers[x] = num;
            ++x;
            total = +numbers[x]; // =+ not +=

1) What are the values of doing formal evaluation?

2) What do you see as the drawbacks of evaluation?

Mark Arnez of Aspen consulting has been contacted by a client who represents an international company with locations in your city, in Toronto, and in London. Each location has a plant for making parts for boilers used in large buildings. There also are sales and parts distribution offices at the plants. All buildings currently are networked using 10-Mbps communications to each workstation or server and 100-Mbps communications between floors. The client is exploring ways to link the business networks at all three locations. Form a team to determine the best way to connect the locations. Use the internet to research some gross estimates of the costs.

3-1. On your first visit with gray sharma, he tells you he would like to know about some basic network designs. use microsoft paint or another drawing package to draw examples of the basic network topologies for gray. then, use the space below to summarize those topologies.

Explain the advantages and disadvantages of the topologies you summarized for gray in Assignment 3-1. Based on what you know at this point, which topology would you recommend for the physicians building? why would you recommend it?

(C++) Write a program that prompts the user for the length of one side of a triangle and the sizes of the two adjacent angles in degrees and then displays the length of the two other sides and the size of the third angle.

Assignment

Bigfoot has reportedly been seen in Southeast Texas forests. We have a drone searching for Bigfoot that can take pictures from the air. During a 24-hour period the drone can fly over the forest 3 times. On each flight we estimate Bigfoot will be in range of the camera on the drone for 2 minutes. The camera can take 10 photos per minute. We estimate there is a 30% chance Bigfoot will appear on each photo taken.

Run a simulation of our drone taking photos of Bigfoot. For each picture taken, generate a random number from 0-100 and compare it to the percentage chance Bigfoot will appear in the photo. Calculate the number of photos taken during the 24-hour period and print it. Calculate the number of photos taken during 24-hour period in which Bigfoot appears in the photo and print that also.

Run the above simulation 5 times. At the end, compute the average number of photos taken (rounded down) during a 24-hour period in which Bigfoot appears (by averaging the number of photos taken of Bigfoot during all of the 5 simulations).

Run your program. Your program must run successfully to receive full credit for this homework. Take a screenshot of your program. The screenshot should show all of your source code and the output of your program in the Console window. Resize the editor and/or console windows as needed so that everything is shown. You may also need to expand Eclipse to full screen size. If you program is too large you can take multiple screenshots so the source code is all shown and zip all the files together (use .zip format only, not .7zip, .rar or any other format besides .zip).

An example of output from the program might look something like:

Simulation 1: Photos of Bigfoot: 33 of 60

Simulation 2: Photos of Bigfoot: 37 of 60

Simulation 3: Photos of Bigfoot: 49 of 60

Simulation 4: Photos of Bigfoot: 40 of 60

Simulation 5: Photos of Bigfoot: 51 of 60

Average photos taken of Bigfoot: 42 of 60

Explain the MIS impact on revenue, fixed costs, variable costs, initial investment, training, implementation, customer acquisition, customer retention, and customer satisfaction .

Write a program to simulate rolling a six-sided fair die. Allow the user to enter the

number of rolls.

Your program should use rand() to get the result of die rolling.

Compute the number of occurrences for each number roll.

Calculate the percentage for each number roll.

Out put the results in the following format.

Use a do while loop to allow the user to repeat the process.

Here is the sample run for your program:

Please enter the number of die rolls

25

Number Frequency Percentage

1 3 0.12

2 6 0.24

3 10 0.40

4 1 0.04

5 3 0.12

6 2 0.08

Do you want to continue rolling die another time? Press Y or N

I want to be able to do it with a switch statement but am unsure

Use C++ write a "Design and implement a class of infix calculators" ,simply write a function named "evaluateInfix()" that evaluates infix expressions. It should have one string parameter and should return an int result. It should call a separate function named "infixToPostfix()" to convert the infix expression into a postfix expression, and then it should do the work of evaluating the resulting postfix expression. Then write a main() function to thoroughly test the function.

Use the pseudocode algorithm that evaluates postfix expressions given at the end of section 6.3.1 and the pseudocode algorithm that converts an infix expression to postfix form given near the end of section 6.3.2. Use the STL stack class.

Here is the pseudocode for 6.3.1

for ( each character ch in the string) {

if (ch is an operand)

Push the value of the operand ch onto the stack

else // ch is an operator named

{

// Evaluate and push the result

operand2 = top of stack

Pop the stack

operand1 = top of stack

Pop the stack

result = operand1 op operand2

Push result onto the stack

}

}

Here is the pseudocode for 6.3.2

for ( each character ch in the infix expression) {

switch (ch) {

case operand: // Append operand to end of postfix expression—step 1

postfixExp = postfixExp • ch

break

case '(': // Save '(' on stack—step 2

aStack.push(ch)

break

case operator: // Process stack operators of greater precedence—step 3

while (!aStack.isEmpty() and aStack.peek() is not a '(' and precedence(ch) <= precedence(aStack.peek())) {

Append aStack.peek() to the end of postfixExp

aStack.pop()

}

aStack.push(ch) // Save the operator

break

case ')': // Pop stack until matching '(' —step 4

while (aStack.peek() is not a '(')

{ Append aStack.peek() to the end of postfixExp

aStack.pop()

}

aStack.pop() // Remove the open parenthesis

break }

}

// Append to postfixExp the operators remaining in the stack—step 5

while (!aStack.isEmpty())

{ Append aStack.peek() to the end of postfixExp

aStack.pop()

}
