• Explain the challenges the forensic investigator has when conducting an investigation on a network. What are the things they would need to do if they are not part of the organization versus being part of the organization?

1. SNAP stands for______________ .

2. The ability of FDDI and other high-availability fiber networks to wrap connections on either side of a break is due to the dual _______________ rings.

3. Which of the following is a cell-based protocol?

4. Given a small local area network of 10 systems, what is the best device, where best is best performance without additional unneeded functionality, to connect all 10 systems to each other. Assume that all of the systems need to transfer large files frequently between each other, but that there is no need for external access/communication outside of the LAN.

5. Given an analog signal with the highest frequencies at slightly below 5KHz, what would be the best sampling frequency, where best means the lowest sampling frequency that will still accurately allow the original signal to be regenerated.

6. The three key public network components are____________________, 

Section 2 Please answer all question in detail and in your own words.

What is a collision on an Ethernet network? What happens in the case of a collision?

Describe 5 network topologies (briefly) and give an advantage and a disadvantage for each.

Describe what a VLAN is. How is this useful for a geographically dispersed company? What advantage to the end user does this provide?

For this week’s project, you are to first conduct an Internet search on “How to Secure Home Wifi.” With those results, you are to create your own tutorial that you could give to your family or friends on how to configure your home wifi to be secure. Your tutorial should include step-by-step instructions on how to do it. Include technical settings for a home router as necessary. Images and graphics showing steps are encouraged. 
Any information or picture taken from a reference must be cited. Also, you must be able to explain your instructions, so no copying from your Internet reference. 

———-

Your tutorial should be at least two pages in length.

Chapter 4 Running Case Portfolio

Need help with my section of the paper. I attached the case study and copy of the paper. Please answer A and B with reference please. I need within 12 hours.

A. Different IT Solution:

• Describe the solution 
• Describe the major benefits and the extent to which it solves the problems identified in Section II 
• Identify the major cost elements and provide an estimated cost for the solution 
• Discuss the general feasibility of the solution – whether or not it is feasible and the reasoning behind the statements 
• Identify the top three risks (organizational, financial, IT, etc.) 
• Describe the major defining issues – things that would make it a less desirable solution than the proposed solution, or, in the case of the proposed solution, why it is the best alternative in general. 

B. Process Change 

• Describe the solution 
• Describe the major benefits and the extent to which it solves the problems identified in Section II 
• Identify the major cost elements and provide an estimated cost for the solution 
• Discuss the general feasibility of the solution – whether or not it is feasible and the reasoning behind the statements 
• Identify the top three risks (organizational, financial, IT, etc.) 
• Describe the major defining issues – things that would make it a less desirable solution than the proposed solution, or, in the case of the proposed solution, why it is the best alternative in general. 

1. Conduct a critical analysis of two of your classmates’ proposed topics by the last day of the workshop.
2. Each response to your classmates should be at least 150 words in length and should include APA citation to one credible information source.

Please find the attached document. 

 The third assignment involves writing a Python program to compute the cost of carpeting a room. Your program should prompt the user for the width and length in feet of the room and the quality of carpet to be used. A choice between three grades of carpeting should be given. You should decide on the price per square foot of the three grades on carpet. Your program must include a function that accepts the length, width, and carpet quality as parameters and returns the cost of carpeting that room. After calling that function, your program should then output the carpeting cost.

Your program should include the pseudocode used for your design in the comments. Document the values you chose for the prices per square foot of the three grades of carpet in your comments as well.

You are to submit your Python program as a text file (.py) file. In addition, you are also to submit a test plan in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report. 

check for the question in the file below

You will need to research the purchase of 50 new PCs, with the requirement to replace all existing desktops with laptops. Your recommendation must account for multiple external monitors, additional peripherals via USB 3.0, physical security mechanisms, and the capability to allow the end user to quickly disconnect from the office environment. 

You will complete the project in two sections:

In Section 1, you will conduct research based on the Corporate PC Refresh Documentation. You should carefully document any assumptions made (e.g., how you analyzed the requirement for upgrading monitors, peripherals devices, etc.). 

In Section 2, you will use a configurator to detail the specifications you will provide your recommended device model(s) 

Follow the instructions in the Desktop Migration Proposal Template to get started.

 the assignment is about using multithreading for parallel programming. In the assignment folder you will find:

• zip file for examples of using Java Multithreading main functions.
• the pdf version of the assignment
