Individual Homework: Text CompressionIn class we discussed measures of compression and a kind of text compression known as LempelZiv. Practice with these concepts in this homework.Compression measures1. I have a particular image I want to save. In TIFF format (uncompressed) it is 39,526 bytes.In PNG format, it is 8,494 bytes.a. What is the compression ratio? (uncompressed size/compressed size, expressed asa ratio)b. What is the space savings? (1 – compressed/original)2. I have a sound effect I want to use in a video game. I downloaded it in WAV format(uncompressed). The file size is 1.2 MB. I used iTunes to create an MP3 (compressed)version. The file size of the compressed version is 46 KB.a. What is the compression ratio? (uncompressed size/compressed size, expressed asa ratio)b. What is the space savings? (1 – compressed/original)Text compressionNow consider the following text (69 bytes):HOW MUCH WOOD WOULD A WOODCHUCK CHUCK IF A WOODCHUCKCOULD CHUCK WOOD3. Compress this as well as you can using Lempel-Ziv encoding. You can use the textcompression widget on Code.org. Write down each of the following:a. Dictionary (symbols and substitutions)b. Dictionary size (in bytes)c. Encoded textd. Encoded text size (in bytes)e. Total compressed size (dictionary + encoded text)f. Space savings (1 – compressed/original)

Chapter 9 explained reasons why universities should implement ERM. Do you agree with their reasons for ERM implementation in university settings. Should colleges implement ERM to help mitigate risks among students as well as employees? What is the biggest challenge you see with implementing ERM in the university setting?

To complete this assignment, you must do the following:

A) As indicated above, reflect on the ERM implementation in university settings, explain if they should be implemented and greatest challenges with implementation.

B) Select AT LEAST 3 other students’ threads and post substantive comments on those threads, evaluating the pros and cons of that student’s recommendations. Your comments should extend the conversation started with the thread. Replies should be completed by Sunday.

ALL original posts (4 in total) and comments must be substantive. (I’m looking for about a paragraph – not just “I agree.”)

NOTE: These discussions should be informal discussions, NOT research papers. If you MUST directly quote a resource, then cite it properly. However, I would much rather simply read your words.

The dicussion should be ZERO PLAGARISM

The Dicussion should be more that 300 words

I need the comments for the other students too

Case Study 1: Should a Computer Grade Your Essays?

1)Identify the kinds of systems described in this case.

2)What are the benefits of automated essay grading? What are the drawbacks?

3)What management, organization, and technology factor should be considered when deciding whether to use AES?

Case Study 2: American Water Keeps Data Flowing

• How did implementing a data warehouse help American Water move toward a more centralized organization?
• Give some examples of problems that would have occurred at American Water if its data were not “clean”?
• How did American Water’s data warehouse improve operations and management decision making?

1. Do the following: • Download Wireshark. • Start Wireshark. • Turn on Wireshark capture. • Type a URL in your browser window (not Wikipedia.org). • After a few seconds, stop the capture. • Answer the following questions:

1a. What URL did you use? What was the IP address of the webserver?

1b. Find the frame in which your PC sent the SYN packet. List the source and destination IP address, the source and destination port numbers, and the header checksum.

1c. Select the SYN/ACK packet. List the source and destination IP address, the source and destination port numbers, and the header checksum.

1d. Select the packet that acknowledges the SYN/ACK segment. List the source and destination IP address, the source and destination port numbers, and the header checksum.

2. Change the options so that only packets you send are recorded. Do a capture. Click on the window containing Wireshark and hit Alt-Enter. This captures the window to your clipboard. Paste it into your homework.

Physical Security Threats Case Study

This case study builds upon your Unit VII Case Study assignment, whichshould be reviewed, along with the professor’s feedback, before completingthis assignment.

Now that your client’s network is up and running, it is time to consider thethreats. For the purpose of this assignment, assume the network is located inthe area where you currently live (or have lived).

First, briefly summarize the three physical threat categories based on yourlocation and what techniques you could use to mitigate them for your client’snetwork:

• natural threats,
• human threats, and
• controlled access threats.

Next, discuss how you would secure the wireless communications component tothe network.

Last, Identify two techniques and/or tools that should be used whendeveloping a system solution for your client.

Your case study should be at least one page in length, not counting thetitle page and reference page. Your paper should be double-spaced, use12-point size Times New Roman font, and contain one-inch margins. Sectionheadings are encouraged to help organize your paper. Your paper must bewritten using APA format. You must cite at least one academic source, whichcan include one of your e-textbooks.
