Network Address Translation (NAT), computer science homework help
If your computer can access the Internet, it must use TCP/IP. If you have your own home network with your own router, there is a chance that your computer has an IP address very similar to ours or someone else’s in your class—or the same address, in fact. How can two computers have the same IP address? Well, they can’t. This is a security technique called network address translation (NAT) in which one set of ‘‘private’’ IP addresses is used inside a network and a different set of ‘‘public’’ IP addresses is used by the router when it sends the messages onto the Internet.What is the reasoning and importance of this type of security? Why is it necessary to perform this translation? How might NAT be used to protect large organizations?Must be at least 150 words.

SIT Database Security Related Rules for Staff Members Essay
You are the web master of a college website. You share a server with other school departments such as accounting and HR.Based on this chapter, create at least five security-related rules for staff members who are adding web pages being added to your site. Include a justification and explanation for each rule. Rules should relate to college, staff and student, and system information security.

Columbia University Chapters 1 & 2 Computer Hardware & Computer Software Questions
Assignment: Chapters 1 & 2 QuestionsIntroductionPrepare written answers to, and be prepared to discuss each of the following questions, each of which is taken from the correspondingly numbered exercise question from the Computational Thinking for the Modern Problem Solver text. Chapter 1:Question 2. What is the difference between computer hardware and computer software? Provide multiple examples of each. Question 4. Digital cameras are one kind of modern computer. In this sense, answer the following questions.How does the user supply input to a digital camera?What would you consider to be the camera’s output device(s)?What is the purpose of the camera’s memory? Question 6. In what ways do the GUI elements of a smartphone or tablet computer typically differ from those of a laptop or desktop computer? In what ways are they similar?Question 7. Applying Moore’s law, how much larger would you expect a computer from 30 years ago to be by comparison to the computer you currently use? What are the specifications of the computer you currently use?____________________________________________________________________________________________________________Chapter 2:Question 3. If “tax day” is represented as 04/15 (corresponding to the fifteenth day of the fourth month, or April 15th) then using the comparable representation of the day of the year you were born (i.e. your birthday) provide the equivalent representation of that value in each of the following systems.Tally mark number systemRoman number systemBinary number systemQuestion 5. For each quantity listed, indicate whether the quantity is continuous or discrete.Day of the weekFlying speed of a hummingbirdNumber of peas in a pea podLength of a commencement speechNumber of chapters in a bookNumber of commas in a bookWeight of a bookAge of a book Question 7. How many unique patterns does a sequence of 5 bits generate? Question 8. How many unique patterns does a sequence of N bits generate?Question 9. For each quantity listed, give the number of bits that would be required to represent that data in a computing system.The monthA class grade, where class grades must be one of A, B, C, D, F, or I.An MPAA movie rating. The MPAA rates movies as one of the following: G, PG, PG-13, R, NC-17.The track number of a song on an MP3 album. The most tracks that can be put on an MP3 album is 100.The day of the year. There are 365 days in a year (except for leap years in which there are 366 days). For example, January 1 would be day 1, while December 31 would be day 365 for non-leap years and day 366 for leap years.One nucleobase of a DNA string. There are only four nucleobases in this question: adenine (A), guanine (G), cytosine (C), and thymine (T).Describe an additional kind of data, ideally something specific to the domain of your earlier studies or work environment, and then give the number of bits that would be required to represent that data in a computing system. Question 11. Consider a black-and-white picture that consists of 9 columns and 12 rows of pixels. The picture is encoded using the following run-length encoding where a forward slash (/) denotes the end of a row, as illustrated in Figure 2.21. 0,8/1,3,4/2,2/2,2/2,2,3,1/2,6/2,2,3,1/2,2/2,2/2,2/2,2/1,4Render the picture on this grid/table and submit to the Dropbox:Question 11 - table Assignment: Process DescriptionIntroductionConsider a simplistic tally mark number system, similar to the one illustrated in Figure 2.8 of the Computational Thinking for the Modern Problem Solver text. In this system a number is represented by one tally mark (■ is used here) for each unit in the number. The larger the number the longer the representation; thus 17 would be represented as ■■■■■■■■■■■■■■■■■, which is unwieldy but precise. For this assignment, you are to consider the process of performing the addition of two numbers represented in the tally mark system and you are to develop a precise description of it. Although this computational process may seem apparent, the real challenge is to describe it precisely and completely enough that it could be carried out generally by an agent of limited capability. It might be useful to imagine explaining this process to a very young child. You may even find it useful to think of two egg cartons, possibly with eggs in them, and a third carton into which all of the eggs are to be placed. Or possibly, think of graph paper rather than tally marks placed on a sheet of blank paper. You see, the processor of a computer is really an agent of limited capability, and the memory of a computer simply provides standard sized places to store representations. So, consider three containers, each with 32 slots, named Number1, Number2 and Sum respectively. Use this terminology to formulate a description; you may find it appropriate to express your description as a sequence of steps rather than as a paragraph. Keep in mind that the process you describe must work for all valid cases, and not just the one example illustrated below.

Needing help with this assignment please!
Give an example of where session
management should be used in an online application. Web pages are
typically requested distinctly and not as a group or even identified by
user. How does this feature change when session management is enacted?
In your example, what would happen to the system without session
management? Suggest how this system could be compromised by an attacker
if session management was not used.Give an example showing
why authentication is necessary as a point of entry into an
application. What type of information is being protected by
authentication in this case? What levels of users can you imagine for
this example? What would happen if authentication was not used in this
example? Justify your answers.Give an example of where passwords could be stored
safely in an online application. How would you suggest protecting them
from accidental or brute-force discovery? What other modifications
would you include to protect the passwords from compromise? Justify
your answers.
