You have seen that the math library contains a function that computes the square root of numbers. In this exercise, you are to write your own algorithm for computing square roots. One way to solve this problem is to use a guess-and-check approach. You first guess what the square root might be and then see how close your guess is. You can use this information to make another guess and continue guessing until you have found the square root (or a close approximation to it). One particularly good way of making guesses is to use Newton's method. Suppose x is the number we want the root of and guess is the current guessed answer. The guess can be improved by using as the next guess.
Write a program that implements Newton's method. The program should prompt the user for the value to find the square root of (x) and the number of times to improve the guess. Starting with a guess value of x/2, your program should loop the specified number of times applying Newton's method and report the final value of guess. You should also subtract your estimate from the value of math.sqrt(x) to show how close it is.
Two CSMA/CD stations are each trying to transmit long (multiframe) files. After each frame is sent, they contend for the channel, using the binary exponential backoff algorithm.
Description: Part 2 is a new piece of work that should not include material from Part 1. As before, it is a written analysis (4500 words) of a complex ethical problem similar to that which you might encounter in the IT industry.
Discuss whether you should accept this demand from your manager or whether you should persuade your team to give their time to the organization rather than to their families.
In your opinion, what are the three biggest challenges in planning and designing a solution for a programming problem? What can you do to overcome these challenges? How would you apply these techniques to the programs in this class?
Suppose Y now sends to X. Which bridges learn where Y is? Does Z's network interface see this packet?
a) Write an equation to model the problem. Let x represent the number of video game rentals.
For the network given in Figure 3.34, give the datagram forwarding table for each node. The links are labelled with relative costs; your tables should forward each packet via the lowest-cost path to its destination.
Explain the importance of demonstrating the communication skills needed for effective use of the telephone?

What compression ratio does the encoder believe has been achieved by this method?
If the organization has three information assets to estimate for risk management purposes which vulnerability must be estimated for additional controls first? Which vulnerability must be evaluated last?
Selection can also be performed on bags. Give a Map Reduce implementation that produces the proper number of copies of each tuple t that passes the selection condition. That is, produce key-value pairs from which the correct result of the selectio..
