- Even an objective computer software can struggle with judging rules. The official rules of football (or soccer, as some people call it) state that the referee may allow play to continue "when the team against which an offence has been committed will benefit from such an advantage" and may penalise "the original offence if the anticipated advantage does not ensue at that time" (Federation Internationale de Football Association 2003).How would you put this rule into action? What are the obstacles involved?The Nobel peace prize is awarded to persons who excel in various fields ofendeavor. Currently only a handful of panel members determine and choose people who qualify for a particular award based on nomination from a wide range of disciplines’. This process of selecting the winners for the various prices have been criticized as being biased especially from the side of the panel members. The committee of experts at a general council meeting decided to automate the selection process. On a trial bases, you have been engaged to develop a java system that will automatically select a nominee as the winner of the award in two categories (peace and science). Your program should have the following functionalities. a) You are to define a class named Nobel_Award. Your class must have twofunctions, one of the functions should be named Award_Category, andthe other function should be named Award_Winner. YourAward_Category must have a string parameter list and return the stringwhen called. Your…Two new computer codes are being developed to prevent unauthorizedaccess to classified information. The first consists of six digits (each chosenfrom 0 to 9); the second consists of three digits (from 0 to 9) followed by twoletters (A to Z, excluding I and O).(i) Which code is better at preventing unauthorized access (defined as breaking the code in one attempt)?(ii) If both codes are implemented, the first followed by the second, what isprobability of gaining access in a single attempt?
- Computer Science Scenario: Suppose you were to let your friend use your computer for a couple of hours in order for them to complete their homework assignments. What kind of precautions would you take before letting them use your computer? In those precautions, what is the logic behind your reasoning? How would your precautions change if this computer was being used by the general public instead?Read the following passage carefully and summarize the writer’s concerns in justone paragraph. The current college behavioural standard is a cool, calm, and copacetic attitude, and this does not help to interest the students in their studies. Mark Edmundson points out in his essay a lack of passion for learning in today‘s students. A show of emotion is strictly forbidden, and to get excited is seen as unfashionable. He blames contemporary society and our consumer mentality for this: You‘re inhibited, except on ordained occasions, from showing emotion, stifled from trying to achieve anything original. You‘re made to feel that even the slightest departure from the reigning code will get you genially ostracized.‘ The image that is portrayed by television and the media in general is a cool, detached look. Students do not display a joy of learning or for expressing oneself. The personal creativity in today‘s academic environment has been severely stifled. There are many causes of this…Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. The annual loss expectancy (ALE) without controls is $ A . The annual loss expectancy (ALE) with controls is $
- Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? Calculate the prior and post ALE and do a cost-benefit analysis to answer the question. In your answer make sure that you indicate what ARO, SLE and ALE are with and without controls. State clearly whether the company should implement the controls and explain why.In the future, when everyone has a home terminal connected to a computer network, instant public referendums on important pending legislation will become possible. Ultimately, existing legislatures could be eliminated, to let the will of the people be expressed directly. The positive aspects of such a direct democracy are fairly obvious; discuss some of the negative aspects.Consider a computer system with three users: Alice, Bob, and Cindy. Alice owns file X, and Bob and Cindy can read it. Bob owns file Y, and Cindy can read and write the file Y, but Alice can only read it. Cindy owns file Z, but neither Alice nor Bob can read or write it. If a user owns a file, he/she can also execute the file. Create the ACM (access control matrix) of the system Show the ACL and CL of the ACM Now Cindy allows Alice to read Z, Alice removes Bob's ability to read X, and Bob removes all the rights of Alice and Cindy to Y. Show the ACM after these changes.
- A student management system is defined below: With the help of the registrar, a new student establishes his/her account. A student can register classes of his/her choosing during the registration period. If the system found there are pre-requisite violations the student will be de- registered from the violating classes. A student who was de-registered up to three times will be warned. A student whose GPA is between 2.0 to 2.3 is also warned. Students who are warned must see the student adviser to remove the warning. A student whose GPA is less than 2.0 or who was warned three times or who has one outstanding warning without seeing the adviser for one semester will be suspended. A student can apply for graduation or transfer to other schools. If the student passed the graduation check by the registrar, she will be put on the list of graduating student. Graduating students whose GPA is higher than 3.5 are put in Dean's list, those higher that 3.9 are put in President's list. Anyone who…If the aforementioned procedures are terminated as a result of reaching a cessation point, the subsequent outcomes will manifest.a. As a user, you may have come across systems with antivirus installed onthem yet the same computer gets infected with malwares. Briefly explains this phenomenon to a lay person. b. Suppose that Bob wants to send a message to Alice. Bob does not want the message be kept secret, however he wants Alice to be able to ascertain that the message is indeed from him. Briefly explain what Bob can do to help Alice ascertain if it’s indeed coming from him and whether the message has not been altered.
