Give an input file of student records in the following format:

<name>#<SID>#<major>#<GPA>

Smith Eugene#A9S65A#Chemistry#2.50
Brown Ezra#T56G0M#Business Administration#1.36
Brown Ferman#PI56T4#Accounting#2.68
Chavis Ertle#7HS56#Chemistry#3.00
Strickland DiChildersa#TWH54F#Business Administration#2.00
Stone Clark#BN78N3W#English#4.00
Childers Evelyn#U8M8N2#Criminal Justice#2.73
Stone Desmond#JHD9K2#Computer Science#3.23

Write a Java application to process the input file of student information. Design your solution using classes for student, student Database, and a driver class. Your application should output the average GPA and display the student list in the descending order of their GPA.

Telemedicine

Telemedicine has become progressively important, since there is an increased demand for chronic diseases treatment. Nowadays, with this advance technology, doctors can provide consultations to patients using FaceTime or Skype on mobile devices. Moreover, they are also able to access medical examination reports from database and send prescriptions to patients’ pharmacies, without meeting the patients face to face. However, telemedicine is still at the beginning stage with only $200 million of revenue yearly. According to healthcare experts, they predict telemedicine will increase annual revenue to $2 billion for a few years down the road.

Question 1 [15 marks - NOT more than 200 words] To marketers, what role has mobile technology played in evolution of this industry? Explain.

Information is data that is framed in a specific context. In this sense, information is contextual data that has a level of inherent value. Data might be the binary 0s and 1s on a hard drive, but information is the combination of that binary data into a document, media file, or database. Therefore, information systems are methods of managing the value of different types of data. The value of the data might be in the personal records such as social security number, addresses, or shopping habits that are linked together to form an online shopping cart and on-click purchasing. The value of information provides for the potential for ethical, social, and political issues within an organization. An example of these ethical, social, and political issues can be found in the concept of privacy.

What ethical, social, and political issues arise with the use of information systems ?

Select a dataset that is publicly available on the Internet, such as the Census Bureau, any government database, any of the databases used in this class or in prior courses to date, or any nonprofit databases that are publicly available.

Using the data set, identify a research question that you want to study. Using the dataset you located, review the type of data that is included in the set. Then, think of a possible research question, using the data provided, that you may want to ask and then research.

Then, use at least 2 variables and an n value of 20 for each variable to run analysis and draw conclusions based on the data. Be sure that you answer your research question in your analysis.

Length: 2-3 pages

1. Suppose an attacker obtained 128 bits of ciphertext that were encrypted using an encryption algorithm whose keys are known to be 128 bits long. How effective is an exhaustive key search if the attacker does not know the encryption algorithm used?

1. Provide an example of when data integrity is more important than data confidentiality?

1. Suppose you have been asked at your new job to recommend the strength of encryption needed to protect the contents of a database. Draw up a list of some of the questions you think you will need to answer before you can meaningfully attempt to establish a notion of practical security for this application?

1. When evaluating security, how would you apply the concepts of Theoretical Security versus Practical Security?
