1 :

Write the header file Car.h for the Car class. The Car class has three data members: miles_per_gallon (double), fuel (double), and model (string). The Car class has a constructor that initializes each data member.  The Car class has four additional member functions:

 

get_model : no parameters, returns model

drive : double miles parameter, returns nothing

add_fuel : double gallons parameter, returns nothing

low_on_fuel : no parameters, returns true or false

Do not provide the implementation of the member functions.

 

2:

Write the source code file

Square.cpp

. Include necessary header files and implementation of each member function of the following

Square

class.    

 

class Square

{

public:

    Square(double initial_length, string initial_color);

    doubleget_length() const;

    stringget_color() const;

    doubleget_area() const;

private:

    double length;

    string color;

};

 

The area of a square is length x length.

 

 

3:

Write a void function named sort2 that takes two string parameters and sorts them. The function swaps the values of the string parameters if the 1^st string is lexicographically greater than the 2^nd string and otherwise leaves the strings unchanged. For example:

 

string s1 = “Orange”;

string s2 = “Apple”;

sort2(s1, s2);      // now s1 is “Apple” and s2 is “orange”

 

 

 Net Neutrality

Read four (4) academically reviewed articles on Net Neutrality and complete the following activities:

(Wikipedia articles will not be accepted. Professor may check originality of all posts. Avoid copy-and-paste.

1.     Summarize all four (4) articles in 300 words or more. Please use your own words. No copy-and-paste

2.     Base on your article review and the assigned reading, discuss how net neutrality will affect data networks and the availability of information to businesses. Do you believe net neutrality will lead to IT efficiency? Why or why not? 

Please use APA throughout. And Add references.

Consider the following scenarios and on the basis of your understanding of these scenarios, create a report in a Microsoft Word document, answering the given questions:

 

Alex is a Network Administrator and keeps receiving a number of queries from his team members especially when they are not able to handle user calls. A few of these are listed below:

 

• A user calls and says that she is able to work on all applications except Internet explorer web browsing. When she tries to access a website, she receives this error: “Page cannot be displayed—cannot find server or DNS error.”
• What can be the cause of the problem and on which layers can the problem exist? Provide possible solutions to each cause of the problem.
• List the various troubleshooting steps that Alex should conduct to resolve the issue, assuming he approaches the most common error first and the least common error last.
• Another user who manages a tremendous amount of data on a daily basis has encountered a network problem. He has an idea that the problem is related to usage of TCP and UDP.
• How is data transmitted through the different layers of the TCP and UDP? Describe the specific layers in which data is transmitted using TCP and UDP.
• Do you agree with this statement that “TCP is always more reliable than UDP?” Why or why not? List and compare the security considerations of both the data transfer techniques.
• Can TCP and UDP be used interchangeably? Which factors will influence their interchangeable use? Describe the difference of TCP and UDP. Also, list and compare the factors of transmission with respect to the data transmission technique used by them.
