A computer's power supply converts mains AC to low-voltage regulated DC power for the internal components of a computer. You are building a new computer. You are deciding which type of power supply to install. Which of the following definitions BEST describes a valid type of power supply?
- A single-rail power supply provides one rail (PCB trace). This provides the best safety for the computer by providing a single point of shutdown in the event of a short circuit.
- A single-rail power supply provides one rail (PCB trace) used to always provide equal wattage to all devices attached to the power supply.
- A dual-rail power supply provides separate rails (PCB traces) used to balance the power load between multiple circuits, which prevents any one circuit from becoming overloaded.
- A dual-rail power supply provides separate rails (PCB traces) used to provide equal wattage to the devices attached to each rail.

The correct definition of a dual-rail power supply is: "A dual-rail power supply provides separate rails (PCB traces) used to balance the power load between multiple circuits, which prevents any one circuit from becoming overloaded."

In general, dual-rail power supplies are preferred for computers because they offer better power management and can help prevent short circuits or other issues that can damage the computer's components. However, single-rail power supplies can also be used in some cases, depending on the specific power requirements of the computer's components. A dual-rail power supply is a type of power supply that provides separate rails, or PCB traces, for distributing power to the components of a computer. These separate rails are used to balance the power load between multiple circuits, which can help prevent any one circuit from becoming overloaded.

Suppose you are choosing between the following three algorithms:
• Algorithm A solves problems by dividing them into five subproblems of half the size, recursively solving each subproblem, and then combining the solutions in linear time.
• Algorithm B solves problems of size n by recursively solving two subproblems of size n − 1 and then combining the solutions in constant time.
• Algorithm C solves problems of size n by dividing them into nine sub-problems of size n=3, recursively solving each sub-problem, and then combining the solutions in O(n2) time.
What are the running times of each of these algorithms (in big-O notation), and which would you choose?

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers.
For this program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow.
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print('{:.2f}'.format(your_value))
Ex: If the input is:
5 30.0 50.0 10.0 100.0 65.0
the output is:
0.30 0.50 0.10 1.00 0.65
The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.
For coding simplicity, follow every output value by a space, including the last one

An example of a host-based intrusion detection tool is the tripwire program. This is a file integrity checking tool that scans files and directories on the system on a regular basis and notifies the administrator of any changes. It uses a protected database of cryptographic checksums for each file checked and compares this value with that recomputed on each file as it is scanned. It must be configured with a list of files and directories to check and what changes, if any, are permissible to each. It can allow, for example, log files to have new entries appended, but not for existing entries to be changed. What are the advantages and disadvantages of using such a tool? Consider the problem of determining which files should only change rarely, which files may change more often and how, and which change frequently and hence cannot be checked. Hence consider the amount of work in both the configuration of the program and on the system administrator monitoring the responses generated.

Problem 1:


Create a Class named Array2D with two instance methods:


public double[] rowAvg(int[][] array)


This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per row of the 2D array argument.


The method will adjust automatically to different sizes of rectangular 2D arrays.


Example: Using the following array for testing:


int [][] testArray =

{

{ 1, 2, 3, 4, 6},

{ 6, 7, 8, 9, 11},

{11, 12, 13, 14, 16}

};

must yield the following results:


Averages per row 1 : 3.20

Averages per row 2 : 8.20

Averages per row 3 : 13.20

While using this other array:


double[][] testArray =

{

{1, 2},

{4, 5},

{7, 8},

{3, 4}

};


must yield the following results:


Averages per row 1 : 1.50

Averages per row 2 : 4.50

Averages per row 3 : 7.50

Averages per row 4 : 3.50

public double[] colAvg(int[][] array)


This method will receive a 2D array of integers, and will return a 1D array of doubles containing the average per column of the 2D array argument.


The method will adjust automatically to different sizes of rectangular 2D arrays.


Example: Using the following array for testing:


int [][] testArray =

{

{ 1, 2, 3, 4, 6},

{ 6, 7, 8, 9, 11},

{11, 12, 13, 14, 16}

};

must yield the following results:


Averages per column 1: 6.00

Averages per column 2: 7.00

Averages per column 3: 8.00

Averages per column 4: 9.00

Averages per column 5: 11.00

While using this other array:


double[][] testArray =

{

{1, 2},

{4, 5},

{7, 8},

{3, 4}

};


must yield the following results:


Averages per column 1: 3.75

Averages per column 2: 4.75



My code is:


public class ArrayDemo2dd

{


public static void main(String[] args)

{

int [][] testArray1 =

{

{1, 2, 3, 4, 6},

{6, 7, 8, 9, 11},

{11, 12, 13, 14, 16}

};

int[][] testArray2 =

{

{1, 2 },

{4, 5},

{7, 8},

{3,4}

};


// The outer loop drives through the array row by row

// testArray1.length has the number of rows or the array

for (int row =0; row < testArray1.length; row++)

{

double sum =0;

// The inner loop uses the same row, then traverses all the columns of that row.

// testArray1[row].length has the number of columns of each row.

for(int col =0 ; col < testArray1[row].length; col++)

{

// An accumulator adds all the elements of each row

sum = sum + testArray1[row][col];

}

//The average per row is calculated dividing the total by the number of columns

System.out.println(sum/testArray1[row].length);

}

} // end of main()


}// end of class

Earl develops a virus tester which is very good. It detects and repairs all known viruses. He makes the software and its source code available on the web for free and he also publishes an article on it. Jake reads the article and downloads a copy. He figures out how it works, downloads the source code and makes several changes to enhance it. After this, Jake sends Earl a copy of the modified software together with an explanation. Jake then puts a copy on the web, explains what he has done and gives appropriate credit to Earl.
Discuss whether or not you think Earl or Jake has done anything wrong?
