Answer:

No-force policy

Explanation:

The policy that allows a transaction to commit even if it has modified some blocks that have not yet been written back to disk is called the _NO-FORCE_ policy.

In data theory, the No-Force Policy is beneficial for the control of transaction. In this policy, when a transaction commits, changes that are made are not required to be written to disk in place. The changes recorded are preserved in order to make transaction durable. The recorded changes must be preserved at commit time.

Elements of Server software that is built-in, in Windows workstations are:

1. Hard drives,

2. RAM (Random Access Memory)

3. Processors

4. Network adapters.

Windows Professional OS is not considered a server due to the following:

1. Windows Professional OS has a limit on the number of client connections it allowed.

2. Unlike Server, Professional OS uses less memory

2. In comparison to Server, Professional OS uses the CPU less efficiently

4. Professional OS is not built to process background tasks, unlike Server that is configured to perform background tasks.

Count

Explanation:

Let's see which function does what:

SUM

COUNT

SQRT

SORT

As we see, Count is the function that gets the number of entries.

Answer:

Explanation:

Tells how many numeric entries are there.

Answer:

Here is the complete function:

void MakeSentenceExcited(char* sentenceText) {  // function that takes the text as parameter and replaces any period by an exclamation point in that text

int size = strlen(sentenceText);  //returns the length of sentenceText string and assigns it to size variable

char * ptr;  // character type pointer ptr

ptr = sentenceText;  // ptr points to the sentenceText string

for (int i=0; i<size; i++){  //iterates through the sentenceText string using i as an index

    if (sentenceText[i]=='.'){  // if the character at i-th index of sentenceText is a period

        sentenceText[i]='!'; } } } //places exclamation mark when it finds a period at i-th index of sentenceText

Explanation:

The program works as follows:

Suppose we have the string:

sentenceText = "Hello. I'm Miley. Nice to meet you."

The MakeSentenceExcited method takes this sentenceText as parameter

int size = strlen(sentenceText) this returns the length of sentenceText

The size of sentenceText is 35 as this string contains 35 characters

size =  35

Then a pointer ptr is declared which is set to point to sentenceText

for (int i=0; i<size; i++) loop works as follows:    

1st iteration:

i=0

i<size is true because i=0 and size = 35 so 0<35

So the body of loop executes:

 if (sentenceText[i]=='.') statement checks :

if (sentenceText[0]=='.')

The first element of sentenceText is H

H is not a period sign so the statement inside if statement does not execute and value of i increments to 1. Now i = 1

2nd iteration:

i=1

i<size is true because i=1 and size = 35 so 1<35

So the body of loop executes:

 if (sentenceText[i]=='.') statement checks :

if (sentenceText[1]=='.')

This is the second element of sentenceText i.e. e

e is not a period sign so the statement inside if statement does not execute and value of i increments to 1. Now i = 2

So at each iteration the if condition checks if the character at i-th index of string sentenceText is a period.

Now lets see a case where the element at i-th index is a period:

6th iteration:

i=5

i<size is true because i=5 and size = 35 so 5<35

So the body of loop executes:

 if (sentenceText[i]=='.') statement checks :

if (sentenceText[5]=='.')

This is the character at 5th index of sentenceText i.e. "."

So the if condition evaluates to true and the statement inside if part executes:

sentenceText[i]='!'; statement becomes:

sentenceText[5]='!'; this means that the character at 5th position of sentenceText string is assigned an exclamation mark.

So from above 6 iterations the result is:

Hello!

This loop continues to execute until all the characters of sentenceText are checked and when the value of i gets greater than or equal to the length of sentenceText then the loop breaks.

def color_translator(color):

      if color == "red":

             hex_color = "#ff0000"

      elif color == "green":

             hex_color = "#00ff00"

      elif color == "blue":

             hex_color = "#0000ff"

      else:

             hex_color = "unknown"

      return hex_color

Explanation:

Since the parameter in the above function is color,

This variable will serve as the name of a color and it'll be used in the conditional statements to check if the name of color is any of red, green and blue;

And that is why we have

if color == "red":

elif color == "green":

elif color == "blue":

The variable used to hold the color codes, hex_color, will be returned at the end of the function and that's why we have

return hex_color

When the program is tested with print(color_translator("blue")) and others, it prints the desired output

Answer:

Here is the recursive function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num.

def sumSquares(num):

   if(num >= 0):  # checks if the value of num is less than or equal to 0

       if (num==0):  #if value of num is 0

           return 0  #returns 0 if value of num is 0

       else:  #if value of num is greater than 0

           return sumSquares(num - 1)+ num * num  #recursively calls the sumSquares method to return the sum of squares of numbers from 1 to num

   else:  # if a user enters a negative num

       (print("The number if not positive"))  #prints this message

       exit()  # exits after displaying that number if not positive message

#below print statement is used in order to check the working of the function        

print(sumSquares(3)) #calls function and passes value 3 for num

Explanation:

The program works as follows:

The function sumSquares(num) that takes an integer num as parameter and returns the sum of squares of numbers from 1 to num

The first if condition checks if value of num is positive. If this condition evaluates to true then the another if statement inside this if statement is executed which checks if the value of num is 0. If this condition evaluates to true then the program returns 0. However if this condition evaluates to false then the else part executes which has the following statement:

return sumSquares(num - 1) + num * num

For example num = 3

so the above recursive statement works as follows:

sumSquares(3-1) + 3 * 3

sumSquares(2) + 9

Note that the sumSquares() method is called again and the value 2 is passed as num. As 2 is greater than 0. So again the recursive statement executes:

sumSquares(2 - 1) + 2 * 2 + 9

sumSquares(1) + 4 + 9

sumSquares(1) + 13

sumSquare() method is called again and the value 1 is passed as num. As 1 is greater than 0. So again the recursive statement executes:

sumSquares(1 - 1) + 1 * 1 + 13

sumSquares(0) + 1 + 13

sumSquares(0) + 14

sumSquare() method is called again and the value 0 is passed as num

As the value of num=0 So the if (num == 0):  condition evaluates to true and the statement returns 0 executes which returns 0:

sumSquares(0) + 14

0 + 14

Hence the output is:

14

Answer:

Here is the Python program:

def scores(file):  # method scores that takes a file name as parameter and returns the sum and average of scores in a file

   with open(file, 'r') as infile:  # open the file in read mode

       lines = [score.split() for score in infile]  # split the scores into a list

       print("The scores are:",lines)  #print the scores

       for line in lines:  # loops through each score

           total= sum(int(score) for score in line)  # adds the scores

           average =total/len(line) # computes average by taking sum of scores and dividing by number of scores in file

       print("The sum is:", total)  #prints the sum of scores

       print("The average is:", "{:.2f}".format(average))   #prints the average

filename = input("Enter name of the file: ")  #prompts user to enter name of file

scores(filename) #calls scores method by passing the file name to it in order to compute sum and average of file contents i.e. scores

Explanation:

It is assumed that the scores in the file are separated by a blank space.

The scores() method takes a file name as parameter. Then it opens that input file in read mode using object infile.

split() method is used to split the scores in a file into a list. Suppose the scores are 1 2 3 4 5 6 . So after the split, they become ['1', '2', '3', '4', '5', '6']  

The loop iterates through each score in the file, splits them into a list and stores this list in lines. The next print statement prints these scores in a list.

The second loop for line in lines iterates through each score of the list and the statements: total= sum(int(score) for score in line)  and average =total/len(line) computes the total and average of scores.

total= sum(int(score) for score in line)  statement works as follows:

for loop iterates through each element of list i.e. each score

int() converts that string element into integer.

sum() method adds the integers to compute their total.

So if we have  ['1', '2', '3', '4', '5', '6']  each element i.e. 1,2,3,4,5,6 is converted to integer by int() and then added together by sum method. So this becomes 1+2+3+4+5+6 = 21. This result is stored in total. Hence

total = 21.

average = total/len(line) works as follows:

The computed sum of scores stored in total is divided by the number of scores. The number of scores is computed by using len() method which returns the length of the line list. So len() returns 6. Hence

average = total/len(line)

              = 21 / 6

average = 3.5

The next two print statement prints the value of sum and average and "{:.2f}".format(average)) prints the value of average up to 2 decimal places.

Answer:

Here is the Python program:

user_tweet = input()

decoded_tweet = user_tweet.replace('TTYL', 'talk to you later')

print(decoded_tweet)

Explanation:

The program works as follows:

Suppose the input is:    'Gotta go. I will TTYL'

This is stored in user_tweet. So

user_tweet = 'Gotta go. I will TTYL'

The statement: user_tweet.replace('TTYL', 'talk to you later')  uses replace() method which is used to replace a specified string i.e. TTYL with another specified string i.e. talk to you later in the string stored in user_tweet.

The first argument of this method replace() is the string or phrase that is to be replaced and the second argument is the string or phrase that is to replace that specified string in first argument.

So this new string is assigned to decoded_tweet, after replacing 'TTYL' with 'talk to you later' in user_tweet.

So the print statement print(decoded_tweet) displays that new string.

Hence the output is:

Gotta go. I will talk to you later.

Explanation:

Data hazards happen when instructions exhibiting data dependence modify data in the different stages of a pipeline. Potential data hazards when not attended to, can result in race hazards or race conditions. Examples of situations where data hazards can occur is read after write, write after read, write after write. To resolve data hazards we can insert a pipeline whenever a read after write, dependence is encountered, use out-of-order execution or use operand forwarding.

Structural hazards happen when multiple instructions which are already in pipeline new the same resource. Example is a situation which many instructions are ready to execute an there is a single Arithmetic Logic Unit. Methods for preventing this hazard include pipeline break an pipeline flushing.

Answer:

B. Containerization.

Explanation:

In this scenario, management wants to ensure any sensitive data on company-provided cell phones is isolated in a single location that can be remotely wiped if the phone is lost. The technology which best meets this need is containerization.

In Computer science, containerization can be defined as a process through which software applications are used or operated in an isolated space (environment). It uses an operating system level virtualization method, such as a single host OS kernel, UFS, namespaces, Cgroups, to run software applications.

Hence, using the containerization technology makes it easy to wipe off the cell phones if lost because it is isolated in a single location.

Answer:

the higher order bits in AL will be true

Explanation:

We know from the truth table that in an OR operation, once one operand is true the result is true, no matter the value of the other operand. From the above AL will have the higher order bits to be true since the first four higher order bits are 1s, 1111_0000, this is regardless of the original values of AL. We cannot however ascertain if the lower bits of AL are true from this. Note 1 evaluates to true while 0 is false

Answer:

The programming language is not stated; However, the program written in C++ is as follows: (See Attachment)

#include<iostream>

using namespace std;

string capt(string result)

{

result[0] = toupper(result[0]);

for(int i =0;i<result.length();i++){

 if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' ') {

  result[i+2] = toupper(result[i+2]);

 }

 if(result[i+2]==' ')  {

  result[i+3] = toupper(result[i+3]);

 }

 } }

return result;

}

int main(){

string sentence;

getline(cin,sentence);

cout<<capt(sentence);

return 0;

}

Explanation:

The method to capitalize first letters of string starts here

string capt(string result){

This line capitalizes the first letter of the sentence

result[0] = toupper(result[0]);

This iteration iterates through each letter of the input sentence

for(int i =0;i<result.length();i++){

This checks if the current character is a period (.), a question mark (?) or an exclamation mark (!)

if(result[i]=='.' || result[i]=='?' ||result[i]=='!')  {

 if(result[i+1]==' '){  ->This condition checks if the sentence is single spaced

  result[i+2] = toupper(result[i+2]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

 if(result[i+2]==' '){ ->This condition checks if the sentence is double spaced

  result[i+3] = toupper(result[i+3]);

-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized

 }

}

}  The iteration ends here

return result;  ->The new string is returned here.

}

The main method starts here

int main(){

This declares a string variable named sentence

string sentence;

This gets the user input

getline(cin,sentence);

This passes the input string to the method defined above

cout<<capt(sentence);

return 0;

}

Answer:

I am writing the program in JAVA and C++

JAVA:

public int createLicenseNum(int customID){  //class that takes the customID as parameter and creates and returns the licenseNum

       licenseNum = (100000 * customID) + licenseYear;  //licenseNum creation formula

       return(licenseNum);     }

In C++ :

void DogLicense::CreateLicenseNum(int customID){ //class that takes the customID as parameter and creates the licenseNum

licenseNum = (100000 * customID) + licenseYear; } //licenseNum creation formula

Explanation:

createLicenseNum method takes customID as its parameter. The formula inside the function is:

licenseNum = (100000 * customID) + licenseYear;

This multiplies 100000 to the customID and adds the result to the licenseYear and assigns the result of this whole expression to licenseNum.

For example if the SetYear(2014) means the value of licenseYear is set to 2014 and CreateLicenseNum(777) this statement calls createLicenseNum method by passing 777 value as customID to this function. So this means licenseYear = 2014 and customID  = 777

When the CreateLicenseNum function is invoked it computes and returns the value of licenseNum as:

licenseNum = (100000 * customID) + licenseYear;

                     = (100000 * 777) + 2014

                     = 77700000 + 2014

licenseNum = 77702014                                                                                                        

So the output is:

Dog license: 77702014          

To call this function in JAVA:

public class CallDogLicense {

public static void main(String[] args) {//start of main() function

    DogLicense dog1 = new DogLicense();//create instance of Dog class

dog1.setYear(2014); // calls setYear passing 2014

dog1.createLicenseNum(777);// calls createLicenseNum passing 777 as customID value

System.out.println("Dog license: " + dog1.getLicenseNum()); //calls getLicenseNum to get the computed licenceNum value

return; } }

Both the programs along with the output are attached as a screenshot.

Answer:

public int createLicenseNum(int customID){

  licenseNum = (100000 * customID) + licenseYear;

  return(licenseNum);    

}
