Answer:
Domain = {Jacinda, Alana, Alexa, Rydel}
Range = {Jody, Rosa, Alia, Alice, Maire}
Explanation:
Domain refers to the set of input values of the function and range refers to the set of output values of the function for the given domain.
Given relation is as follows:
{(Jacinda, Jody), (Alana, Rosa), (Alana, Alia), (Alexa, Alice), (Rydel, Maire)}
Therefore,
Domain = {Jacinda, Alana, Alexa, Rydel}
Range = {Jody, Rosa, Alia, Alice, Maire}
Jenn wants to assign a value to the favorite car variable: favoriteCar = Toyota but gets an error message. What does she need to fix for the code to work?
a
Add a space between the words in the variable name.
b
Create a shorter variable name.
c
Remove the equal sign.
d
Put quotation marks around the string.
Answer:
The correct answer is:
Option D: Put Quotation marks around the string
Explanation:
There are various data types that are used to store data in programming i.e. numeric, alphabetic, alphanumeric etc.
Given that Jenn wants to store the value in variable. The names of cars are usually rods and the data type for them is string.
Whenever a string is used, quotation marks are used around it. The quotation marks make it easier for the compilers and interpreters to identify string.
Hence,
The correct answer is:
Option D: Put Quotation marks around the string
Suppose you have data that should not be lost on disk failure, and the application is write-intensive. How would you store the data?
Answer:
use RAID 5
Explanation:
The best option in this scenario would be to use RAID 5, this would all but eliminate the risk of losing the data. As you would need at atleast 3 seperate drives which would all act as backups for each other. Therefore, in the unlikely case that one of the drives were to fail or data were to become corrupt/lost the other drives would have a backup of that data which ca be used.

The cardinality of the friend_of relationship set between two student entities in the student entity set should be:
Answer:
One to One Relationship
Explanation:
Given that in a computer systems analysis about an entity-relationship model, a one-to-one relationship is a form of cardinality that involves the relationship that exists between two different entities Y and Z, such that one element Y can only be associated with one element Z, or in the other way round.
Hence, the cardinality of the friend_of relationship set between two student entities in the student entity set should be: "One to One Relationship"

Write a public member function which replace that replaces one occurrence of a given item in the ArrayBag with another passed as an argument. The method should return a boolean to indicate whether the replacement was successful.
Answer:
The method is written in Java
public static boolean abc(int [] ArrayBag,int num, int replace){
Boolean done = false;
for(int i =0; i<ArrayBag.length;i++){
if(ArrayBag[i] == num){
ArrayBag[i] = replace;
done = true;
}
}
for(int i = 0;i<ArrayBag.length;i++){
System.out.println(ArrayBag[i]+" ");
}
return done;
}
Explanation:
The method is written in java
The arguments of the method are:
1. ArrayBag -> The array declares as integer
2. num -> The array element to check the presence
3. replace - > The replacement variable
This line defines the method as boolean.
public static boolean abc(int [] ArrayBag,int num, int replace){
This line declares a boolean variable as false
Boolean done = false;
The following iterates through the elements of the array
for(int i =0; i<ArrayBag.length;i++){
This checks if the array element exist
if(ArrayBag[i] == num){
If yes, the array element is replaced
ArrayBag[i] = replace;
The boolean variable is updated from false to true
done = true;
}
}
The following iteration prints the elements of the array
for(int i = 0;i<ArrayBag.length;i++){
System.out.println(ArrayBag[i]+" ");
}
This prints returns the boolean thats indicates if replacement was done or not.
return done;
}
Attached to this solution is the program source file that includes the main method of the program

Your network has been having problems lately when users are participating in video conferences - the video and audio stutters very badly, to the point that the users in building 143 can't even follow what is being said. When you use OmniPeek to investigate, you discover that the link between buildings 147 and 143 is consistently at 90% usage during that period. What should be your next step
Answer:
add a secondary link between buildings 147 and 143
Explanation:
Since the link is consistently showing 90% usage it means that the line is completely congested and data is being slowed due to large amounts of traffic. The best solution would be to add a secondary link between buildings 147 and 143 and divide the users between both links. That would divide the traffic and ultimately speed up the data transfer through these links drastically as they will no longer be congested.

Write a function addFractions that takes as input four integers representing the numerators and denominators of two fractions, adds the fractions, and returns the numerator and denominator of the result. Note that this function should have a total of six parameters. Hint: a/b + c/d = (ad+bc)/bd.
Answer:
The function is written in Python:
def addFractions(a,b,c,d):
num = a*d + b*c
denom = b * d
return [num, denom]
a = int(input("Numerator 1: "))
b = int(input("Denominator 1: "))
c = int(input("Numerator 2: "))
d = int(input("Denominator 2: "))
print(addFractions(a,b,c,d))
Explanation:
The program is written in Python and I also include the main of the program
This defines the function
def addFractions(a,b,c,d):
This calculates the numerator
num = a*d + b*c
This calulates the denominator
denom = b * d
This returns the numerator and the denominator
return [num, denom]
The main starts here
This prompts user for the numerator of the first fraction
a = int(input("Numerator 1: "))
This prompts user for the denominator of the first fraction
b = int(input("Denominator 1: "))
This prompts user for the numerator of the second fraction
c = int(input("Numerator 2: "))
This prompts user for the denominator of the second fraction
d = int(input("Denominator 2: "))
This pass arguments to the function
print(addFractions(a,b,c,d))

LAN spreads throughout a local community and therefore could be connected to server machines within the same long separation, so limited that this only encompasses the department as well as property around which the LAN was already constructed.Implement the Tollable interface.

Programs for embedded devices are often written in assembly language. Some embedded processors have limited instructions, like MARIE. Create a MARIE program which determines whether a given address is a cache hit or not. For this assignment, the cache is 2-way set associative, addresses are 8 bits, blocks are 8 bytes, and the cache has 8 blocks.
Requirements
1. The program must be written in MARIE.
2. The input is a hex address (2 hex digits), the output is 1 for a cache hit and 0 for a cache miss.
3. The cache table is
Set 0 1 5
Set 1 2 4
Set 2 3 2
Set 3 6 0
4. Unlike a real memory system, for this assignment, the cache table won’t change on a cache miss.
Hints: 1.
You have already written a multiply subroutine for MARIE. You could use a similar integer divide subroutine for this. It could return both a quotient and a remainder.
2. I recommend writing this in Java or C++ first to test your algorithm. Write the divide method using repeated subtraction as you will in MARIE.
3. The textbook describes the LoadI instruction, but the MARIE simulator does not recognize that. You can accomplish the same thing using Clear and AddI.
Upload: Your MARIE source file (.mas)
Sample Output
Input: B5, Output: 0
Input: A5, Output: 1
Input: 6C, Output: 0
Input: 7D, Output: 0

for (int i < 0; i < 8; i++){
if (address[0] == '0'){

}
}
if(address[1]>='0' && address[1]<'8'){

} else if(address[1]=='8'|| address[1]=='9'||(address[1]>='a' && address[1]<='f')){
secondBit = 1;
} else{
cout<<"The Hex number is not valid"<< endl;
return 0;
}
setNumber = firstBit * 2 + secondBit;
if(cache[setNumber][0]==tag || cache[setNumber][1]==tag){
cout<<"There is a hit";
} else{
cout<< "There is a miss";
}
return 0;
}
Explanation:
The C++ source code prompts the user for an input for the address variable, then the nested if statement is used to assign the value of the firstBit value given the value in the first index in the address character array. Another if statement is used to assign the value for the secondBit and then the setNumber is calculated.
If the setNumber is equal to the tag bit, Then the hit message is printed but a miss message is printed if not.
