Graphic designers can compress files in different formats. One of the formats ensures that the quality and details of the image are not lost when the graphic designer saves the file. Which file format is this?
The _______file format ensures that images don’t lose their quality and details when graphic designers save them.
Answer: TIFF
Explanation:
Tag Image File Format (TIFF) is the go to file format when one needs to store their image without worrying about it losing its quality and details. This is why TIFF images do not become smaller when compressed because they aim to save the quality of the work.
One has access to options such as tags and transparency on TIFF and it can be used on Photoshop as well as for things like desktop publishing and faxing.
Answer:
The lossless file format ensures that images don’t lose their quality and details when photographers save them.

Compilers can have a profound impact on the performance of an application. Assume that for a program, compiler A results in a dynamic instruction count of 1.0E9 and has an execution time of 1.1 s, while compiler B results in a dynamic instruction count of 1.2E9 and an execution time of 1.5 s. a. Find the average CPI for each program given that the processor has a clock cycle time of 1 ns.
Answer:
The answer is "1.25"
Explanation:
[tex]{CPU \ time}= {instructions \times CPI \times cycle\ time}[/tex]
[tex]\therefore\\\CPI= \frac{CPU \ time}{instructions \times cycle \ time} \\\\cycle \ time = 1 \\\\ns = 10^{-9} s \\[/tex]
Also for this context, it executes the time = CPU time. So, the compiler A, we has
[tex]CPI_{A}= \frac{CPU \ time_{A}} {instructions_{A} \times cycle \ time}= \frac{1.1 s}{10^{9} \times 10^{-9} s}= 1.1[/tex]
For compiler B, we have
[tex]CPI_{B}= \frac{CPU \ times_{B}} {instructions_{B} \times cycle \ time}[/tex]
[tex]= \frac{1.5\ s}{ 1.2 \times 10^{9} \times 10^{-9} \ s}\\\\= \frac{1.5}{ 1.2 }\\\\= 1.25[/tex]
The average CPI for each program given that the processor has a clock cycle time of 1 ns is : 1.1, 1.25.
Average CPI for each programCPI (Complier A)=CPU time/Instruction×Cycle time
Where:
Cycle time=1ns=10^-9s
Hence:
CPI (Complier A)=1.1s/10^9×10^-9s
CPI (Complier A)=1.1
CPI (Complier B)=CPU time/Instruction×Cycle time
CPI (Complier B)=1.5s/1.2×10^9×10^-9s
CPI (Complier B)=1.25
Inconclusion the average CPI for each program given that the processor has a clock cycle time of 1 ns is : 1.1, 1.25.

The third assignment involves writing a Python program to compute the cost of carpeting a room. Your program should prompt the user for the width and length in feet of the room and the quality of carpet to be used. A choice between three grades of carpeting should be given. You should decide on the price per square foot of the three grades on carpet. Your program must include a function that accepts the length, width, and carpet quality as parameters and returns the cost of carpeting that room. After calling that function, your program should then output the carpeting cost.
Your program should include the pseudocode used for your design in the comments. Document the values you chose for the prices per square foot of the three grades of carpet in your comments as well.
You are to submit your Python program as a text file (.txt) file. In addition, you are also to submit a test plan in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.
Answer:
# price of the carpet per square foot for each quality.
carpet_prices=[1,2,4]
def cal_cost(width,height,choice):
return width*height*carpet_prices[choice-1]
width=int(input("Enter Width : "))
height=int(input("Enter Height : "))
print("---Select Carpet Quality---")
print("1. Standard Quality")
print("2. Primium Quality")
print("3. Premium Plus Quality")
choice=int(input("Enter your choice : "))
print(f"Carpeting cost = {cal_cost(width,height,choice)}")
Explanation:
The cal_cost function is used to return the cost of carpeting. The function accepts three arguments, width, height, and the choice of carpet quality.
The program gets the values of the width, height and choice, calls the cal_cost function, and prints out the string format of the total carpeting cost.

For which of the following tasks would a for-each loop be appropriate?
A. Reversing the order of the elements in an array.
B. Printing all the elements at even indices of an array.
C. Printing every element in an array.
D. Determining how many elements in an array of doubles are positive.
E. Determining whether an array of Strings is arranged in alphabetical order.
F. Printing every even number in an array of ints.
Answer:
The answer is "Option B, C, and F".
Explanation:
In the For-each loop, it is used for traversing items in a sequence is the control flow expression. It typically required a loop becomes referred to it as an enhanced loop for iterating its array as well as the collection elements. This loop is a version shortcut that skips the need for the hasNext() method to get iterator and the loop and over an iterator, and the incorrect choice can be determined as follows:
In choice A, it is wrong because it can't reverse the array element.In choice D, it is wrong because it can't determine the array of positive.In choice E, it is wrong because it can't determine an array of the sting in alphabetical order.Austin has a report due at school tomorrow, but has not started working on it yet. Now he is worried about getting a bad grade. So he searches the Internet for his topic and finds lots of information. He chooses a small, obscure site, copies text and images, and pastes them into his report. He's done before bedtime. But he receives an F on his report.
1. What could Sam have done differently on his report to avoid failing?
2. Is this incident an example of an unethical action or an illegal action?
Answer:
Explanation:
Question One
He could have read other sites with other points of view and summarized that. Most importantly he could have used footnotes that gave credit to every idea that he used.
He could have put the material down and begin to write. The words would have come out in his awkward style. He would still need to footnote the ideas. That is most important.
Question Two
It is both. Plagiarism is a serious crime if it involves many people being affected by what he wrote.
But it is totally unethical at any level. Trying to pass off something that isn't yours is totally unethical. It should never be done. It shames the subject which is shown to be unimportant and it shames the instructor (he knew enough to catch the plagiarism), and it shames the person getting caught.

You want to make access to files easier for your users. Currently, files are stored on several NTFS volumes such as the C:, D:, and E: drives. You want users to be able to access all files by specifying only the C: drive so they don't have to remember which drive letter to use. For example, if the accounting files are stored on the D: drive, users should be able to access them using C:\accounting. What can you do?
Answer:
volume mount points
Explanation:
The best thing to do would be to use volume mount points. This is a feature that allows you to mount/target (from a single partition) another folder or storage disk that is connected to the system. This will easily allow the user in this scenario to access the different files located in the D: and E: drive from the C:\ drive itself. Without having to go and find each file in their own separate physical drive on the computer.

Explanation:
In this assignment, you will implement an online banking system. Users can sign-up with the system, log in to the system, change their password, and delete their account. They can also update their bank account balance and transfer money to another user’s bank account.
You’ll implement functions related to File I/O and dictionaries. The first two functions require you to import files and create dictionaries. User information will be imported from the "users.txt" file and account information will be imported from the "bank.txt" file. Take a look at the content in the different files. The remaining functions require you to use or modify the two dictionaries created from the files.
Each function has been defined for you, but without the code. See the docstring in each function for instructions on what the function is supposed to do and how to write the code. It should be clear enough. In some cases, we have provided hints to help you get started.
def import_and_create_dictionary(filename):
'''
This function is used to create a bank dictionary. The given argument is the filename to load.
Every line in the file will look like
key: value
Key is a user's name and value is an amount to update the user's bank account with. The value should be a
number, however, it is possible that there is no value or that the value is an invalid number.
What you will do:
- Try to make a dictionary from the contents of the file.
- If the key doesn't exist, create a new key:value pair.
- If the key does exist, increment its value with the amount.
- You should also handle cases when the value is invalid. If so, ignore that line and don't update the dictionary.
- Finally, return the dictionary.
Note: All of the users in the bank file are in the user account file.

Explanation:
The python program is a banking application system that creates a list of user accounts and their login details from the bank.txt and user.txt file. The program also uses the information to log in and check for users already logged into their account with the "loggedin" global variable.
In this exercise we have to use the knowledge of programming in the python language, in this way we find that the code can be written as:
The code can be seen in the attached image.
To make it even simpler to visualize the code, we can rewrite it below as:
def import_and_create_dictionary(filename):
bank = {}
i = 1
with open(filename, "r") as file:
for line in file:
(name, amt) = line.rstrip('\n').split(":")
bank[i] = [name.strip(), amt]
i += 1
return bank
#create the list of user login details.
def import_and_create_accounts(filename):

(Apply) Students will write a function and loop to iterate until a condition is met LO: (Analyze) Students will identify edge cases from a problem statement. In this game of volleyball, two teams compete to be the first team to score 21 points. However, to win the game, a team must also lead by two points. For example, if team A is tied with team B (20-20) and then scores, they will only be ahead by one point (21-20). Then, if team B scores a point, the game will be tied again (21-21). Then, if either team can score two consecutive points, they will win. Write a program that reads data about volleyball matches from standard input and then determines the outcome of the game. If the input word is "A" it means that team A scored a point. If the input word is "B" it means that team B scored a point. If the input word is "end" it means that the game ended. Write a function that can be used in a loop as part of the condition. It should evaluate if either team is a winner. Call the function weHaveAWinner. In main, calculate the scores and announce the team that won or that the game was a draw. Display the game result in this format:
Team A won! (21-14)
Game ended as a draw. (21-21)
#include
using namespace std;
/*
* Determines the outcome of a volleyball game.
*/
int main() {
return 0;
}
Answer:
The program is as follows:
#include<iostream>
using namespace std;
void weHaveAWinner(int A, int B){
if(A-2>=B){
cout<<"Team A won! ("<<A<<"-"<<B<<")"; }
else if(B-2>=A){
cout<<"Team B won! ("<<A<<"-"<<B<<")";}
else if(B == A){
cout<<"Game ended as a draw. ("<<A<<"-"<<B<<")";}
else{
cout<<"Team A: "<<A<<" - Team B: "<<B;}
}
int main() {
int teamA = 0; int teamB = 0;
string score;
cout<<"Score: "; cin>>score;
while(score != "end"){
if(score == "A"){
teamA++;}
else if(score == "B"){
teamB++;}
cout<<"Score: "; cin>>score;
}
weHaveAWinner(teamA,teamB);
return 0;
}
Explanation:
This defines the weHaveAWinner function, which receives the scores of both teams as its parameters
void weHaveAWinner(int A, int B){
This checks if team A score at least 2 more than team B. If yes, it declares team A the winner
if(A-2>=B){
cout<<"Team A won! ("<<A<<"-"<<B<<")"; }
This checks if team B score at least 2 more than team A. If yes, it declares team B the winner
else if(B-2>=A){
cout<<"Team B won! ("<<A<<"-"<<B<<")";}
This checks for a draw
else if(B == A){
cout<<"Game ended as a draw. ("<<A<<"-"<<B<<")";}
This checks if both team are within 1 point of one another
else{
cout<<"Team A: "<<A<<" - Team B: "<<B;}
}
The main begins here
int main() {
This declares and initializes the score of both teams to 0
int teamA = 0; int teamB = 0;
This declares score as string
string score;
This prompts the user for score
cout<<"Score: "; cin>>score;
This loop is repeated until the user inputs "end" for score
while(score != "end"){
If score is A, then teamA' score is incremented by 1
if(score == "A"){
teamA++;}
If score is B, then teamB' score is incremented by 1
else if(score == "B"){
teamB++;}
This prompts the user for score
cout<<"Score: "; cin>>score;
}
This calls the weHaveAWinner function at the end of the loop
weHaveAWinner(teamA,teamB);

Write a program in your favorite language (e.g., C, Java, C , etc.) to convert max. 32 bit numbers from binary to decimal. The user should type in an unsigned binary number. The program should print the decimal equivalent. You should write a program from scratch that performs the conversion, please do not use built in functions. Please provide a screenshot of your program running on these values: 111011012 110000110011110101110101011101012 Please also include your source code together with your answers to assignment questions.
Answer:
In Python:
bin = int(input("Binary Number: "))
num = str(bin)
dec = 0
for i in range(len(num)):
dec = dec + int(num[i]) * 2**int(len(num)-i-1)
print("Decimal Equivalent: "+str(dec))
Explanation:
Note that the program assumes that the user input will be valid. So, error check was done in the program
This line gets the binary number from the user
bin = int(input("Binary Number: "))
This converts the inputted number to string
num = str(bin)
This initializes decimal number to 0
dec = 0
This iterates through the string number
for i in range(len(num)):
This converts the number to decimal
dec = dec + int(num[i]) * 2**int(len(num)-i-1)
This prints the result of the conversion
print("Decimal Equivalent: "+str(dec))

As you will solve more complex problems, you will find that searching for values in arrays becomes a crucial operation. In this part of the lab, you will input an array from the user, along with a value to search for. Your job is to write a C++ program that will look for the value, using the linear (sequential) search algorithm. In addition, you should show how many steps it took to find (or not find) the value, and indicate whether this was a best or worst case scenario (... remember the lecture). You may refer to the pseudo-code in the lecture, but remember that the details of the output and error conditions are not specified there. Also, note that in pseudo-code arrays are sometimes defined with indices 1 to N, whereas in C++ the indexes span from 0 to N-1.
The program will work as follows. First, you should ask the user to enter the size of the array, by outputting:
"Enter the size of the array: "
to the console. If the user enters an incorrect size, you should output the error message:
"ERROR: you entered an incorrect value for the array size!"
and exit the program. If the input is a valid size for the array, ask the user to enter the data, by outputting
"Enter the numbers in the array, separated by a space, and press enter: "
Let the user enter the numbers of the array and store them into a C++ array. Up to now, this should be exactly the same code as Lab#2. Next, ask the user a value v to search for in the array (called the "key"), by outputting:
"Enter a number to search for in the array: " to the screen, and read the key v.
Search for v by using the linear search algorithm. If your program finds the key, you should output:
"Found value v at index i, which took x checks. "
where i is the index of the array where v is found, and x is the number of search operations taken place.
If you doesn't find the key, then output: "
The value v was not found in the array!"
Then indicate whether you happened to run into a best or worst case scenario. In case you did, output: "
We ran into the best case scenario!" or "We ran into the worst case scenario!"
otherwise, don't output anything.
Answer:
#include<iostream>
using namespace std;
int main() {
cout<<"Enter The Size Of Array: ";
