**NEED HELP??!! Computer Science Questions!! KNOWING GIMP!!!!

1 answer:

8 0

1. If my memory serves me well, the answer is true. Free select tool is also called lasso and it’s used to free-hand selection. You can also combine free select tool segments with polygonal segments or other shapes.

2. I think this statement is definitely “False”. As I’ve mentioned before you can combine free selection with other selection features like polygonal by using anchors.

3. I’m not 100% sure, but I guess this one is true. As far as I remember, add to selection mode lets you to add new selection to any existing areas. So I think it’s possible to add selection to the existing one.

4. I think this one is also true. But it allows you just paint it, but it’s also kinda modification. Quick Mask allows you to isolate subject and paint selected object. It helps you not to brush subject accidentally. It’s a very useful tool as for me.

5. Yes, this statement is 100% true. But it could be gray for GIMP, because the mask is coded in gray tones, but I think that black is also gray tone. Color black or gray removes part of selection, and color white adds area to existing selection.

6. According to what I’ve mentioned before this one is also true, so there’s no need for additional explanation.

7. Another tool, similar to the Lasso/Free Select tool is the B) Scissors Tool. As there was mentioned intelligent scissors tool is almost the same as lasso but more user-friendly.

8. It’s false. You must click to the first point of your selection to finish the process or you will lose your selection.

9. I think this one is true. Paths tool includes two or more line segments connected by handle points. These points are kinda anchors I guess.

10. After making a selection using the Paths Tool, I must select the the D) Selection from Path button to turn my path into a selection. You can find it in path tool options.

11. Yes, it’s true, it allows you to make complex selections with curved or straight lines. Just drag one of the anchors to curve the line. Also you can create different geometrical figures with this tool.

12. Yes this is true. But there are much more cool blur filters than only Gaussian blur. Experiment on your own.

13. You can do all of the following given above. Every layer is kinda isolated image and you can modify it however you want.

14. I’m definitely sure that this statement is true. Just find layer drop down menu and follow the instructions given in this question. It’s simple.

What are the differences and similarities of computer virus and biological virus. Give 4 examples

Papessa [141]

Answer:

During recent months, we’ve witnessed an unexpected and distressing pandemic of a coronavirus disease. What I find especially distressing about it is how the worldwide adversity was caused by just a tiny thing — namely, a virus called SARS-CoV-2.

However, biological viruses have always been a potent threat to humanity, as historic pandemics have proved. No wonder viruses became an ideal weapon model in a totally different world — a world of programming. The first computer viruses were created as early as in the 1970s. Starting as pranks, they evolved to become a major threat to the stability of computer networks worldwide. And the more I think of viruses, both biological and digital, the more amazed I am by their similarities.

We don’t know what kind of challenges viruses of either type will cause in the future, but understanding how they infect, the symptoms they induce, how they spread, and the damage they can cause can help us fight both.

The Common Thread

Let’s start with the basics: What does a virus look like?

computer virus of 1999

The images in Figure 1 might look vastly different, but, essentially, they’re the same: a string of code. In the coronavirus, it’s the RNA genome in a shell; in Melissa, it’s computer code. In both cases, the code is an “instruction” for the virus to follow.

If you are writing an algorithm and you aren’t confident that you understand the problem, what can you do?

Zigmanuir [339]

Answer:

divide it into smaller pieces

Explanation:

Usually, the main reason a programmer does not understand a problem fully is that there is too much information. The best way to try and fully understand a problem is to divide it into smaller pieces. Start off by answering the question what is the expected output for an input. Then divide each individual issue within the problem. This will allow you as a programmer/developer to create an individual solution for each individual issue within the problem and then test to make sure that the input gives the correct output.

JAVA

marshall27 [118]

Answer:

Answer is in the provided screenshot!

Explanation:

Steps required to solve this problem:

1 - define what characters are "vowels" by assigning them to an array.

2 - create a variable to record the amount of vowels there are in the string.

3 - convert the input string into a character array and iterate through each character

4 - for each of the character of the string we go through, check if it matches any of the vowels

5 - return true if the vowel count is greater than 1

Alternative methods using the Java Stream API have also been wrote, please respond if you require them.

Write a java application that will determine the salary for each of several employees. The

nalin [4]

The program illustrates the use of repetitive operations.

The program in java is as follows, where comments are used to explain each line

import java.util.*;

public class Main{

public static void main(String [] args){

//This creates a scanner object

Scanner input = new Scanner(System.in);

//This declares employee number and hours, as integer

int empNum, hrs;

//This declares the rate and pay (salary) as double

double rate,pay;

//This gets input for employee number

empNum = input.nextInt();

//The following while operation is repeated until user inputs -1

while(empNum != - 1){

//This gets input for worked hours

hrs = input.nextInt();

//This gets input for work rate

rate = input.nextDouble();

//This calculates the pay (base salary)

pay = rate * hrs;

//If worked hours is more than 40

if(hrs >40){

//This calculates the additional pay

pay += 0.5 * pay;

}

//This prints the total salary

System.out.println("Salary: "+pay);

//This gets input for the employee number

empNum = input.nextInt();

}

}// The program ends here

At the end of the program, the program prints the employee's salary
