Answer: c. Depending on context the same sequence of bits may represent different types of information.

Explanation:

The options for the question are:

A. Computing devices use patterns of bits to represent complex information

B. Abstraction helps represent complex information by surfacing complexity that might otherwise be hidden

C. Depending on context the same sequence of bits may represent different types of information

D. Common abstractions that are represented by computing devices include numbers, characters, and color.

The following are true of how computers represent complex information:

• Computing devices use patterns of bits to represent complex information

• helps represent complex information by surfacing complexity that might otherwise be hidden

• Common abstractions that are represented by computing devices include numbers, characters, and color.

Therefore, the option that is not true of how computers represent complex information is that "depending on context the same sequence of bits may represent different types of information".

Write a method called makeStars. The method receives an int parameter that is guaranteed not to be negative. The method returns

serious [3.7K]

Answer:

// import the Scanner class

// to allow the program receive user input

import java.util.Scanner;

// The class Solution is defined

public class Solution{

// main method to begin program execution

public static void main(String[] args) {

// scanner object scan is declared

Scanner scan = new Scanner(System.in);

// Prompt the user to enter a number

System.out.println("Enter the number of stars you want: ");

// user input is assigned to numOfStar

int numOfStar = scan.nextInt();

// call the makeStars method

makeStars(numOfStar);

}

// makeStars method print stars using recursion

// the method call itself till starNum == 0

public static void makeStars(int starNum){

if (starNum != 0){

System.out.print("*");

makeStars(starNum -1);

}

Explanation:

The code is well comment and solve the problem using recursion.

To gain experience of using and combing different sorting algorithms: election sort, insertion sort, merge sort, and quick sort.

ch4aika [34]

Answer:

Motivation? The search problem.

Sorting algorithms: insertion sort, shellsort, heapsort, mergesort, quicksort, bubblesort

At the very least, "general purpose" sorting algorithms require O(n log n) comparisons

Suppose your company has decided that it needs to make certain busy servers faster. Processes in the workload spend 60% of their

vekshin1

Answer:

CPU need 50% much faster

disk need 100% much faster

Explanation:

given data

workload spend time CPU = 60%

workload spend time I/O = 40%

achieve overall system speedup = 25%

to find out

How much faster does CPU need and How much faster does the disk need

solution

we apply here Amdahl’s law for the overall speed of a computer that is express as

S = $\frac{1}{(1-f)+ \frac{f}{k} }$ .............................1

here f is fraction of work i.e 0.6 and S is overall speed i.e 100% + 25% = 125 % and k is speed up of component

so put all value in equation 1 we get

S = $\frac{1}{(1-f)+ \frac{f}{k} }$

1.25 = $\frac{1}{(1-0.6)+ \frac{0.6}{k} }$

solve we get

k = 1.5

so we can say CPU need 50% much faster

and

when f = 0.4 and S = 125 %

put the value in equation 1

S = $\frac{1}{(1-f)+ \frac{f}{k} }$

1.25 = $\frac{1}{(1-0.4)+ \frac{0.4}{k} }$

solve we get

k = 2

so here disk need 100% much faster

1. Discuss why it is so important for all application builders to always check data received from unknown sources, such as Web a

Ivan

Answer:

1. It is so important for all application builders to always check data received from unknown sources before using that data. This is because of the Security related reasons and vulnerabilities .For example the data received might contain harmful hidden viruses. Web applications are accessed by internet and these are the most vulnerable to attacks by hacker or intruders using harmful data containing malware. This can cause security breaches due to the security flaws or bugs in Web applications. So to overcome such security risks which can cause damage in the Web applications, data from unknown sources should be checked.

Explanation:

2. When the Website is being used and running, there is a room for possible glitches or other bugs and issues. To understand, handle and address issues successfully, the website operators carefully and consistently patch and configure their systems. The administrators collect the user data which enables them to have enough data in order to make the requisite alterations or improvements in the website. This also helps to improve the website performance. The patching and configuring of systems fix problems in the website which reduces the risk of website damage and the website works smoothly this way. Moreover it identifies vulnerabilities, solve configuration issues and upgrades in website features provide additional capabilities to the website.
