Instructions: Select the correct text in the passage.Mr. Crowell has been teaching in a school for years with the help of traditional teaching methods. Recently, the school authorities have recommended the use of computer programs and applications to facilitate a better learning experience for their students. Mr. Crowell wants to make the classroom learning stimulating and interesting. He will have to use a few of the several computer applications available to him. These applications include email, multimedia presentations, spreadsheets, word processing software, videos, and simulations.

Options:

-email
-multimedia presentations
-spreadsheets
-word processing software
-videos
-simulations

Answers

Since Mr. Crowell wants to make his classroom more stimulating through the implementation of computer applications, he should consider using multimedia presentations, videos, and simulations to supplement his current teaching methods.

Since his main goal is to create a better learning experience, email, spreadsheets, and word processing software would not be good choices for him to use in his class since his students cannot interact with these applications.

These applications include email, multimedia presentations, spreadsheets, word processing software, videos, and simulations.

Why does a CPU need Thermal Grease?

Answers

The CPU generates a lot of heat while doing its job, and if the CPU can't get rid of
the heat, that's very bad for the CPU.  (Scientists say the CPU 'fails'.  Engineers say
the CPU 'dies'.  Users say the CPU 'burns up'.)

If you look at the CPU in your computer, you'll see that it's mounted on a big black
piece of metal with lots of fins and grooves in it, called a "heat sink".  There may
also be a little fan blowing air past the heat sink, to help take heat away from it. 
The thermal grease carries heat from the CPU to the heat sink faster than if they
were just bolted together with nothing in between them.

Answer:

Binary Scope Resolution Operator

Explanation:

The :: (scope resolution) operator is used to get hidden names due to variable scopes so that you can still use them. The scope resolution operator can be used as both unary and binary. Fortunately, in this context we're not dealing with hidden contents; thus the Binary applies better than the Unary.

What is the output of the following program?#include using namespace std;void doSomething(∫);int main(){int x = 2;cout << x << endl;doSomething(x);cout << x << endl;return 0;}void doSomething(int &num){num = 0;cout << num << endl;}

Answers

Answer:

The outputs of the code is

2

0

2

Explanation:

First, I'll arrange the code line by line. While arranging the code, I'll make some corrections

#include <iostream>

using namespace std;

void doSomething();

int main(){

int x = 2;

cout << x <<endl;

doSomething(x);

cout << x << endl;

return 0;

}

void doSomething(int &num)

{

num = 0;

cout << num << endl;

}

At line 6, the value of x which is 2 is printed and the line is terminated to prevent printing of value on the same line. So, the next print statement will start on the next line.

At line 7, the function doSomething () is called.

This statement will execute the instructions in the doSomething () function and print value 0. This line is also terminated.

At line 8, the value of x is printed which is also 2

Answers

Answer:

The correct answer is Screen Resolution.

Explanation:

Basically, Screen Resolution refers to the text and the displayed images on your desktop so we can not relate this to designing a website. The most common screen resolution is 1024×768 in which 1024 pixels is the width and 768 pixels is height.

  • There are some base names for screen resolutions such as - for TV's (HDTV and UHD) and for computer monitors (XGA and WQXGA).
  • Purpose, Audience and Theme they all are used for designing a website.
