What are the differences between a trap (aka software interrupt) and an interrupt (hardware interrupt)? What is the use of each

Marta_Voda [28]

Answer:

Trap is a software interrupt that occurs when there is a system call, while hardware interrupt occurs when a hardware component needs urgent attention.

Explanation:

Interrupt is an input signal that disrupt the activities of a computer system, giving immediate attention to a hardware or software request.

In trap interrupt, the system activities are stop for a routine kernel mode operation, since it has a higher priority than the user mode. At the end of the interrupt, it switches control to the user mode.

The hardware interrupt is a signal from hardware devices like the input/output devices, storage and even peripheral devices that draws an immediate attention of the processor, stopping and saving other activities and executing the event with an interrupt handler.

Write a recursive function that takes a non-negative integer as an argument and displays the same number in reverse order (i.e.

avanturin [10]

Answer:

Following are the program in C++ language

#include<iostream> // header file

using namespace std; // namespace std

int reverse(int n1); // function prototype

int main() // main function()

{

int num; // Variable declaration

cout << "Enter the number" << endl;

cin >> num; // Read the number bu the user

cout<<"After Reverse the digit:\n";

int res= reverse(num); // calling function reverse

cout<<res; // display

}

int reverse(int n1) // function definition of reverse

{

if (n1<10) // checking the base condition

{

return n1;

}

else

{

cout << n1 % 10; // Printed the last digit

return reverse(n1/10); // calling itsself

}

Output:

Enter the number:

76538

After Reverse the digit:

83567

Explanation:

Following are the description of the program

In the main function read the number by user in the "num" variable of int type.

Calling the reverse and pass that "num" variable into it.

After calling the control moves to the body of the reverse function.In this function we check the two condition

1 base condition

if (n1<10) // checking the base condition

{

return n1;

}

2 General condition

else

{

cout << n1 % 10; // Printed the last digit

return reverse(n1/10); // calling itsself

}

Finally return the reverse number and display them into the main function.

The fast movement of briefly flashed images in an animated motion picture produces what effect? subliminal messaging convergence

REY [17]

Answer:

The answer is Stroboscopic movement

Explanation:

Stroboscopic movement occurs when we do not see a motion continuously but in discrete shots. It is an effect in which we see an object at one place and after another instant the object seems to have shifted it's position.

Auto kinetic effect is an effect in which a stationary point of light appears to move.It occurs as our brains can perceive motion relative to some other object and cannot observe ,motion along a featureless terrain or environment.

Phi effect causes an observer to perceive motion in stationary objects.

You try to enter your name into a cell that accepts a numeric value. What error would you receive? A. #NAME B. #VALUE C. #REF D.

UNO [17]

Answer:

<h2>Option B: #VALUE</h2>

is the correct answer.

Explanation:

<h3>Reasons of #VALUE error:</h3>

When cells are not given the expected type of value.
If cells are left blank unnoticeable or for giving a null value.
For entering dates and other numerical data in text form.

<h3>Correcting and fixing #VALUE error:</h3>

This type of error can only be fixed by finding the cell in which there is wrong data entered and correct it.

Fixing the #VALUE error is tricky as some functions automatically ignore the data that is invalid.

<h3>EXAMPLE:</h3>

Suppose a cell contains the value as cost of the object and in order to make it 0, NA is inserted into the cell.

While making total of all the costs, that particular cell might cause #VALUE error.
Following image attach will help you clear the concept.

I hope it will help you!
