Answer:
C)
Explanation:
One principle that can improve the efficiency of I/O would be to move processing primitives into hardware. Primitives are a semantic value representing something else such as words or numbers within the programming language. By moving them into hardware they system is able to read them at a much faster speed making the I/O more efficient.
The answer is c. I just took it on apex n that’s what I got lol
Windows, icons, menus, and pointers does a graphical user interface (GUI) interact with a desktop or laptop computer.
- Windows, icons, menus, and pointers
<u>Explanation:</u>
Graphics user interface (gui) made a big resolution on desktop or laptop or tablet or workstation industries. In olden days till 1994 still, people were using the black and white computer where a desktop consists of keyboard and printer and monitors where display color white and black.
If we open a picture it will display only in black and white so games are in black and white mode. After windows 3.1 we have seen color picture and mouse interface is used. Since technology developed and interface in GUI is also developed improved in windows icon menu and mouse pointer.
As technology developed we going back to a dark mode such as black and white mode.

Answer:
Explanation:
The following is written in C++ and asks the user for inputs in both miles/gallon and dollars/gallon and then calculates the gas cost for the requested mileages using the input values
#include <iostream>
#include <iomanip>
using namespace std;
int main () {
// distance in miles
float distance1 = 20.0, distance2 = 75.0, distance3 = 500.0;
float miles_gallon, dollars_gallon;
cout << "Enter cars miles/gallon: "; cin >> miles_gallon;
cout << "Enter cars dollars/gallon: "; cin >> dollars_gallon;
cout << "the gas cost for " << distance1 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance1 / miles_gallon << "$\n";
cout << "the gas cost for " << distance2 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance2 / miles_gallon << "$\n";
cout << "the gas cost for " << distance3 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance3 / miles_gallon << "$\n";
return 0;
}
