<span>a. DA Given the question and available options, this looks like a question about Ethernet frames. So let's look at the options and see what makes sense. a. DA * DA - Destination address. And the question pretty much defines what it is. So this is the correct choice. b. SA * SA - Source address. This is the physical address that the frame was sent from. And since the question is mentioned who the frame is intended for, this is obviously the wrong choice. c. SFD * SFD - Start Frame Delimiter. This is a special CONSTANT sequence of bits that terminates the preamble. It's purpose is to indicate the start of the frame payload. Since it's a constant value, it does not indicate in any way where the frame is intended to go. So this is a bad choice. d. Preamble * Preamble - is a pattern of alternating 0 and 1 bits intended to synchronize receivers so that the rest of the frame is interpreted correctly. This too is a constant value and as such can't indicate the destination of the frame, so it's a bad choice.</span>

A news website uses 32-bit integers to count the number of times an article has been viewed. The website is becoming more popula
Irina-Kira [14]

Answer:

2^32 times as many values can be represented

Explanation:

32-bit. This means that the number is represented by 32 separate one’s and zero’s. 32 bits of 2 possible states = 2^32=4,294,967,296 possible values.

Integer meaning that only whole multiples of one are accepted.

Signed meaning that negative values are accepted. This halves the number of possible positive values (roughly), so the largest number you can represent is 2^31–1=2,147,483,647, but instead of 0, the smallest number you can represent is -2,147,483,648. An unsigned 32-bit integer, by contrast, can represent anything from 0 to 4,294,967,295.

Create a structure representing a student. The member variables should include student name, student ID, and four test grades fo
Neporo4naja [7]

Answer:

Output:

Name: Brainly

ID:0001

Write the 4 tests grades of the student separated by space :10 9 8 10

Brainly

0001

10 9 8 10

Average :9.66667

'1' to continue '0' to exit :

Explanation:

#include<iostream>

#include<string>

using namespace std;

//variables declaration

struct Student {

  string id; //string declaration ID

  string name; // string declaration name

  int grades[4]; //array of 4 because it is 4 grades

};

//definition of the function get information

void inputData(Student &s){

 

   

   cout << "Name:" ;

   getline(cin,s.name);

   cout << "ID:";

   cin >> s.id;

   cout << "Write the 4 tests grades of the student separated by space :";

   for (int i = 0; i<4; i++)

       cin >> s.grades[i];

}

//definition of the function of average

double inputAvg(Student s){

   double summation;

   int temporary;

   double average;

   for (int i = 0; i<4; i++){  

      for (int j = i; j<4; j++){

         if (s.grades[j] > s.grades[i]){

             temporary = s.grades[i];

             s.grades[i] = s.grades[j];

             s.grades[j] = temporary;

         }

      }

    }

    summation = 0;

    for (int i = 0; i<3; i++){

        summation = summation + s.grades[i];  

    }

    average = summation/3;

    return average;

}

void disp(Student *s){

   cout << s->name << endl;

   cout << s->id << endl;

   for (int i = 0; i<4; i++)

       cout << s->grades[i] << " ";

   cout << endl;

   cout << "Average :" << inputAvg(*s) << endl;

   

}

int main(){

  Student st;

  int ch;

  while(true){

      inputData(st);

      disp(&st);

      cout << " '1' to continue '0' to exit :";

      cin >> ch;

      if (ch == 0)

         break;      

  }

  return 0;

}
