physical layer is used to transmit media,signal and binary information

datalink layer is used for physical addressing MAC and LLC

network layer is used for path determination and ip

transport layer is for end to end communication and reliability

session layer is for interhost communication

Implementations <br> in c++ programming when finding lcm and gcd in c++​
vazorg [7]

Answer:

#include<iostream>

using namespace std;

int lcm(int m, int n) {

  int a;

  a = (m > n) ? m: n;

  while (true) {

     if (a % m == 0 && a % n == 0)

        return a;

        ++a;

  }

}

int gcd(int m, int n) {

  int r = 0, a, b;

  a = (m > n) ? m : n;

  b = (m < n) ? m : n;

  r = b;

  while (a % b != 0) {

     r = a % b;

     a = b;

     b = r;

  }

  return r;

}

int main(int argc, char **argv) {

  cout << "Enter the two numbers: ";

  int m, n;

  cin >> m >> n;

  cout << "The LCM of two numbers is: " << lcm(m, n) << endl;

  cout << "The GCD of two numbers is: " << gcd(m, n) << endl;  

  return 0;

}

Namespaces are guaranteed to be unique.<br><br> True<br><br> False
kupik [55]

Answer:

True

Explanation:

Some collection of classes or library functions grouped as one name space. A class which belongs to one namespace is different from the class which belongs to another namespace. we can identify a class uniquely with it's namespace .

for ex:

in c#.net

using system;

System.IO;

here System is the namespace which contains class IO

namespace contains any number of classes . In one namespace we can't define two classes with same Name. We can define two classes with same name in different namespaces

Answer the following questions:
victus00 [196]

Answer:

The answer to the following questions can be given as:

Question: 1

value of foo is = 1020

Question: 2

Output of the code is = false

Question: 3

function add(a, b)

{

 return a && b ? a + b : function (c) { return a + c; };

}

var a=add(2,5);

var x=add(2)(5);

print(a);

print(x);

output:  

7

7

Question: 4

"goh angasal a m'i"

Question: 5

In this we check that if in the window a foo function exists. otherwise we set windows.foo to bar.

Question: 6

first alert shows the value "Hello World";

second alert shows value ReferenceError, In this bar not defined.

Question: 7

The value of foo.length is  2

Question: 8

The value of foo.x is undefined

Question: 9

Function print = "one", "three", "two" .

Question :10

It is difficult to define because doSomethingElse() function is not defined.

Explanation:

In question 1 the value of the foo variable is 1020 because we perform the string concat operation.

In question 2 Output of the code is false because float value keeps in binary and when we convert 0.1 or 0.2 to binary so it is not the same.

In question 3 the output of both functions is 7.

In question 4 the output is goh angasal a m'i because In this code we use the reverse() function, split() function and join() function. Reverse function reverses the value. split function splits the value and join function join all the value of the string in a line.

In question 5 we check the value.

In question 6, the first output is Hello World and second is ReferenceError.

In question 7, the value of foo.length is 2 because this foo array we insert only 2 values.

In question 8, the value of foo.x is undefined because in the variable we reset the value of foo all together, so foo.x value is undefined.

In the question 9 function print "one",  

"three",  

"two" because In the function first, we print the message that is "one" then we define a function in this function we print the value  

"two" but before creating object we call the "three" so the print value is "one",  

"three",  

"two".

In question 10 function, the output of this function is undefined.
