The answer that fits the blank is XOR or Exclusive OR. Exclusive OR is a logical operation wherein it demonstrates the logic presented by "either/or". This means that if the output given is true, either of the inputs, but never both, should also be true.

A datagram network allows routers to drop packets whenever they need to. The probability of a router discarding a packetis p. Co
tresset_1 [31]

Answer:

a.) k² - 3k + 3

b.) 1/(1 - k)²

c.) k^{2}  - 3k + 3 * \frac{1}{(1 - k)^{2} }\\\\= \frac{k^{2} - 3k + 3 }{(1-k)^{2} }

Explanation:

a.) A packet can make 1,2 or 3 hops

probability of 1 hop = k  ...(1)

probability of 2 hops = k(1-k)  ...(2)

probability of 3 hops = (1-k)²...(3)

Average number of probabilities = (1 x prob. of 1 hop) + (2 x prob. of 2 hops) + (3 x prob. of 3 hops)

                                                       = (1 × k) + (2 × k × (1 - k)) + (3 × (1-k)²)

                                                       = k + 2k - 2k² + 3(1 + k² - 2k)

∴mean number of hops                = k² - 3k + 3

b.) from (a) above, the mean number of hops when transmitting a packet is k² - 3k + 3

if k = 0 then number of hops is 3

if k = 1 then number of hops is (1 - 3 + 3) = 1

multiple transmissions can be needed if K is between 0 and 1

The probability of successful transmissions through the entire path is (1 - k)²

for one transmission, the probility of success is (1 - k)²

for two transmissions, the probility of success is 2(1 - k)²(1 - (1-k)²)

for three transmissions, the probility of success is 3(1 - k)²(1 - (1-k)²)² and so on

∴ for transmitting a single packet, it makes:

     ∞                             n-1

T = ∑ n(1 - k)²(1 - (1 - k)²)

    n-1

   = 1/(1 - k)²

c.) Mean number of required packet = ( mean number of hops when transmitting a packet × mean number of transmissions by a packet)

from (a) above, mean number of hops when transmitting a packet =  k² - 3k + 3

from (b) above, mean number of transmissions by a packet = 1/(1 - k)²

substituting: mean number of required packet =  k^{2}  - 3k + 3 * \frac{1}{(1 - k)^{2} }\\\\= \frac{k^{2} - 3k + 3 }{(1-k)^{2} }

How do Hlookup and Vlookup differ?
german

HLOOKUP performs the same function as VLOOKUP, but looks up data that has been formatted by rows. HLOOKUP searches for a value in the top row of a table, and then returns a value in the same column from a row you specify in the table or array

Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the ra
Kazeer [188]

Answer:

See explaination

Explanation:

#include <iostream>

using namespace std;

class Circle{

// private member variable named radius

private:

double radius;

// get function for radius

public:

double getRadius(){

return radius;

}

// set function for radius

void setRadius(double rad){

radius=rad;

}

// returning area = 3.14159 * radius * radius

double getArea(){

return (3.14159 * radius * radius);

}

};

// Sample run

int main()

{

// Declaring object of Circle

Circle myCircle;

myCircle.setRadius(5);

// printing radius of circle

cout<<"Radius of circle is: "<<(myCircle.getRadius())<<endl;

// printing area of circle

cout<<"Area of circle is: "<<(myCircle.getArea())<<endl;

return 0;

}
