Suppose Host A wants to send a large file to Host B. The path from Host A to Host B has three links, of rates R1 = 500 kbps, R2

= 2 Mbps, and R3 = 1 Mbps. a. Assuming no other traffic in the network, what is the throughput for the file transfer? b. Suppose the file is 4 million bytes. Dividing the file size by the throughput, roughly how long will it take to transfer the file to Host B? c. Repeat (a) and (b), but now with R2 reduced to 100 kbps

Answer & Explanation:

a)

Throughput means the speed of the slowest link which is bottleneck for the network.

In the above case R1 = 500kbps is the throughput for file transfer.

b) Give file size = 4 million bytes =4 * 1,000,000 * 8 bits = 32,000,000 bits =

Time taken to transfer the file = filesize/throughput = 32,000,000/500,000 = 64 seconds

When R2 reduced to 100kbps

a)  

In this case R2 = 100kbps is the throughput for file transfer.

b) Give file size = 4 million bytes =4 * 1,000,000 * 8 bits = 32,000,000 bits =

Time taken to transfer the file = filesize/throughput = 32,000,000/100,000 = 320 seconds

Write a do-while loop that continues to prompt a user to enter a number less than 100, until the entered number is actually less
Ad libitum [116K]

Answer:

#include<iostream>//library inclusion

using namespace std;

int main()

{

int userInput;

do//start of do while loop

{

 cout << "Enter a number less than a 100" << endl;

 cin >> userInput;

 if (userInput < 100) //condition

 {

  cout << "YOu entered less than a hundred: " << userInput << endl;

 }

 else

 {

  cout << "your number is greater than 100" << endl;

 }

} while (userInput > 100);//condition for do while

return 0;//termination of int main

}

Explanation:

The program has been commented for you. The do-while loop enters the first loop regardless of the condition. Then after the first iteration, it checks for the condition. If the condition is being met, it will iterate through, again. Otherwise it will break out of the loop and land on the "return 0;" line. Which also happens to be the termination of the program in this case. The if-else condition is used for the user to see when prompted.

A*=++a/6+b++ 3 if a=3,b=4​
Vinil7 [7]

Answer:

a=22.5

Explanation:

Given

a*=++a/6+b++3

Required

The result when a=3 and b=4

Analyzing the given instruction

a*=(++a)/(6)+(b++3)

Single out and solve the expressions in bracket

(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.

So: in this case: ++a = a

b++3 = b + 3

The operator, as used in that statement is the same as: b + 3.

So:

a*=(++a)/(6)+(b++3)

a*=(a)/(6)+(b+3)

a*=(3)/(6)+(4+3)

a*=0.5+7

a*=7.5

The above expression is calculated as:

a=a*7.5

So:

a=3*7.5

a=22.5
