Answer:
<u>The total time elapsed from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B is </u><u>25.11 ms</u>
Explanation:
Host A first converts the analog signal to a digital 64kbps stream and then groups it into 56-byte packets. The time taken for this can be calculated as:
time taken 1=
= (56 x 8) bits / 64 x 10³ bits/s
= 7 x 10⁻³s
time taken 1= 7 ms
The transmission rate of the packet from Host A to Host B is 4 Mbps. The time taken to transfer the packets can be calculated as:
time taken 2= (56 x 8) bits / 4 x 10⁶ bits/s
= 1.12 x 10⁻⁴ s
time taken 2= 112 μs
The propagation delay is 18 ms.
To calculate the total time elapsed, we need to add up all the time taken at each individual stage.
<u /><u> = Time taken 1 + Time taken 2 + Propagation Delay</u>
= 7 ms + 112 μs + 18 ms
= 0.025112 s
= 25.11 ms
Answer:
I am writing a C program:
#include <stdio.h> //to use input output functions
void printIt(double annual_in){ //function printIt
if(annual_in >90000) //check if the income is greater than 90000
printf("Congratulations. Doing great!"); //print this message if income value is greater than 90000
else //if annual income is less than 90000
printf("You WILL make $50,000, if you keep going"); } //print this message if income value is less than 90000
int main() //start of main() funciton body
{ double income; //declares a double type variable income to hold annual income value
printf("Enter annual income: "); //prompts user to enter annual income
scanf("%lf",&income); //reads income value from user
printIt(income); } // calls printIt method by passing input income to that function
Explanation:
The program is well explained in the comments mentioned with each statement of the program. The flowchart is attached.
First flowchart flow1 has a separate main program flowchart which reads the income and calls printIt function. A second flowchart is of prinIt() method that checks the input income passed by main function and displays the corresponding messages and return.
The second flowchart flow2 is the simple flowchart that simply gives functional description of the C program as flowchart is not where giving function definitions is important. Instead of defining the function printIt separately for this C program, a high-level representation of functional aspects of this program is described in second flowchart while not getting into implementation details.
