Answer:
Here is c program:
#include<stdio.h>
#include<conio.h>
void main()
{
//Variable declaration
//array to hold 6 values you can change this as needed
float nums[6];
//integer i is for loop variable
int i;
//to hold maximum value
float max=0.0;
//clear screen
clrscr();
//iterate 6 times you can change as per your need
for(i=0;i<6;i++)
{
printf("Enter a number:");
scanf("%f",&nums[i]);
//check if entered value is greater than previous value
//if it is greater then assign it
if(nums[i]>max)
max = nums[i];
}
//print the value
printf("The largest number entered was %f",max);
getch();
}
Explanation:
Answer: A. Multicast
Explanation:
Here we are given a situation where it is necessary for the device to stream media to all the PCs connected across the LAN. But as the they are unable to stream the media then it is a problem in the multicast TCP/Ip technology.
Multicasting enables to transfer information or messages from one to many or many to many. Here as a single device is responsible for streaming the content to other PCs across the LAN, therefore it is necessary that multicast has been properly implemented.
Option B is incorrect as it is not a scenario of broadcast as in broadcasting all the receivers must get the streaming however here if a PC does not want to receive the media stream it cannot receive for which multicasting is required.
Option C is incorrect as here we are not talking of one to one communication.
Option D is incorrect as here we cannot have more than one route to send the media content except the LAN.
