Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
Answer:
The program to this question can be describes as follows:
Program:
#include <iostream> //defining header file
using namespace std;
int main() //defining main method
{
float user_num ;//defining float variable
cout<<"Enter any number: "; //message
cin>>user_num; //input value from the user
while (user_num >= 1) //defining loop to calculate value
{
user_num =user_num/ 2; //diving the value
cout<<user_num<<endl; //print value
}
return 0;
}
Output:
Enter any number: 20
10
5
2.5
1.25
0.625
Explanation:
In the above program, a float variable user_num is declared in which we store input value from the user end, in the next step, a while loop is declared, which calculates, the given value.
- In the loop a condition is defined, that user_num value is greater than equal to 1, inside the loop it will divide the value of the user_num and store in this variable.
- In this print, the method is used, which prints its variable values.

Answer:
Broadcast message
Explanation:
The network models like OSI and TCP/IP suites have standard layers and protocols that governs the communication of end devices in a network.
The TCP/IP suite model has four layers which are application, transport, internet and network access layers. The network access does the work of both the data-link and physical layer of the OSI model.
When the packet is encapsulated in a data-link header and trailer, and needs to be sent to another unknown host, a broadcast message is sent to all the computers in the network to retrieve the remote host address for a unicast transmission to take place.
A) tested again because you would need to see if that worked
