Answer:
1. internet connection is not enabled on the computer.
2. The DHCP server in the company is not enabled as well.
Explanation:
For a user to access the internet, the computer must have a public IP address that is either assigned to it by a service provider or dynamically from the DHCP server in the computer. In the case of the former, the user just needs to enable the internet connection to obtain the unique IP address.
If the DHCP server or the internet connection is not enabled, the user would not have access to the internet.
Answer:
C++ programming language (code) was used or applied in prompting a user to enter he number of series components in a system and the MTBFs for each component and then calculates the overall MTBF for the system using a FOR or a WHILE structure (loop).
Explanation:
Solution
THE CODE
#include<iostream>
#include<cmath>
using namespace std;
int main()
{
int key;
// do while loop to run the program up to user wants to quit "to quit enter any number except 1 "
do
{
int n,i=0,mtbf[100]; //declaring array to store the mtbf values of the n components
float result=0,result1;
cout<<"\n Enter number of components";
cin>>n;
while(i<n) // reading mtbf values into the array
{
cout<<"\n Enter MTBF(Mean time between failure)==>";
cin>>mtbf[i];
i++;
}
i=0;
while(i<n) //in this while loop first i calculate the denominator part i.e (1/mtbf[i])+(1/mtbf[i])...
{
result+=(1.0/mtbf[i]);
i++;
}
result1=1/result; //this value calculate the total MTBF of the system
cout<<"\n The MTBF of SYSTEM is\t"<<result1;
cout<<"\n Another system to check? enter 1 for yes";
cin>>key;
}while(key==1);
}
