<span>Computers don't need system software. System software is used to automate many tasks so the user can achieve more. Actually, one of the ideas of computer programming is to avoid needless repetition. The system software will prepare the computer for the user.</span>
Answer:
Windows\System32\drivers folder.
Explanation:
Eric operates on such a computer which has some failure on system's driver. Although the specific system may not be operational, he will locate the system driver title. Inappropriately he has no Connectivity to the internet.
Windows\System32\drivers directory could move to him to show the file of the system driver. Thus, the following answer is correct according to the given scenario.
Answer:
#include<bits/stdc++.h>
using namespace std;
int sumOfinteger(int );
// Returns sum of all digits in numbers from 1 to n
int sumOfintegersFrom1ToN(int n) {
int result = 0; // initialize result
// One by one compute sum of digits in every number from
// 1 to n
for (int x = 1; x <= n; x++)
result += sumOfinteger(x);
return result;
}
// A utility function to compute sum of digits in a
// given number x
int sumOfinteger(int x) {
int sum = 0;
while (x != 0) {
sum += x %10;
x = x /10; }
return sum; }
// Driver Program
int main() {
int n ;
cout<<"enter a number between 1 and n : ";
cin>>n;
cout << "Sum of digits in numbers from 1 to " << n << " is " << sumOfDigitsFrom1ToN(n);
return 0; }
Answer:
The ping command.
Explanation:
In a network, workstations known as clients, users or nodes are the devices where data is needed or sents from. A server on the other hand, is a device in the network, configured to render a particular service like database, domain name service, web service etc.
When a link from a workstation to a server is down, the workstation looses connection the server. To confirm the connectivity of the link, "ping" the server ip address from the workstation using the command "ping 'server ip address'". This sends echo packets to the server, which is echoed back if there is connectivity.
