The answer is firewall. It is a network security device that observes inbound and outbound network traffic and chooses whether to allow or block specific traffic based on a well-defined set of security rules. Firewalls have been a first line of protection in network security for over 25 years. The firewall present a barrier between measured and secured internal networks that can be trusted and untrusted outside networks, for example the Internet. A firewall can be software, hardware, or even both.
Answer
System restore
Explanation
System restore is a recovery feature that helps restore your system to the previous condition or point. Most computers have system restore disks which are an advantage to the users especially when the computer clashes.These disks are very effective when it comes to restoring the system to its initial state.
Answer:
// here is code in c++.
// include header
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables to read input
int userNum,x;
cout<<"enter the value of userNum and x :";
// read the input from user
cin>>userNum>>x;
// divide the userNum with x 4 times
for(int a=0;a<4;a++)
{
userNum=userNum/x;
cout<<userNum<<" ";
}
cout<<endl;
return 0;
}
Explanation:
Declare two variables "userNum" and "x". Read the value of these. Run a for loop 4 time and divide the "userNum" with "x" and print the value of "userNum".
<u>Output:</u>
enter the value of userNum and x :2000 2
1000 500 250 125
Answer:
c-Either A or B
Explanation:
The non-inverting amplifier usually has the input voltage connected to the non-inverting input while the inverting input is connected to the output.
Both the unit gain amplifier and the voltage follower have an input voltage connected to the non-inverting input, and the inverting input connected to the output, so both are special cases of the non-inverting amplifier.
The correct answer is
c-Either A or B
