Functions of personal firewall, hardware firewall, antivirus
Personal firewall:
- It is a network security tool and its function is to find and protect computers and all its information from unauthorized intrusions.
- It regularly monitors all the communication happens to and from the computer.
- If any intrusions occur, then the personal firewall informs the user by giving a message.
- Example: If the user downloads any software or any file from the Internet, and if that file contains virus; then the firewall instructs the user that the file contains virus and warns to discard that file.
- Example of personal firewall is Comodo firewall.
Hardware firewall:
- It is a device and its function is to stop the network interruptions before they try to affect the computers.
- Routers also acts as a hardware firewall.
- Hardware firewall uses packet filtering method in order to examine the header of the packet that contains source and destination.
- Example of hardware firewall is Cisco SA 500...

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
// Method that calculates the square root of double variables
public static double myRoot(double number) {
double root;
root number/2;
double root_old;
do {
root old root;
root (root_old+number/root_old)/2;
while (Math.abs (root_old-root)>1.0E-6);
return root;
}
}
