What is a Firewall?

     A firewall is a computer network security system.

     Which will act on and off external access (e.g. from the Internet) access to internal networks (e.g. internal networks or personal computers)

     You might say that a firewall is like a computer's door guard. Which access from outside will have to pass through the firewall to check before being allowed to access the internal network or not.

     A firewall will have rules to enforce specific networks, which means that "If the access is valid as required by the firewall, then the network can be accessed.

      If it doesn't match, it won't be accessible" (also known as Default deny).
