Computer firewall is an OS based software designed to control the access to unauthorized content on a network or a computer system. It works with predefined set of rules, according to which it decides whether to block or allow access.
Windows firewall is the firewall application used by many windows users. It acts quickly to the attacking Trojans and blocks the access to those networks. Access to the blocked networks is possible only when the setting of the application is changed.

The growth of the internet has brought in to the introduction of many firewall applications, each one having different features.
Windows firewall is an application offered for free with the purchase of Windows OS.
Since the function of the firewall is based on the set of rules, it can often become worthless, if not configured properly. Optimized analysis has to be done on a computer followed by changes in the settings for complete protection.
