       Most of us have heard of the word firewall at some point. There
       are many misconceptions about firewall which we will clear
       today. If you are running any of the modern and popular
       operating systems, it is very likely that you have a firewall
       enabled.
       What Is a Firewall?
       First of all, in a firewall, there are no flames or actual wall
       involved which is obvious.
       A firewall is basically a shield that is meant to protect your
       Computer, Smartphone from various malware present on the
       Internet.
       Every time you browse a web page, a series of requests are sent
       by your browser to the respective web server in the form of data
       packets. The role of a firewall is to keep a close eye on these
       data packets and determine if they are safe or not.
       The firewall finds the tampered data packets by following the
       rules which are set up. Depending on these rules, the data
       packets are either rejected or accepted.

       Here are a few reasons why you should have a Firewall enabled.
       To protect your computer
       Many malware on the Internet enables an unknown man across the
       globe to have control over your computer. This is easily one of
       the worst situations you can ever face and a firewall actively
       stops something like that from happening.
       To Play Games Online Safely
       Online gaming is very common these days and everyone loves to
       spend some time relaxing. But, there is various malware which
       targets the online games existing on various compromised or
       unsecured game servers.
       You can block unwanted content with a firewall
       So far we have only talked about the ability of the firewall to
       block various dangerous content. But the firewall can do more
       than that. Other that protecting you against ransomware, a
       firewall allows you to block various online locations of your
       choice.
       Even though the firewall does a lot, it is still ineffective
       against various viruses, keyloggers, and worms. So, it is safe
       to say that a firewall is your last resort. You should always
       use it along with a goo anti-virus tool.
