A simplified definition for a network firewall is that it is a tool that implements the traffic checking that has to be done (for security purposes) among two or more networks.

You may have heard the term firewall before but have you ever wondered how does a firewall work and why do I need one? A computer firewall protects your computer by putting up a barrier to keep anyone from accessing your files when you are surfing the Internet.

There are many different types of viruses, some are just annoying and may cause a message to flash on your screen, while others are more malicious and can actually delete files necessary for your computerís operating system. There are others that can also leave your computer open for hackers to do as they please with your computer.

Gone are the days when you would have been laughed at if you walked into an all-night LAN party carrying your trusty laptop and expecting to hang with the giant computer towers standing at everyone’s feet. The gaming laptop computers of today sport huge, crisp LCD screens, cutting-edge video cards and full-size keyboards. Not only can these gaming laptop computers hang with the standard clunky computer tower, but they can also be ordered fully custom to meet the exact specifications of any gamer.
