Your questions answered.

What is a firewall and do I really need one?

 There are 2 types of firewalls, software based and hardware based. They both do the same thing just in a little different way but mainly they block ports on your PC. A port is like a doorway that connects certain programs to the internet, for instance port 25 and 110 are the incoming and outgoing mail ports for most common e-mail programs while port 80 is your browsers port to the internet such as Internet Explorer and Firefox. Software firewalls simply close ports that are not in use but keep open ports that are commonly used. If you have one computer connected to a cable modem then you would want to make sure you have a software firewall active. All Windows based PC’s after Windows 98 have a built in firewall. If you have a router and have several computers sharing your internet connection the router acts as a hardware firewall separating your computers from the prying eyes of intruders. All computers should utilize a firewall for home users on a dynamic IP address the odds of being hacked into are as good as the odds of you winning the Powerball; static IP users, that’s a different case all together as the hackers have all the time in the world to get into your systems so lock them down tight.
