It's nice to surf the net, browse cool websites and play online games. But do you ever think that your computer is at risk by the time you are doing all these stuff? Yes. Your computer is in a big risk. Keep your computer safe while getting in the Internet. How? Use a Firewall to secure your computer from offensive Internet sites and even from online hackers. What does a firewall do?
Firewall serves as a block or a wall in your computer from the Internet and in a computer from another computer inside a network. It neutralizes every data-entry that goes out from your computer to the Internet and from the Internet to your computer. It is somehow similar with the physical firewall that blocks your house from physical fires. Thus, keeps your house safe from being burned and/or blocks an entry from any unauthorized person.
For a more technical definition, a firewall is a software or hardware, designed to filter online information from the web to your computer. When you go to a website you send in information from your computer to the Internet. This information is considered as special commands. Each special command (data) is sent through packets. The packets sent need to abide online rules that are virtually set. If a packet fails to abide it, it will be discarded inside the network, meaning, it will not reach it's destination. Firewall is designed to work that way. It will not let unauthorized packets to get in through such network passage without complying on the protocol.
There are several types of firewall. Two common firewalls: Personal firewall (which is a special program installed in your computer), Virtual or Online Firewalls (which resides inside the Network). Personal firewall protects the computer itself while Online firewall protects the online network (the Internet).
