A firewall is a piece of software that blocks any unauthourised entry to or from your PC.

It is a software program that in theory stops unwanted files/cookies, from being placed on your PC.

It is rather like a wall blocking all attempts to communicate with your PC unless you give permission.

a fire wall is a program that can be configured to block access to and from the internet blocking access to the internet comes in the form of blocking programs from your computer going onto the internet and blocking coming in generally refers to people who scan ip adresses and look for computer with weaknesses generally known as hacking a good firewall will totaly mask your system from the internet so these scans cant see you

A firewall can be software or hardware based.

The home user a software based firewall is ideal.
