Firewall -

A firewall refers to either a software or hardware device that basically protects your internal network from any outside threat or any unauthorized Internet access from the inside.

If you have a constant connection to the internet (i.e. non-dialup), you can be "hacked" into if you don't have some kind of firewall protection (ok, you can still get hacked into even with a firewall or regular dial up, but it's harder). It's mostly larger companies with networks connected to the internet who need firewalls.

However, with the proliferation of cable and DSL connections, lots of residential customers are finding they need some form of firewall protection as well. In fact, I recently read that hack attacks on these residential connections is on the rise and may gain the unfortunate prize of being the most common hacking target in the very near future.
