A firewall is a device, or a piece of software that is placed between your computer and the rest of the network (where the hackers are!)
If you wish to protect your whole LAN from hackers out on the Internet, you would place a firewall between the LAN and the Internet connection.
A firewall blocks unauthorised connections being made to your computer or LAN. Normal data is allowed through the firewall (e.g. e-mails or web pages) but all other data is blocked.
In addition to physical devices, firewalls can also be software. In fact most computer operating systems have a software firewall built in (e.g. Windows, Linux and Mac OS)
