A firewall works much like the physical security at my old workplace. It lets people in if they are allowed, and keeps them out if they aren't allowed. A firewall is a buffer between the outside world and the sensitive resources within. It can disallow certain kinds of traffic, based on the port by which the traffic is trying to enter. The better the firewall is, the more methods are at its disposal to admit only desirable traffic.
Some advanced firewalls can even fight back against intruders.
