A firewall (in computer/networking terms) is a software program or hardware device that intercepts communications between your computer and the outside network and does some processing on them to help block malicious connections.
Software programs install on your computer and are somewhat less effective, but can also offer more features. They only protect the computer they are installed on and must be started and functional in order to work.
Hardware firewalls are dedicated devices that sit physically between your computer and the network (internet, etc). They are always on and tend to do a better job because there is no program to start or crash on the PC. However, it's harder for the average user to control what programs can connect out from a hardware firewall.
Firewalls aren't absolutely necessary, but quite recommended. There are thousands of sources on the internet for malicious activity, they'll scan the network you're connected to and try to take your PC over for a variety of reasons (sending spam, etc). Very few internet connections are immune to this, though some ISPs sell modems (cable, dsl, etc) with built-in firewalls.
As the name suggests it is a virtual wall which protects your computer from outside threats from internet like Hackers, Viruses, Trojans, Spywares etc.
