can someone give a specific definition on what dmz is?

Demilitarized Zone

The demilitarized zone, a euphemism for that portion of a network that is protected by a simple firewall that provides basic security, but is usually configured to allow most traffic to flow. While the DMZ is not fully secure, it is safer than being on the Internet proper.

BTW google lately? I found this in about 10 secs.

A DMZ would look like this:

Code:

                                  WAN
                                      I
                                      I
                                  Router
                                      I
             DMZ Area          
                                      I
         Web Server                                      DNS Server   FTP Server
                                  Firewall
                                      I
                                      I
                               Local Lan

I hope that looks right on your machine. The Web Server, Firewall, DNS Server and FTP Server would all have Public IP Addresses and are usually physically connected to the same Ethernet switch. They would be protected by whatever firewall capabilities were in the router.
The Firewall device would be running NAT and protect all the devices on the Local Lan which would all be using private IP addresses.
