what is a network firewall

It's a network device that will block certain traffic from coming in, usually unless you, the client PC, first requested the data.

Basically it's like a bouncer at the bar, it will block all unwanted access from the outside internet to the computers behind the firewall. It also works to block unwanted traffic from the inside getting out.
