in technical terms i seriously dont understand what a firewall and proxy settings are.give a clear xpalnation?

Answer 1

A proxy is one can say a another puter which acts indirect when you surf. for example can a proxy have a big cache so you got pages faster.

your pc<>proxy>
a firewall is at most basic level a mediator who permits or deny trafic.
a router acting as a firewall can for example allow all tcp traficc at port 80 in and out byt deny all trafic on port 81. Firewalls can either be hardware and/or software based

Answer 2

1) A firewall's purpose is to control the passage of packets of data passing between your PC's NIC and the Internet through the selective blocking or opening of TCP-IP ports, these ports allow very specific protocols to communicate over many type of physical media.
2) A proxy stores your website history and will allow you to connect to the same website in a cached state, which results in a faster connection (since content is available even when offline).

Although they are sometimes thought of interchangeably, they each have functions which control the passage of web traffic.

Hope this helped.
