proxies.. what is that?

i think this link will be helpful for you http://en.wikipedia.org/wiki/Proxy_server

Proxy is like a temporary ID, instead of your real I.P. address, a different I.P. address will show because the Proxy covers everything for you. Example: visiting a site that blocks any Philippine I.P address but if I use proxy , it's possible I can enter the website because the proxy might be carrying an I.P. that is not located in the Philippines.
