What is a Firewall and How Does it Work?
In brief, firewalls are hardware or software used to prevent unauthorized access to a computer system.

A version of the webpage is stored in the proxy server’s cache memory, allowing faster loading in the event you revisit the page later on.
In addition to the proxy server, firewalls sometimes provide a DMZ (Demilitarized Zone), or a perimeter network that homes low-risk files and customers which are outside the primary firewall. Since firms mainly use this feature, folks probably won’t need to think about it.
