Diagram of a screened subnet using a single firewall device. By separating the firewall system into two separate component routers it achieves greater potential throughput by reducing the computational load of each router. As each component router of the screened subnet firewall needs to implement only one general task, each router has a less ...
In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network or screened subnet) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted, usually larger, network such as the Internet.

[1]: 1, 16 The practice of dividing a network into two or more networks is called subnetting. Computers that belong to the same subnet are addressed with an identical group of its most-significant bits of their IP addresses.
Firewall dual-homing provides the first-line defense and protection technology for keeping untrusted bodies from compromising information security by violating trusted network space. A dual-homed host (or dual-homed gateway [ 2 ] ) is a system fitted with two network interfaces (NICs) that sits between an untrusted network (like the Internet ...
