DMZ (computing) the router has no programming to handle (6in4 or GRE tunnels are prototypical examples). DMZ (computing) 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 network, usually a larger network such as the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN): an external network node can access only what is exposed in the DMZ, while the rest of the organization's network
Task computing Task computing Task computing is a computation meant to fill the gap between tasks (what the user wants to be done) and services (functionalities that are available to the user). Task computing seeks to redefine how users interact with and use computing environments. It is built on pervasive computing. A Task Computing Framework (TCF) is a framework that supports task computing, by providing support for: This definition of a task computing framework does not make reference to computational components. This is referred to as a Task Computing Environment (TCE). A TCE is a computational system that includes, at a minimum,
