Linux Overview What is Linux? Linux is, in simplest terms, an operating system. It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions. The operating system (OS) relays instructions from an application to, for instance, the computer's processor. The processor performs the instructed task, then sends the results back to the application via the operating system. Explained in these terms, Linux is very similar to other operating systems, such as Windows and OS X.
PStart PStart doesn't neccessarily have to be installed to your hard disk. Execute the installer and choose: you can install PStart to your local hard drive or a removable device. Unlike Windows shortcuts, PStart uses relative paths, when installed as a portable application. If your USB key drive gets another drive letter when you insert it into another computer, your portable applications still can be started properly.

Demilitarized zone (computing) In computer security, a DMZ or Demilitarized Zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually 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 attacker only has direct access to equipment in the DMZ, rather than any other part of the network. The name is derived from the term "demilitarized zone", an area between nation states in which military operation is not permitted. In the military sense, a DMZ is not seen as belonging to either party bordering it. This concept applies to the computing use of the metaphor in that a DMZ which is, for example, acting as a gateway to the public Internet, is neither as secure as the internal network, nor as insecure as the public Internet.

PCI-e vs AGP What is PCI-Express and AGP? There are two ways to connect a graphics card to a motherboard, either via an AGP or PCI Express slot located on your motherboard. A motherboard only supports one of these slots, so if you’re looking for a new video card make sure you’re aware of whether your motherboard supports AGP, or PCI-Express. AGP has been the standard for a long time now, but it is old technology.
