Refurbished

In the computer world refurbished means "old" or used computer equipment that has been restored to like-new working condition and/or appearance or systems that were returned to the factory to repair a flaw. Generally, refurbished pertains to hardware components that either have been replaced with similar components or newer, more up-to-date parts. Companies leasing machines are likely to "refurbish" the leased units and then sell them at a reduced price. In some cases, refurbished computers are donated to schools or charitable organizations.

Network card

A network card-or Network Interface Card (NIC)-allows a computer to physically connect to a local wired network. These cards come in various shapes and sizes depending on the computer model. There are several ways to see if a used or refurbished machine is equipped with a network card, but the easiest way is to check the machine's port panel. The panel is on the back of desktop models and on the sides and/or back of a laptop.

Factory direct

Any time a consumer buys an item directly from the manufacturer, they are purchasing "factory direct." The opportunity to buy this way was made possible by the development of e-commerce and merchandise catalogs. Dell Computers was one of the first to market their products directly. Purchasing items this way also tends to be more cost effective.

An open box computer is one that been returned after the buyer has "opened the box." In doing so, the product can no longer be considered new. Following inspection by a certified technician, the merchandise can be sold at a reduced or discounted price.
