Understanding Computer Terms

plug-and-play

A feature introduced with Windows 95 to simplify the use of some peripheral devices. Once the device is installed (in accordance with the manufacturer’s instructions), you can plug it into the computer while the computer is running. The operating system automatically recognizes the new device. In order to connect a non-plug-and-play device, you must first shut down the computer. See peripheral.

pop-up menu

A list of options that pops up when you right-click an icon on the desktop or taskbar, the vacant part of the desktop, a selection in a document, or a file in Windows Explorer. See right-click.

premastering

The process of preparing data to be recorded onto a CD. This includes dividing the data into sectors and recording those sectors with the appropriate header (address) and error correction information. In the case of recordable CD systems, premastering and mastering are done in one operation, resulting in a ready-to-read CD.

Processor (short for microprocessor)

The brains of the computer. See microprocessor

product key

A unique series of letters and numbers that is assigned to each software package you buy. You are asked to enter the product key when you install the software. When you register the software, you transmit the product key to the manufacturer for entry in a customer database. Registration activates your warranty. When you telephone for technical support, you are asked for the product key. The technician matches it against the database to determine whether you qualify for support. You should keep a record of all product keys to protect your investment. They are comparable to the serial numbers

on hardware. See software.
