Tech Glossary – P to R

Partition

A partition is a section of a hard disk. When you format a hard disk, you can usually choose the number of partitions you want. The computer will recognize each partition as a separate disk, and each will show up under “My Computer” (Windows) or on the desktop (Macintosh).

PCI Express

First came PCI, then PCI-X, then PCI Express. PCI Express can be abbreviated as PCIe or, less commonly and more confusingly, PCX. Unlike earlier PCI standards, PCI Express does not use a parallel bus structure, but instead is a network of serial connections controlled by a hub on the computer’s motherboard. This enables PCI Express cards to run significantly faster than previous PCI cards.

Plug-in

A software plug-in is an add-on for a program that adds functionality to it.

Quad-core

A quad-core CPU has four processing cores in a single chip. It is similar to a dual-core CPU, but has four separate processors (rather than two), which can process instructions at the same time.

RAM

RAM is made up of small memory chips that form a memory module. These modules are installed in the RAM slots on the motherboard of your computer.

Reimage

When you reimage a hard disk, you restore the entire disk from a disk image file. Since this restore process involves erasing all the current data on the hard disk, it is typically used a last resort system recovery option.
