plug-and-play A feature, introduced 
with Windows 95, to simplify the use of 
some peripheral devices. Once the device 
has been installed (in accordance with the 
manufacturer’s instructions), you can plug 
it into the computer while the computer 
is running. The operating system auto-
matically 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.
processor (short for microprocessor). 
The brains of the computer. 
See microprocessor.
product key A unique series of letters 
and numbers that are 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 to enter in a customer 
database. Later, when you call 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.
program Software that you install on a 
computer for word processing, drawing, 
manipulating photos, reconciling your 
bank statement, calculating your taxes, 
composing music, or playing games. It is 
occasionally referred to as an application. 
See software.
Q
QuikDock A device that provides ports 
for external devices, allowing you to 
“dock” and remove your Notebook while 
your hardware remains connected to the 
QuikDock.
R
RAM (random access memory)
The main memory of the computer. 
It holds a copy of the operating system, 
any programs that are running on the 
computer, and any data that is being 
processed. RAM is temporary memory; 
turning off the computer clears RAM. 
The more RAM your computer has, 
the faster the programs respond.
See main memory. See also ROM.
