Glossary
DVR: Short for Digital Video Recorder, this
abbreviation refers to any device capable of
recording and saving a digital video file. This is the
high-tech equivalent of a VCR.
GB: GB is short for gigabyte which is a unit used
to measure computer storage capacity and is
approximate to 1.07 billion bytes. 1 Gigabyte of data
is almost twice the amount of data that a CD-ROM
can hold. Additionally, 1 Gigabyte could hold the
contents of about 10 yards of books on a shelf.

LED: An abbreviation for "light emitting diode," it's
an electronic device that lights up when electricity
passes through it. LEDs are good for displaying
images because they can be relatively small, and
they do not burn out. However, they require more
power than LCDs.
Root Directory: A root directory is the first directory
on a drive or disk. For example, when connecting a
removable drive to a Windows computer, it will be
assigned a drive letter (ex. C:, D:, E:). When opening
that drive, the first window listing the contents of the
drive is the root directory.
