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.
LCD: Abbreviation of “liquid crystal display.” LCD screens are
thin, flat electronic displays.
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.
