LCD
Short for Liquid Crystal Display. Flat notebook display technology using liquid crystals (and
light polarisation) to provide sharp, flicker-free images on a screen comprised of millions of
tiny cells. Color can be produced by two basic techniques. Passive matrix is the less expensive
of the two technologies. The active matrix technology (or TFT) produces better quality but
is also more expensive.
LED
Short for Light-Emitting Diode. A semiconductor device that lights up when electricity passes
through it.
Lithium-ion battery
A lithium-ion battery uses lithium cobalt oxide and carbon as electrodes and ions move from
one electrode to the other during charge and discharge. Lithium-ion batteries are the first
choice for notebooks because of their light weight, high energy density and because they
have no memory effect. In addition they do not use heavy metals like lead, mercury or
cadmium.
MAPI
Short for Messaging Application Program Interface. A Microsoft Windows interface
enabling you to send e-mail messages. It allows e-mail access and distribution among
