SD Card
(Secure Digital)
The Secure Digital Card was developed in
2001 by SanDisk on the basis of the older
MMC standard. An SD card is a re-writa-
ble change-over storage card.
Stylus
A stylus is an input pointer which is used
for the operation of touch-screens, mobile
phones or PDAs.
The stylus consists basically of a plastic
pointer with a softer plastic core. The
sleeve is hard and can be gripped and the
softer core emerges at the tip and is de-
signed to touch the screen as softly as pos-
sible (i.e. without the danger of scratching
the screen).
The stylus is more accurate than operation
using the fingers, since only the thin tip
touches the screen. In addition, dirty
marks on the screen caused by finger
prints are avoided.
USB
(Universal Serial Bus)
The Universal Serial Bus (USB) is a bus
sytem for interconnection of a computer
with external USB peripherals for the ex-
change of data.
