- Devices can connect to a Bluetooth
enabled peripherals such as printers
or speakers
- Wi-Fi
- Another method of
wireless connection
using radio waves
- Wi-Fi enabled devices
can communicate over
longer distances.
- Most modern devices are Wi-Fi enabled.
- allows
devices to connect
with a computer
network and the
Internet
- allows devices to connect to Wi-Fi
enabled peripherals e.g. printers,
speakers
- when two devices, e.g. a media player and
computer, are connected they can
automatically exchange data
- synchronisation
- cloud synchronisation

- WORKED EXAMPLE
Explain why Simon
would want to
'synchronise' his
media player
- Synchronisation allows two connected devices to swap data
automatically. Simon can set the software, for example iTunes, to
update his media player with new or changed items on the computer.
If he has downloaded a new music file to the the computer or changed
some contact details, then the software will automatically update the
media player. The computer can also update the media player's
software if a new update has been downloaded to the computer.
