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.
