Explain Bluejacking and Bluesnarfing

What will be an ideal response?

With Bluejacking, someone you do not know may send your Bluetooth phone contact information or text messages that you may inadvertently add to your phone's electronic address book. If this data is unintentionally added to your list of contacts, messages from that unknown user could be automatically opened because to your Bluetooth phone the message is from a known source. Bluesnarfing is perhaps more dangerous in that it allows an unauthorized user, or hacker, to remotely access your Bluetooth phone to make calls, send messages, or change data on your phone that you may not be aware of.
