What is item unique identification
Biometric identifier.
Assuming you mean the IMEI number - it's a unique 17-digit number given to every handset. Each handset's number is unique - there are no two handsets with the same IMEI number.Mobile phone companies can block a handset using the IMEI numnber - and once blocked, it cannot be undone. Basically if the IMEI number is used to block a handset - it renders the handset permanently useless. The 'standard' unlock code for a handet can be bypassed and reset - an IMEI block cannot !
An IP address is the unique identifier assigned to any personal computer connected to the internet.
The IP address of course! Think about it. It's on the network layer, It is unique, and it's assigned to every device on the internet!
