Spam represents more than 80% of the email traffic in the world. Computers operating as part of a botnet can be used for tasks even more malicious and dangerous than spam: distributed denial-of-service (ddos) attacks that rise up to disable even the most well- protected internet hosts (cid:862)(cid:272)itize(cid:374) jour(cid:374)alis(cid:373)(cid:863) Term coined in the late 1990s by a group based at mit known as auto-id.

Instead of having a barcode, they have computer chips with memory and low- power radio frequency identification device (rfid) that allows nearby receivers to query the object and determine the status.
