internet of things

definition

Idea of physical objects communicating and

interacting with each other online

Extends internet connectivity beyond

traditional devices like desktop and

laptop computers, smartphones and tablets

to a diverse range of devices and everyday

things that utilize embedded technology to

communicate and interact with the external

environment, all via the Internet.

History

Kevin Ashton, co-founder and executive director

of the Auto-ID Center, is credited with coining

the term the Internet of Things.

Currently, there are more than 12 billion

devices that can connect to the Internet.

HOW IT

IS DONE?

online network of physical objects is

accomplished through the use of RFID tags

and other types of sensors.

Implanting these tags inside a physical object

gives it the power to be monitored and

controlled remotely through the Internet.

eliminates the need for humans to constantly

enter and monitor data.

chip typically is capable of carrying 2,000

bytes of data or less.

Types

RFID tags that contain their own power

source are known as active tags. Those

without a power source are known as passive

tags.

RFID tagging is somewhat controversial

because the tags could theoretically be cloned

or used for illicit tracking.
