In the last two decades, the advancement of computation technology has produced more powerful processors, storage, and memory devices for low prices. Eventually, many physical things will be embedded with more computation capabilities and interconnected via the Internet in a cost-effective manner. This will lead IoT to the next level, which enriches the idea of Ubiquitous Computing that Mark Weiser came up with in 1988. That is, bringing computation into the physical world and making effective use of computer technologies.

This article covers a rarely discussed topic; ubiquitous computing and how IoT will lead achieving its characteristics.
