Q1: What is the Internet-of-Things?
A1: It depends who you ask
Kevin Ashton, cofounder and executive director of the Auto-ID Center at MIT, first mentioned the Internet of Things in a presentation he made to Procter & Gamble in 1999. “Today computers -- and, therefore, the Internet -- are almost wholly dependent on human beings for information. Nearly all of the roughly 50 petabytes (a petabyte is 1,024 terabytes) of data available on the Internet were first captured and created by human beings by typing, pressing a record button, taking a digital picture or scanning a bar code. The problem is, people have limited time, attention and accuracy -- all of which means they are not very good at capturing data about things in the real world. If we had computers that knew everything there was to know about things -- using data they gathered without any help from us -- we would be able to track and count everything and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling and whether they were fresh or past their best.”

A2: Change the way we go from place to place?
The IoT connects data producers.
The IoT aggregates data sets.
The IoT enables on-demand data access to data consumers.
The IoT enables the consumption of data using standardized means.
You are what you eat. How can, will data be
consumed, and towards what ends?

Q8 Compatibility, Interoperability, Interchangeability?
A8a) Compatibility: The ability of two or more devices, applications, networks, or systems to coexist in the same physical environment – that is, operate without corrupting, interfering with, or hindering the operation of the other entity.
A8b: Interoperability: The ability of two or more devices, applications, networks, or systems to work together, and (more specifically) to reliably and securely exchange and
readily use data with a common shared meaning.
A8c: Interchangeability: The ability of two or more devices, applications, networks, or systems to be physically exchanged for each other and provide a defined level of identical operation without additional configuration.

Q9: What is PoE?
A9 PoE = Power over Ethernet – Combined power and data – Low voltage distribution – Established, standardized for other applications (e.g. phones, access points) – Potentially lower installation, configuration, maintenance costs
Bonus question: low voltage DC systems can have significant energy losses due to voltage drop. Is this a problem? Answer: Can be, but mitigated by larger gauge conductors, limited run lengths, distributed switches, system design
