5. _________ is uniquely identifiable embedded computing devices.
a) Internet
b) IoT
c) Bigdata
d) Cloud
Answer: b
Clarification: The IoT is the part of the Internet that is made up of “uniquely identified embedded computing devices,” as Wikipedia status. Just like the world Wide Web is a Internet, so does the IoT.
6. Web is a mesh of computers, so too is _________
a) IoT
b) Bigdata
c) Cloud
d) Internet
Answer: a
Clarification: Just like the World Wide Web runs over the Internet, so does the IoT. Similarly to how the Web is a mesh of computers, so too is the IoT.
7. Without _________ computers embedded in house keys are worthless.
a) Data
b) Services
c) Both Data and Services
d) Neither data nor services
Answer: c

8. _________ Services are the way in which the IoT is connected to data.
a) Cloud
b) Bigdata
c) Internet
d) Network
Answer: a
Clarification: Cloud based services are the way in which the IoT is connected to data. Just like World Wide Web runs over the Internet, so does the IoT.
9. APIs are the skybridge.
a) True
b) False
Answer: a
Clarification: APIs are the skybridge – IoT on one side, useful information and plentiful data crunching capabilities on the other. APIs make IoT useful, turning limited little things into powerful portals of possibilities.
