As with IoT and other popular technology terms, there is no established consensus definition or set of criteria for characterizing what a smart city is. Specific characterizations VARY widely, but in general they involve the use of IoT and related technologies to improve energy, transportation, GOVERNANCE, and other municipal services for specified goals such as sustainability or improved quality of life.

The related technologies include:-

• Social media (such as Facebook and Twitter),
• MOBILE computing (such as smartphones and wearable devices),
• Data ANALYTICS (big data ? the processing and use of very large data sets; and open data ? databases that are publicly accessible), and
• Cloud computing (the delivery of computing services from a REMOTE location, analogous to the way utilities such as electricity are provided).

Together, these are sometimes called SMAC.
