Module 1: Introduction to Emerging Technologies

The key points from this module are:
Cloud computing is an information technology service model where computing services that include both hardware and software are delivered on-demand to customers over a network in a self-service fashion, independent of device and location.
The four types of cloud service models are:

Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
Software as a Service (SaaS)
Data as a Service (DaaS)

The Internet of Things(IoT) consists of a large number of devices that are connected via the internet to sense and respond to conditions in their environment. These devices are typically sensors and actuators that exchange information with the controlling software for a defined purpose.
The two categories of sensors are:

Simple sensors
Smart sensors

Actuators are tools or mechanisms that can change their own state and or the state of other devices and machines.
Privacy is the right to be left alone and the right to be free of unreasonable personal intrusions, surveillance, or interference from other individuals or organizations.
Big data stands for huge volumes of data, produced by both humans and machines at a very high rate and with a massive variety.
The three categories of data are:

Structured data
Semi-structured data
Unstructured data
