Answer:
4. Supervised learning.
Explanation:
Supervised and Unsupervised learning are both learning approaches in machine learning. In other words, they are sub-branches in machine learning.
In supervised learning, an algorithm(a function) is used to map input(s) to output(s). The aim of supervised learning is to predict output variables for given input data using a mapping function. When an input is given, predictions can be made to get the output.
Unsupervised learning on the other hand is suitable when no output variables are needed. The only data needed are the inputs. In this type of learning, the system just keeps learning more about the inputs.
Special applications of supervised learning are in image recognition, speech recognition, financial analysis, neural networking, forecasting and a whole lot more.
Application of unsupervised learning is in pre-processing of data during exploratory analysis.

Answer:
In 2000, a basic internet application cost businesses approximately $150,000 per month. In mid-2016, operating the same application in Amazon's cloud cost approximately $1,000 per month.
Explanation:
The role of cloud services cannot be overemphasized. Providing Infrastructure as a service (IaaS), Platform as a service (PaaS) and Software as a service (SaaS) cost a lot as there were very few cloud service providers and most services were yet to be integrated to the cloud.
But as at 2016, the cost on applications dropped as we have experienced an exponential growth in cloud services and applications, we now have Internet of Things (IoT) and other cloud infrastructure.
