4. Explain the following along with their applications.
a) Artificial Intelligence
b) Machine Learning
Answer –
a) Artificial Intelligence – Artificial intelligence (AI) is the simulation of human intelligence in devices that have been designed to behave and think like humans. The statement can also be used to refer to any computer that demonstrates characteristics of the human intellect, like learning and problem-solving.

b) Machine Learning – Machine Learning is a subfield of Artificial Intelligence to mimic intelligent human behaviour. Similar to how people approach problem-solving, artificial intelligence systems are employed to carry out complex jobs.

5. Differentiate between cloud computing and grid computing with suitable examples.
Answer – Because of cloud computing, the system is always accessible. In order to provide a setting where several computers can work together to complete a task as needed, grid computing refers to a network of the same or various types of computers. Also capable of working alone is each computer.

Example of Cloud computing – Gmail, Dropbox, Facebook, Amazon Web Services etc.
Example of Grid Computing – Online Games, Entertainment Industry, Database, WebLogic Application Servers etc.

6. Justify the following statement:
“Storage of data is cost-effective and time saving in cloud computing.”
Answer – Because the cloud vendor manages everything, using cloud storage is both time and money efficient. We don’t need to spend money on hardware resources, power, or support to manage and store data.

7. What is on-demand service? How it is provided in cloud computing?
Answer – On-demand self-service, customers can purchase, customize, and install apps via cloud service catalogues without the help of a skilled professional. The resources could be kept up by the user’s company or supplied by a cloud service provider.
