Class 11 Computer Science Chapter 3

SUMMARY : Class 11 Computer Science Chapter 3

Artificial intelligence (AI) endeavours to simulate the natural intelligence of human beings 
into machines thus making them intelligent.

Machine learning comprises algorithms that use data to learn on their own and make predictions.

Natural Language Processing (NLP) facilitates communicating with intelligent systems using a 
natural language.

Virtual Reality (VR) allows a user to look at, explore and interact with the virtual surroundings, 
just like one can do in the real world.

The superimposition of computer-generated perceptual information over the existing physical 
surroundings is called Augmented Reality.

Robotics can be defined as the science or study of the technology primarily associated with the 
design, fabrication, theory and application of robots.

Big data holds rich information and knowledge which can be of high business value. 
Five characteristics of big data are: Volume, Velocity,  Variety, Veracity and Value.

Data analytics is the process of examining data sets in order to draw conclusions 
about the information they contain.

The Internet of Things (IoT) is a network of devices that have an embedded hardware and software 
to communicate (connect and exchange data) with other devices on the same network.

A sensor is a device that takes input from the physical environment and uses built-in computing
resources to perform predefined functions upon detection of specific input and then processes data
before passing it on.

Cloud computing allows resources located at remote locations to be made available to anyone 
anywhere. 

Cloud services can be Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and 
Software as a Service (SaaS).

A grid is a computer network of geographically Notes dispersed and heterogeneous computational
resources.

Blockchain is a system that allows a group of connected computers to maintain a single updated 
and secure ledger which is updated only after all the nodes in the network authenticate the 
transaction.
