Data communication refers to the digital transmission of data between two or more computers via a network. It involves a message, sender, receiver, communication channel, and protocol. Emerging communication technologies discussed include the Internet of Things, artificial intelligence, 5G wireless networks, driverless cars, smart cities, and Li-Fi visible light communications. Li-Fi uses LED light bulbs to transmit data at speeds up to 224 gigabits per second.

6. The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital
machines, objects, animals or people that are provided with unique identifiers and the ability to
transfer data over a network without requiring human-to-human or human-to-computer interaction.

11. Artificial intelligence is a branch of computer science that aims to create intelligent machines. It has become
an essential part of the technology industry.
The core problems of artificial intelligence include programming computers for certain traits such
as:
•Knowledge
•Reasoning
•Problem solving
•Perception
•Learning
•Planning
•Ability to manipulate and move objects

12. 5G
 5G is the coming fifth-generation wireless broadband
technology based on the IEEE 802.11ac standard
 5G will provide better speeds and coverage than the
current 4G.
5G operates with a 5Ghz signal and is set to offer speeds
of up to 1 Gb/s for tens of connections or tens of Mb/s for
tens of thousands of connections.

13. Why using 5G !!

14. A driverless car (sometimes called a self-driving car, an automated car or an autonomous
vehicle) is a robotic vehicle that is designed to travel between destinations without a human
operator.

15. Light Fidelity or Li-Fi is a Visible Light Communications (VLC) system running wireless
communications travelling at very high speeds. Li-Fi uses common household LED (light emitting
diodes) light bulbs to enable data transfer, boasting speeds of up to 224 gigabits per second.
