The three important concepts in the Federal Networking Council's definition of the Internet are, namely;
Packet switching
The TCP/IP communications protocol
Client/server computing
Explanation:
Packet switching involves the transfer of data which are grouped into different packets and then sent over a digital network to their respective destination. After the data are received at the destination site, they are then extracted and used by the application software.
The transmission control protocol/internet protocol allows one computer to connect or communicate with another one through the internet. The internet protocol defines how to route and address each packet to ensure it gets to the right destination. The IP address of a particular device on a network is usually unique to that device.
Client/server computing describes how a server provides services by taking requests from clients computers and sharing its resources with one or more computers.
