EchoLink
EchoLink software allows licensed Amateur Radio stations to communicate with one another over the Internet, using streaming-audio technology. The program allows worldwide connections to be made between stations, or from computer to station, greatly enhancing Amateur Radio’s communications capabilities. There are more than 200,000 validated users worldwide — in 162 of the world’s 193 nations — with about 5,000 online at any given time.

D-Star
D-STAR* (Digital Smart Technology for Amateur Radio) is an exciting new form of Amateur Radio that compliments other parts of the hobby including VHF, HF operation, Contesting and Satellite communications etc. Utilising digital communication and the Internet, D-STAR allows you to communicate worldwide with other operators who are connected to D-STAR* repeaters.

QSONet (CQ100)
QsoNet uses the internet to receive audio signals from a ham radio transmitting station, then instantly reflects the audio back to all stations listening on that frequency. There is no RF. Everything is done over the internet. The result is a simulated ionosphere for worldwide amateur radio communication. Stations can use voice, CW (Morse code), PSK and FSK modulation.

That’s the official descriptions out of the way but what actually are they and where do I think they fit into amateur radio.
