These technologies to work need internet protocols to allow them to send data through out the internet . These technologies are :
Peer to Peer : this protocol makes the clients that want the data into “servers” . This splits up the data to different computers and you give and take data as you are connected . Unlike other protocols which degrade with more users peer to peer increases performance as more users join in, but suffers from “leechers” that only download the files but never upload back causing a degradation in performance.
TCP/IP : is a protocol that consists of a Client and a Server . This means that most of the time your download speed is only limited by your Isp and the amount of people connected to the server . It is the most stable of protocols but degrades in performance as more and more users connect to it .
UDP : User Datagram Protocol is a protocol which is much faster than TCP/IP and has less latency than other protocols it is used for things likes VOIP and online games that need a fast connection. Although UDP is fast is easily prone to interference and will continue sending packets even if a packet is lost .
