IDG Contributor Network: HTTP and DNS in a 5G World
The internet has of course been wildly successful over the last thirty years as more and more functionality has moved online. A large part of this success has been due to two key protocols that have allowed the internet to scale relatively gracefully: HTTP which stands for Hypertext Transmission Protocol, and DNS which stands for Domain Name System. HTTP is the protocol used to send data between a web browser running on a laptop or mobile phone and the web page or application that it is communicating with, which is running on a server in the network. No matter where the web page is located or who develops the web browser, it is guaranteed that they will be able to interoperate because they all use the standardized HTTP protocol to communicate.
