Steve’s Internet Guide

Hi and Welcome to Steve’s Internet Guide.beginners guide internet-and-networking

The first wave of the Internet involved connecting people to each other and people to information.

The next wave of the Internet will involve connecting the physical world to the Internet, and machines to each other (M2M – Machine to machine).

Every object, both real and virtual, connected to, and accessible over the Internet is the basic idea of the Internet of Things or the internet of Everything.. See- Beginners Guide to IOT

One of the protocols I believe will be crucial in the coming years is MQTT and it will form the main focus of this site.
