Hi and Welcome to Steve’s Internet Guide.

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).

Although the Internet of Things will make use of the existing Internet protocols and Internet technologies it will introduce new technologies,protocols and services.

SeeThe Internet of Things ( IOT) for Beginners

This site will focus on explaining and using those important IOT technologies and services. Below are some quick links to get you started.

Many of the APIs today are Web API’s designed to access web services like Facebook ,Twitter etc. Because of their widespread use most IOT services (AZURE,AWS,Bluemix)  also support http based APIs.

To understand and use an http API you will need a reasonable understanding of the following: (more…)

When sending and receiving data in IOT applications and APIs you will encounter JSON formatted data.

Having a good working knowledge of JSON and how to create and use JSON data will be very important in developing IOT applications. (more…)
