Networking and The Internet of Things (IOT)

Hi and Welcome to Steve’s Internet Guide.
Home network and Internet

In 2011 over 2 billion people where connected to the Internet (Wiki),and over the past 10 years the Internet has become just as important as TV, radio, and the telephone.

Daily internet usage continues to grow and Internet access is vital to our daily lives.

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.

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.

Networking

The Internet is a network of interconnected computers and other devices.

Although the existing network infrastructure will continue to used, the Internet of things is also going to require a new infrastructure consisting of new protocols, hardware and technologies.

Although new protocols and technologies will appear at the data link and application level the main focus of this site will be on application level protocols like MQTT.

The Physical Web

The physical web is a project being championed by Google which uses Beacon technology to connect objects to the Web.

Just like the WWW became the main component of the Internet and HTTP became the primary protocol the physical web idea could do the same for the IOTs.

Here’s a good introductory video from Google.
