The development of the Internet is rapidly changing the world and us. If you look closely at the development of the Internet, you will find that we used the Internet to retrieve information before. At this time, the Internet is connected to "people and information", which can be broadly called "people and things". With the rise of social networking sites such as Facebook,Twitter,Whatapps and Skype, the Internet connects people to people. The next development direction of the Internet is to connect "things and things"-we call it the Internet of Things.
Therefore, it is imminent to be familiar with and understand the Internet of Things.
First, let us understand the Internet.The Internet, also known as the international network, started from the Arpanet in the United States. It is a huge international network formed by interconnecting networks and networks according to a certain agreement; the Internet has become popular in daily life, providing people with information Inter-services, such as: paperless office, using computers or mobile phones to upload, update, and share data through the network in a timely manner.
The Internet of Things is a network that is further extended and expanded on the basis of the Internet. If the Internet is connected to computers, then the Internet of Things connects everything in the world. The Internet of Things transforms the status of objects into Various parameters are then uploaded through the Internet to realize data sharing, forming a network of all things, and the intervention of the Internet of Things has brought great convenience. For example: Scan code payment at the supermarket now, you can get the item and related information by scanning the price code of the item.
Now, they can leverage networks to enable communication with sensors, other machines and cloud platforms, in order to send important data back-to-base for actioning.
Continuing our example, a vending machine can now send an alert when it is low on stock - or if there is a fault - rather than remaining out of stock (or out of order) until maintenance can next attend the site.
So What Makes The Networks Different?
As mentioned previously, the capability to autonomously locate other devices is one of the features that sets an IoT mesh apart from a regular internet network.Typically, an internet connection would expect to find a relevant device and enforce linking with it for the purposes of enabling and maintaining network function.IoT devices, by contrast, utilize a network technology for connection with each other, and these nodes can communicate autonomously and with each other.
Further to that concept, an IoT framework is usually private and decentralized in the sense that currently, every IoT system operates independently of others. This means any new device must be appropriately configured before joining the loop, and of all the structures currently operating worldwide, none of them ever come into contact with another.
Conversely, a large part of the internet – despite starting life as a somewhat decentralized arrangement - now relies on a small handful of centralized servers. With the right tools a majority of the world can connect to the same Internet, but access to the “closed loop” of an IoT mesh requires custom engineering and access.
So to summarise, an IoT network is a closed-loop mesh of autonomously operating devices which can communicate with each other when required, while regular networks rely on readiness to connect with an external system.
