Question - 52 : - What is the difference between M2M and IoT?
Answer - 52 : -
The difference between M2M and IoT is:
| M2M | IoT |
| Communication is done within an embedded software at the client site. | Communication is done for grand-scale projects. |
| It uses isolated systems of devices having the same standards. | It uses integrated devices, applications, and data across varying standards. |
| M2M offers limited scalability options. | IoT is inherently more scalable. |
| A cellular network or wired network is used for device connectivity. | It uses an active Internet connection for device connectivity. |
| Machines can communicate with one machine at a time. | Many machines can communicate with each other over the Internet. |
