Explanation:

Internet of things (IOT) Communication between computers started with the Electronic Data Interchange that made direct communication possible between two PCs. All the computers connected to the Internet can talk to each other. Use of mobile phones for connecting internet has revolutionized the entire scenario. With Internet of Things the communication is extended via Internet among all the things that surround us.
At the first look, it may appear that Machine-to-Machine (M2M) communications and IoT denote the same thing. In reality, M2M is only a subset of IoT. IoT is a more encompassing phenomenon because it also includes Human-to-Machine communication (H2M). Radio Frequency Identification (RFID), Location-Based Services (LBS), Lab-on-a-Chip (LOC), sensors, Augmented Reality (AR), robotics and vehicle telematics, which are some of the technology innovations that employ both M2M and H2M communications. Their common feature is to combine embedded sensory objects with communication intelligence and transporting data over a mix of wired and wireless networks.
