Machines are the tools that give the human a leverage to do a task in less time and efficiently. Every one now a day is surrounded with lot of machines but a limitation of machines is that we need a person to operate them these machines cannot run without a human .M2M (Machines to Machine communication) is the solution of that problem . Internet of Things (IoT) is subset of M2M and it takes the machines to machine communication to another level. Internet of Things makes use of internet to communicate with the things. Here thing can be any machine that have a unique identity on internet. Internet of Things allows machines to communicate with other machine as well as control them .This paper describe the basic structure of Internet of Things and how things work in Internet of Things. We describe CoAP (Constrained Application Protocol) that is the backbone of Internet of Things.
