What is the main difference between HTTP and CoAP protocols?
- CoAP is designed for Machine to Machine (M2M) applications, while HTTP is not. (correct)
- HTTP is designed for use with constrained nodes and networks, while CoAP is not.
- HTTP is a lightweight RESTful (HTTP) interface, while CoAP is not.
- CoAP is a session layer protocol, while HTTP is not.
What is the basis of the Client-Server interaction in CoAP?
What is the basis of the Client-Server interaction in CoAP?
- The Client-Server interaction is asynchronous over a datagram oriented transport protocol such as TCP.
- The Client-Server interaction is synchronous over a datagram oriented transport protocol such as TCP.
- The Client-Server interaction is asynchronous over a datagram oriented transport protocol such as UDP. (correct)
- The Client-Server interaction is synchronous over a datagram oriented transport protocol such as UDP.
What is the purpose of CoAP's Representational State Transfer (REST) interface?
What is the purpose of CoAP's Representational State Transfer (REST) interface?
- To enable high-power sensors to use RESTful services while meeting their power constraints.
- To provide a lightweight RESTful (HTTP) interface for high-power sensors.
- To enable low-power sensors to use RESTful services while meeting their power constraints. (correct)
- To provide a heavyweight RESTful (HTTP) interface for low-power sensors.
