INTERNET OF THINGS
TCP: - It is most widely used for data transmission in communication network such as
internet .it provides process to process communication using port numbers. It uses port
number for communication which keeps Track of segments that are received and
UDP: - It is the simplest protocol that involves minimum amount of communication
mechanism. It is connectionless, unreliable transport protocol. It does not provide
guaranteed delivery of the message.
An application layer protocol defines how application processes (clients and servers), running on
different end systems, pass messages to each other. In particular, an application layer protocol defines:
The types of messages, e.g., request messages and response messages.
The syntax of the various message types, i.e., the fields in the message and how the fields are
The meaning of the information that the field is supposed to contain.
Rules for determining when and how a process sends messages and responds to messages.
Application layer protocol enables process to process connection using ports.
