Protocol: Protocol is used to define a method of transmitting data over a computer network such as LAN, internet, and intranet. Each protocol has its special techniques, like how the data is formatted, when we sent, what to do with it once we received and how to check the errors in data. Generally protocol is in the form of packets, through packets only the data will send and receive it. There are hundreds of protocols has been developed for special purposes and environments. One of most common and known protocol is HTTP (Hyper Text Transfer Protocol), TCP (Transmission Control Protocol) which is used to transmit the data through internet.

A syntax protocol can be applied in many phases of computer programming and networking, as well as internet protocol, operating system protocol, texting and mailing protocol. It has special languages that will communicate with components and interact with one another.
Semantics: Semantics communicates with each section of bits such as how it will specify the pattern to be interpreted and what action is to be taken based on that interpretation. Finally it will identify the route to send the message to the final destination.
Timing: It discussed about two characteristics, one when the data should be sent and second how fast the data can be sent. Sometimes when data is transmission there will be chances for overload due to that a huge data will be lost.
Protocol Architecture:
There is several protocol architecture which will be defines the objects and procedures how the data will exchange between the devices. For example TCP/IP protocol architecture, it has a five layers and the model is known as DARPA (Defense Advanced Research Project Agency). The five layers of DARPA model are
• Application
• Transport
