A protocol can be defined as a set of rules determining the format and transmission of data or a set of rules that governs data communication. A protocol defines what is going to be communicated. The key elements of protocol are syntax, semantics and timing.

Syntax: Syntax relates to the structure or format of the data, meaning the order in which they are presented. For example; a simple protocol may expect the first 8 bits of data to be the address of the sender, the second 8 bits to be the address of receiver, and the rest of the stream to be the message itself.

Semantics: Semantics relates to the meaning of each section of bits. How is a specified pattern to be interpreted; and what action is to be taken based on that interpretation? For instance does an address identify the route to be taken or the final destination of the message?

Timing: Timing refers to two vital characteristics: when data should be sent and how fast they can be sent. For example if a sender produces data at 100 Mbps but the receiver can process data at only 1 Mbps, the transmission will overload the receiver and data will be largely lost.

Protocols are nothing but a rule and regulation of any program. It may include Syntax and semantics

Here some more description about these terms

1. Syntax: Syntax is nothing but a structure formate of data.

2. Semantics: The word semantics refers to the meaning of each section of bits.
