Protocol
In networking, a protocol is a 
standardized set of rules for 
formatting and processing data. 
Protocols enable computers to 
communicate with one another. 

A network protocol is a set of 
established rules that specify how 
to format, send and receive data 
so that computer network endpoints, 
including computers, servers, 
routers and virtual machines, can 
communicate despite differences in 
their underlying infrastructures, 
designs or standards.
