Equipment Description

OSI model	The model divides the functions of a protocol into a series of layers known as a
	’protocol stack’ (e.g., TCP/IP stack). Lower layers are implemented in hardware,
	while higher layers are used in software. Each of the layers is a transport platform
	for the next higher level and relies on the next lower level .
	The following image is a graphic representation of the OSI layers:
