The '''protocol stack''' or '''network stack''' is an [[implementation]] of a [[computer network]]ing '''protocol suite''' or '''protocol family'''. Some of these terms are used interchangeably but strictly speaking, the ''suite'' is the definition of the [[communication protocol]]s, and the ''stack'' is the software implementation of them.<ref>{{cite web

Line 12:

Individual protocols within a suite are often designed with a single purpose in mind. This [[Modularity (programming)|modularization]] simplifies design and evaluation. Because each protocol module usually communicates with two others, they are commonly imagined as [[Abstraction layer|layers]] in a stack of protocols. The lowest protocol always deals with low-level interaction with the communications hardware. Each higher layer adds additional capabilities. User applications usually deal only with the topmost layers.<ref>{{cite web
