engineering.purdue.eduThis 7-layer model of the protocols is referred to as the OSI (Open Systems Interconnection) model. In the literature on computer networks, you’ll also see an older 4-layer model in which the Application Layer is a combination of the top three layers of the OSI model. That is, the Application Layer in the 4-layer model combines the ...
Application Layer Functionality and Protocols
ptgmedia.pearsoncmg.comThe OSI model is a seven-layer model, designed to help explain the flow of information from layer to layer. Figure 3-1 Interfacing Human and Data Networks This chapter focuses on the role of Layer 7, the application layer, and its components: applications, services, and protocols. You explore how these three elements make the robust
Understanding Layer 2, 3, and 4 Protocols
ptgmedia.pearsoncmg.comOSI Seven Layer Model. When we talk about Layer 2 and Layer 3 networking, it is these layers that we’re referring to, and logically the further up the OSI model we move, the greater intelligence we can use in networking decisions. Each layer plays its part in moving data from one device to another across a net-
