The OSI Model

Paper Summary:

This paper discusses the open system interconnection (OSI) model, a critical component in the proliferation of computer networks in the work environment. It provides a definition of the model and looks at how the open system interconnection is used to implement protocols in seven layers by analyzing each of the layers in turn. The seven layers are: application, presentation, session, transport, network, data link and physical.

From the Paper:

"During the second phase of the application layer involves network redirection. "The Network Redirector is a TSR (Terminate and Stay Resident) program: it presents the network hard disk as another local hard disk to the CPU." ("Introduction to Networking: and Data Communications") The purpose of the network redirector is to find out whether or not a local or network drive is being requested. The network redirector then proceeds to pass on the request for a local driver to DOS and a request for the network driver to the network operating system. ("Introduction to Networking: and Data Communications") Network Aware applications such as client server databases, email, remote logons and file and printer servers are all components of the application layer."
