NETWORKING TOOLS, EQUIPMENT, & MATERIALS OSI LAYERS Open Systems Interconnection Dates back to the late 1970’s It is a layered framework for the design of network systems that allows communication between all types of computer systems. Has 7 layers Each of which defines a part of the process of moving information across a network. APPLICATION SERVICES APPLICATION DIAGRAM OSI MODEL LAYERS Application Layer Protocols functioning at the Application layer work with the applications you use to communicate over the network Allows the end user’s access to the network by providing a set of utilities for application programs. 5 COMMON CATEGORIES OF SERVICES Presentation Layer The presentation layer formats the data for presentation to the user. Data presentation - ensures that the data being sent to the recipient is in a forma.
