What layer of OSI is a printer?

What layer of OSI is a printer?

The user needs be connected to a network ( layer 1 and 2 ) , needs an IP address ( layer 3 ) , needs connect to the server ( layer 4 ) and finally exchange the file to be printed with the printer server (layer 5,6,7 ; the printer queue). So , many of the layers are present during any communication.

What is OSI model PDF?

The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it.

What is OSI model in computer?

Why is OSI used?

The purpose of the OSI reference model is to guide technology vendors and developers so the digital communications products and software programs they create can interoperate and to promote a clear framework that describes the functions of a networking or telecommunications system that’s in use.

Who created OSI?

the International Organization for Standardization (ISO)
The OSI model was developed by the International Organization for Standardization (ISO), so some sources confusingly call it the ISO model, or even the ISO OSI model. The model is formally called “X. 200: Information technology—Open Systems Interconnection—Basic Reference Model.”
