Application is the top layer, while Physical is the bottom layer.
Any book/publication referring to an OSI layer as "First" should be sent back to the publisher as defective.
The top most layer is the application layer and bottom most layer is the physical layer. Since data is transferred from top to bottom, I would say that the starting layer is the application layer.
First layer of the OSI model covers the cabling and electrical signaling. The first layer of OSI model is the physical layer. The physical layer also decides the transmission mode and physical media.
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
The Seven layers of the OSI model are: Application Presentation Session Transport Network Data-Link Physical I think the answer to your question is the Application layer.
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
There are 7 layers in the OSI model which are from top to bottom: application layer / presentation layer / session layer / transportation layer / network layer / data link layer / physical layer
The first layer called the physical layer.
it comes in the first layer, or popularly known as the physical layer. must not be confused to be in datalink layer.
hub work at physical layer of osi model
Application Layer
Application layer.
The network layer. # Physical # Data Link # Network # Transport # Session # Presentation # Application
