Physical Layer in OSI Model in Networking
Physical Layer in OSI Model- The physical layer is the first layer of the Open Systems Interconnection (OSI) Model depending on which end you decide to start your counting. It holds a significant role in the functioning of the OSI Model. As suggested by the name, it has a physical body that consists of circuits and technologies of the network. To know more about the Physical Layer in the OSI Model, keep reading this article till the end.
Most of the time, the physical layer is installed in the form of a chip. This chip is called PHY (Chip), an abbreviation for 'Physical Layer’.
The role assigned to the Physical Layer is to deal with the physical connectivity of two different stations with interacting with hardware and mechanism of the signal, making it the only layer to be capable of doing so.
All the Layers in the model work on the data or functions provided by the lower layer and provides its’ services to the layer above itself. Being the lower-most layer, the physical layer only provides the service to the data link layer in the form of raw bits or electrical pulses instead of data packages like some of the other layers.
The electrical pulses are representative of the binary data that can be sent over both the wireless and the wired network and media.
Despite being named the physical layer, it does not deal with the actual physical mediums such as fiber and copper
