How Ethernet receives bits and frames a data line

I am curious to know how the incoming bits in the physical layer are correctly generated and sent to the data link layer. How the OS handles this process.

It would be appreciated if you could explain this in detail or give me links / pdf.

I am interested to know in detail about the operations of level 1 and 2.

Thank you.

The physical layer depends on your hardware. You are probably connected via ethernet, see here . The operating system is not much here, it mostly stayed before the network card and device drivers written by the card manufacturer.

The good thing is that today you rarely have to remember anything other than Google. http://en.wikipedia.org/wiki/Ethernet

However, the question is not about the physical layer, since these are indeed wires and interfaces for wires; hence the physical connections. His questions are about the Data-Link layer in terms of the OSI model .



How Ethernet Doesn't match the OSI model and the fact that the OSI model is a strategic and not a tactical model, in Ethernet terms you are interested in 802.3 MAC frame . But then, when Ethernet was obsolete, there actually are several different EtherTypes .

To exchange data, you need some kind of protocol as a person. There are also 7 levels here. The physical layer is directly connected to the hardware (when the pulse is sent in bit format). It deals with the mechanical and electrical characteristics of the interface and transmission media. The OS only has the authority to run the application, not to participate in any software. If you want more details, then it is better to read SIGNAL AND SYSTEM.
