以太网如何接收位并形成数据链路层帧
我很想知道物理层的传入位如何正确构建并发送到数据链路层。 操作系统如何处理这个过程。
如果您详细解释一下或给我一些链接/pdf，我将不胜感激。
我有兴趣深入了解第 1 层和第 2 层操作。
提前谢谢。
I am curious to know how the incoming bits at the physical layer are properly framed and sent to the data link layer. How the OS deal with this process.
It would be grateful if you explained it in detail or give me some links/pdf.
I am interested to know in depth about Layer 1 and 2 operations.
Advance Thanks.

物理层取决于您的硬件。 您可能是通过以太网连接的，请参阅此处。 操作系统在这里并没有做太多事情，它主要由网卡和网卡制造商编写的设备驱动程序决定。
The physical layer depends on your hardware. You're probably connected via ethernet, see here. The operating system doesn't do a lot here, it's mostly left up to the network card and the device drivers written by the card's manufacturer.
今天的好处是，除了 Google 之外，你很少需要记住任何东西。
http://en.wikipedia.org/wiki/Ethernet
但是，问题不在于物理层实际上是电线和电线的接口； 因此物理连接。 他的问题涉及OSI 模型中的数据链路层术语。
由于以太网与 OSI 模型不匹配，并且 OSI 模型是战略模型而不是战术模型，因此在以太网术语中，您对 802.3 MAC 帧。 但由于以太网很古老，实际上有几种不同的 EtherType。
The good thing about today, is you seldom have to remember anything but Google.

However, the question is NOT about the physical layer as that is really the wires and interfaces for the wires; hence physical connections. His questions addresses the Data-Link layer in OSI Model terms.
As Ethernet Does not match the OSI model and the fact that the OSI model is a strategic rather than a tactical model, in Ethernet terms you are interested in the 802.3 MAC Frame. But then as Ethernet is old, there are actually a several of different EtherTypes.
为了共享数据，人类需要一些协议。所以这里给出了 7 层。
物理层直接与硬件连接（当脉冲以Bit格式发送时）。
它涉及接口和传输介质的机械和电气规范。
操作系统只有运行应用程序的权限，不参与任何软件。
如果您想了解详细信息，请更好地阅读信号和系统。
For sharing the data, some protocol is needed as human .so here 7 layers are given .
Physical layer direct connect with the hardware( when pulse sends in Bit format ).
It deals with mechanical and electrical specification of the interface and transmission medium.
OS have only authority to run the application not any participation in any software .
If you want detail then better read SIGNAL AND SYSTEM.
