The physical layer, like other layers of the OSI model, is designed to perform a specific task. All of the layers work together to perform the overall function of the model and process. In this case, its main task is to transmit data across a connection, which requires electrical, mechanic...
业内借鉴计算机网络通信体系架构的OSI模型(Open System Interconnection Reference Model,即开放式系统互联通信参考模型),将区块链逻辑架构划分为三层——Layer0、Layer1和Layer2。 1) Layer0:对应OSI模型的底层协议,大致包括物理层、数据链路层、网络层和传输层。 2) Layer 1:大致包括数据层、共识层和激励层。我们所...
OSI Layer 1 - Physical Layer In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer. The implementation of this layer is often termed PHY. The physical layer consists of the basic networking hardware transmission technologies of a netwo...
