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...
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...
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...

The lowest layer of the OSI Model is concerted with electrically and optically transmitting raw unstructured data bits across the network from physical layer of the sending device to the physical layer of receiving device. It can include specifications such as voltages. pin layout, cabling and radio...
Logical addressing, the term for IP addressing done in the third layer, identifies each device uniquely on the Internet. This then allows each data packet to reach its destination. The third layer of the OSI model fulfills this via logical addresses. ...
The main aim of Network layer in OSI Reference Model is to deliver packets from source to destination across multiple links (networks). Here we have listed all the functions performed by the Network layer.
AAL lies on top of the ATM layers and corresponds to the data link layer of the OSI reference model. AAL is divided into the following layers. Convergence Sub-layer Convergence sub-layer (CS) contains the following two sub-layers: Service special convergence sub-layer (SSCS) Common part co...
