The OSI model has 7 layers, each of which can have several sub layers. Heres a brief introduction to these 7 layers and their functions. The 7 layers of OSI are from top to bottom 7 application layer 6 presentation layer 5 session layer 4 transport layer 3 network layer 2 data link ...
Core Functions of the OSI Model The OSI Model operates by allowing each of its seven layers to perform specific functions while relying on the services provided by the layer immediately below it. When data is transmitted from one device to another, it passes through all seven layers at the...
" you've heard about the OSI layer model. The terms are a bit technical, and students often struggle to remember them. But dig in, and you'll discover that the layers are both economical and elegant.
Windows 网络驱动程序 实现OSI 模型的底层四层。物理层物理层是 OSI 模型的最低层。 此层管理非结构化原始位流通过物理介质的接收和传输。 它描述了与物理介质的电气/光学、机械和功能接口。 物理层承载所有较高层的信号。在Windows 中,网络接口卡 (NIC) 实现物理层、其收发器和 NIC 连接到的介质。
OSI模型的数据链路层(Data Link Layer)(即第2层)负责为数据包添加头和尾,为数据包可以转换为适合于局域网和广域网线路传输的二进制格式做准备。第2层可以分为两个功能子层,上子层是逻辑链路控制(Logical Link Control,LLC)子层,并在IEEE 802.2规范中定义,它与数据链路层之上的网络层(NetworkLayer)通信。LLC...
文章首发 原文地址 开发式系统通信互联(OSI)模型开发式系统通信互联(OSI)模型定义了一种实现了在层之间实现网络协议,并且控制一层传递到下一层的网络架构。当今它最主要的用途就是作为教学工具。它在概念上将…
The model is often used when discussing the different parts of a communication system, such as a computer network. In other words, it is used to describe the data communication process in a network. What are the functions of the 7 layers of the OSI model? The physical layer sends...
