The most popular packet-based structure of layers, or protocol stack, is called the OSI model (Open System Interconnection), which was created, oddly enough by the reverse acronym, the ISO (International Organization for Standardization). It defines 7 layers. The user interface (Application Layer...
Network Layers Diagram 2 TCP/IP 2.1 TCP—传输层 传输控制协议(英语:Transmission Control Protocol,缩写:TCP)是一种面向连接的、可靠的、基于字节流的传输层通信协议,由IETF的RFC 793定义。在简化的计算机网络OSI模型中,它完成第四层传输层所指定的功能。用户数据报协议(UDP)是同一层内另一个重要的传输协议[3]...
What is OSI Model: A Complete Guide to The 7 Layers of the OSI Model In thisFree Networking Training Series, we explored all aboutComputer Networking Basicsin detail. OSI Reference Model stands forOpen system interconnection reference modelwhich is used for communication in various networks. The I...
I'll reference both models when discussing the various layers. The following diagram compares the OSI and DARPA reference models: Unless you're in the business of writing protocols, there's no need to study any of the seven layers in great depth, but it is helpful to understand them ...
The followingdiagram illustrates this process. OSI's seven layers use a variety of controlinformation to communicate with the corresponding layers of other computersystems. These control information contain special requests and instructionsthat are exchanged between the corresponding OSI layers. The head ...
Many devices operate at multiple (or even all) layers of the OSI model. For example, your laptop may have apps running at Layer 7 and a network interface card (NIC) transmitting the ones and zeros at layer 1. Just like the first point, don't let this nuance confuse you, focus on th...
The following diagram illustrates this process. OSIs seven layers use a variety of control information to communicate with the corresponding layers of other computer systems. These control information contain special requests and instructions that are exchanged between the corresponding OSI layers. The ...
