不同层的功能(Functions of Different Layers) Following are the functions performed by each layer of the OSI model. This is just an introduction, we will cover each layer in details in the coming tutorials. 以下是OSI模型的每一层执行的功能。 这只是一个介绍,我们将在接下来的教程中详细介绍每一层...
" 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.
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…
OSI layers 1, 2 are combined into one Network Access Layer in TCP/IP – however TCP/IP does not take responsibility for sequencing and acknowledgement functions, leaving these to the underlying transport layer. Other important differences: TCP/IP is a functional model designed to solve specific c...
c. the first three layers OSI模型包含七层:物理层(第1层)、数据链路层(第2层)、网络层(第3层)、传输层(第4层)、会话层(第5层)、表示层(第6层)和应用层(第7层)。路由器的主要功能是转发基于IP地址的数据包,而IP地址属于网络层(第3层)。 1. **选项a(所有层)**:错误。路由器仅处理前三层(物...
This tutorial explains the OSI reference model. Learn the seven layers of the OSI model and the functions of each layer in detail through examples. The OSI (Open System Interconnection) reference model is a comprehensive set of standards and rules for hardware manufacturers and software developers....
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...
OSI Model Overview—This section reviews the OSI model. Communicating Between Layers—This section describes encapsulation and de-encapsulation. Written Exercise 1—This section has a written exercise to test the students’ knowledge of the OSI model. Physical Layer Functions—This section describes the...
OSI Model https://www.imperva.com/learn/application-security/osi-model/ What Is the OSI Model The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. It was the first standard model for network communications, adopted by all ...
The Open System Interconnect (OSI) model in computer networking has seven layers, each of which is assigned a set of functions. Layer 5, or the session layer, is essential in initiating requests and responses of dialogue within systems. The model helps establish, manage, and terminate ...
