Functions of Different Layers in OSI ModelFollowing 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.1. The Physical LayerPhysical Layer is the lowest layer of the OSI Model. It activates, ...
" 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.
The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. The OSI model is divided into seven distinct layers, each with specific responsibilities, ranging from physical hardware connections to high-level application interactions. Each la...
表示层是OSI模型中功能最简单的一层。它处理消息数据的语法格式,例如格式转换以及支持应用层的加密和解密操作。 应用层 应用层提供网络服务给端用户的应用。网络服务通常是用户数据一起使用的协议。例如web浏览器应用,应用层协议HTTP打包发送和接受页面所需要的数据。第七层想表示层提供数据(并从中获取数据)。
The OSI reference model has 7 layers. The principles that were applied to arrive at the seven layers can be briefly summarized as follows: OSI参考模型具有7层。 可以概括为以下七个层而应用的原理: A layer should be created where a different abstraction is needed. ...

OSI模型的全称是Open Systems Interconnection model,意为开放式系统互联模型,20世纪80年代它作为第一个网络通信标准被所有主要计算机和通信公司所采用,共有七个不同作用的应用层组成。虽然现在的Internet并不是基于OSI模型,而是使用更简单的TCP/IP模型。但是,OSI七层模型仍然被广泛使用着,目前它发挥着可视化、帮助人们理...
OSI网络结构的七层模型 (OSI Network Architecture 7 Layers Model) 开放式系统互联模型(OSI)是1984年由国际标准化组织(ISO)提出的一个参考模 型。作为一个概念性框架,它是不同制造商的设备和应用软件在网络中进行通信的标准。...
