数据链路(逻辑线路):在一条物理线路之上,通过一些规程或协议来控制这些数据的传输,以保证被传输数据的正确性。 网络层(network layer) 是OSI参考模型中的第三层,介于传输层和数据链路层之间,它在数据链路层提供的两个相邻端点之间的数据帧的传送功能上,进一步管理网络中的数据通信,将数据设法从源端经过若干个中间节点...
The Transport Layer delivers data across network connections.TCP(Transmission Control Protocol) andUDP(User Datagram Protocol) are the most common examples of Transport Layer 4network protocols.Different transport protocols may support a range of optional capabilities, including error recovery, flow control...
物理层规定:为传输数据所需要的物理链路建立、维持、拆除,而提供具有机械的,电子的,功能的和规范的特性。 TCP/IP协议栈 互联网协议族(英语:Internet Protocol Suite,缩写IPS)是一个网路通讯模型,以及一整个网络传输协议家族,为网际网路的基础通讯架构。它常被通称为TCP/IP协议族(TCP/IP Protocol Suite,TCP/IP Pr...

Notice that we don’t name specific programs or protocols within this model. It's meant to be completely agnostic and open, so you could use this theory on almost any kind of network. Each layer is served by the layer below it, and it provides some kind of functionality to the layer ...
This presentation will be related to the layers in the OSI Reference Model [133] in which the protocols belong, and will therefore also illustrate typical features and mechanisms in each layer. In this chapter, we shall look at the lowest four layers of the Reference Model, collectively often...
familiar with the application layer, as it's the layer they interact with most. However, if you aren’t yet familiar with the application layer and its protocols, this article breaks down all you need to know about it. Learn what the application layer is, what it does, and how it ...

interoperability and facilitate communication between different computer systems and networks. By dividing the complex task of network communication into smaller, more manageable parts, the OSI model allows for standardized protocols that can be used across various platforms and technologies.
aIn mice, a pro-inflammatory subset of monocytes induced by hyperlipidaemia may preferentially furnish the precursors of lesional foam cells, but the fates and functions of this monocyte subset and its human equivalent remain under intense exploration. 在老鼠, hyperlipidaemia导致的单核细胞的一个赞成激动...
