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...
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...
第1层 物理层(Physical Layer)是计算机网络OSI模型中最低的一层。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。
The Application Layer serves as the interface between the end-user applications and the underlying network services. This layer provides protocols and services that are directly utilized by end-user applications to communicate across the network. Key functionalities of the Application Layer include resourc...
The application layer is the closest layer to the end user. It receives information from the end user and sends results back to the user. Despite its name, Layer 7 is not where client applications live. This layer provides the protocols that allow software/apps to transmit data, including: ...
The Open Systems Interconnection (OSI) model defines a networking framework to implement protocols in layers, with control passed from one layer to the next. It is primarily used today ... 查看原文 网络七层协议 网络七层协议OSI/RM(OpenSystemInterconnectionReferenceModel)即开放系统互联基本参考模型TCP...
The Open Systems Interconnection (OSI) model defines a networking framework to implement protocols in layers, with control passed from one layer to the next. It is primarily used today as a teaching tool. It conceptually divides computer network architecture into 7 layers in a logical progression....

Logical link control (LLC) layer – responsible for identifying and encapsulating network layer protocols, and controls error checking and frame synchronization. 数据链路层提供节点到节点的数据传输--两个直接连接的节点之间的链接。它检测并可能纠正在物理层可能发生的错误。
Dive deep into the OSI Model to understand its seven layers, their functions, and how it defines the networking framework to implement protocols in seven layers.
