The Open Systems Interconnection (OSI) model is a reference model developed by the International Organization for Standardization (ISO) that "provides a common basis for the coordination of standards development for the purpose of systems interconnection."

2025年1月20日 · The OSI (Open Systems Interconnection) Model is a set of rules that explains how different computer systems communicate over a network. OSI Model was developed by the International Organization for Standardization (ISO). The OSI Model consists of 7 layers and each layer has specific functions and responsibilities.

2024年5月22日 · The Open System Interconnection (OSI) model is a standard “reference model†created by an International Organization for Standardization (ISO) to describe how software and hardware components involved in network communication divide efforts and …

2024年9月10日 · ISO stands for International organization of Standardization. This is called a model for Open System Interconnection (OSI) and is commonly known as OSI model. The ISO-OSI model is a seven layer architecture. It defines seven layers or levels in a complete communication system. They are: Application Layer; Presentation Layer; Session Layer ...

2025年1月15日 · What Is the OSI Model? 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.

2018年7月8日 · OSI模型（Open System Interconnection Model）是一个由ISO提出得到概念模型，试图提供一个使各种不同的的计算机和网络在世界范围内实现互联的标准框架。 虽然OSI参考模型在实际中的应用意义并不是很大，但是它对于理解网络协议内部的运作很有帮助，为我们学习网 …

2018年1月24日 · OSI/RM，全称为Open Systems Interconnection Reference Model，中文名为开放系统互连参考模型，是国际标准化组织（ISO）提出的一种用于理解和设计网络通信的框架，它是网络工程师必备的核心知识。

2024年6月27日 · What is OSI Model? The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. The Open System Interconnection (OSI Model) also defines a logical network and effectively describes computer packet transfer by using various layers of protocols.

2021年3月4日 · OSI（Open System interconnect），即开放式系统互联。一般称为OSI参考模型，式ISO组织在1985年研究的网络互联模型。该体系结构标准定义了网络互联的七层价格（应用层、表示层、会话层、传输层、网络层、数据链路层、物理层），即OSI开放系统。 层次划分原则

2024年4月25日 · 国际标准化组织 (iso) 提出的网络体系结构模型称为开放系统互连参考模型(osrm).通常简称为osi参考模型。 OSI参考模型有7层， 自下而上 依次为 物理层、数据链路层、网络层传输层、会话层、表示层、应用层 。
