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.

开放式系统互联模型（英語： Open Systems Interconnection Model ，縮寫：OSI；簡稱為OSI模型）是一種概念模型，由国际标准化组织提出，一个试图使各种计算机在世界范围内互连为网络的标准框架。定義於ISO/IEC 7498-1。

2025年1月15日 · 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.

2020年12月21日 · This article explains the Open Systems Interconnection (OSI) model and the 7 layers of networking, in plain English. The OSI model is a conceptual framework that is used to describe how a network functions. In plain English, the OSI model helped standardize the way computer systems send information to each other.

2024年6月11日 · What is the OSI model? The Open Systems Interconnection (OSI) model—also called the OSI reference model—is a conceptual model that divides network communication and interoperability into seven abstract layers. It provides a standardized model that enables different applications, computer systems and networks to communicate.

The Open Systems Interconnection (OSI) model is a conceptual framework that divides network communications functions into seven layers. Sending data over a network is complex because various hardware and software technologies must work cohesively across geographical and political boundaries.

2024年6月27日 · 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.

1 天前 · OSI/RM（Open System Interconnection/Reference Model）是一个标准化的七层网络体系结构模型，用于定义和规范不同系统间的信息交换。该模型从下到上依次为物理层、数据链路层、网络层、传输层、会话层、表示层和应用层。其中低三层关注端到端的数据传输，涉及硬件设备间的通信连接建立与管理；高三层 ...

The Open Systems Interconnection (OSI) model describes how computer systems communicate across networks. Published by the International Organization for Standardization (ISO) in 1984, it divides communications into seven layers, providing …
