    isoabbr.

    1.=International Standards Organization.

    OSI is an abbreviation for Open System Interconnect.

    Cisco's Internet Operating System (iOS) is a complex operating system optimized for interconnects—similar to a Local Area Operating System (NOS), such as Novell's Netware, optimized for LANS. iOS provides a single set of rules for cost-effectively maintaining an Internet network over a long period of time. In short, it is a software architecture that is decoupled from hardware and can be dynamically upgraded to adapt to changing technologies (hardware and software) as network technology continues to evolve.

    iOS can be thought of as an interconnected hub: a highly intelligent administrator who manages the functions of controlling complex distributed network resources.

    First, the reference is different.

    1. ISO: The International Organization for Standardization (ISO) is a global non-leading organization and a very important organization in the field of international standardization.

    2. OSI: The Open Source Organization is a non-profit organization dedicated to promoting the development of open source software.

    Second, the content of the work is different.

    1. ISO: Responsible for standardization activities in most fields (including monopoly industries such as military industry, petroleum, and shipbuilding). ISO currently has 117 members, including 117 countries and regions.

    The supreme authority of the ISO is the annual "General Assembly", and its day-to-day office is the ** Secretariat, located in Geneva, Switzerland.

    2. OSI: Manage the definition of open source and review terms, as long as the terms are approved and are in line with the definition of open source, it can be called open source license terms, and the software that uses open source terms to distribute the license is open source software.

    Third, the role is different.

    1. ISO: It is the world's largest non-national standardization agency and a very important organization in the field of international standardization.

    2. OSI: When the software is one of the components of a software distribution after the integration of several different programs, the license cannot restrict the sale or distribution of the software by any group, and license fees and other fees cannot be charged for such sales or distribution.

    Hello, OSI (Open System Interconnect), that is, open system interconnect. Generally known as the OSI reference model, it is a network interconnection model studied by the ISO (International Organization for Standardization) organization in 1985. This architecture standard defines a seven-layer framework for network interconnection (physical, data link, network, transport, session, presentation, and application layers) for network interconnection, known as the ISO Open Systems Interconnection Reference Model.

    The functions of each layer are further defined in detail under this framework to enable interconnectivity, interoperability, and application portability in an open systems environment.

    Features: (1) Each node in the network has the same level;

    2) The same layer of different nodes has the same function;

    3) Adjacent layers in the same node communicate through interfaces;

    4) each layer uses the services provided by the lower layer and provides services to its upper layer;

    5) The same layer of different nodes realizes the communication between the peer layer according to the protocol.

    osi(open

    system

    interconnection, open systems interconnection) seven-layer network model is called the open systems interconnection reference model.

    is a logical definition, a specification, which logically divides the network into 7 layers. Each layer has related and corresponding physical devices, such as routers and switches. osi

    The seven-layer model is a framework design approach.

    The main purpose of the seven-layer model is to solve the compatibility problems encountered in the interconnection of heterogeneous networks, and its main function is to help different types of hosts achieve data transmission. Its greatest advantage is that it clearly distinguishes the three concepts of service, interface and protocol, and enables reliable communication between different systems and different networks through seven hierarchical structural models.

    Presentation layer: The format of the data, and the encryption of the data.

    Session layer: Establish connections and manage sessions for different applications.

    The above three layers define how applications in the end system will communicate with each other and with users.

    Transport layer: Provides reliable or unreliable transmission.

    Flow control at this layer prevents the sending host on one side of the connection from overflowing the buffer of the receiving host on the other side--- which can result in data loss.

    Window mechanism: The window is used to control the number base of unconfirmed data segments.

    Network Layer: Provides logical addressing for routing by the router.

    Data Link Layer: Packets are combined into bytes and bytes are combined into frames, MAC addresses are used to provide access to media, and error detection is performed but not corrected.

    Physical layer: Transmits bitstreams between devices, specifying the voltage size, line speed, and pins of the cable.

    The following 4 layers define how end-to-end data transfer takes place.

    I hope it helps you, that's pretty much it, it's useless to understand this if you don't learn the Internet.

    This is a reference model that describes the communication situation of a computer network. Rent first knows what needs to be done when a piece of data is sent from one computer to another. For non-specialists, there is no need to delve into the specific content of the disadvantages.
