In this issue, the editor will bring you about what is the highest level of the OSI network protocol layer. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

The highest layer of the OSI network protocol layer is the application layer. OSI divides the computer network architecture into seven layers: 1, physical layer; 2, data link layer; 3, network layer; 4, transport layer; 5, session layer; 6, presentation layer; 7, application layer.

The highest layer of the OSI network protocol layer is the application layer.

Related introduction:

The open system interconnection communication reference model, referred to as the OSI model (OSI model), is a conceptual model proposed by the International Organization for Standardization (ISO), a standard framework that attempts to interconnect various computers into networks around the world.

The OSI/RM protocol is developed by ISO (International Organization for Standardization). It has three basic functions: to provide developers with a necessary and common concept to develop a framework that can be used to explain the connection of different systems.

OSI divides the computer network architecture (architecture) into the following seven layers:

Physical layer: converting data into electronic signals that can be transmitted through a physical medium is equivalent to a porter in a post office.

Data link layer: determines how the network media is accessed. In this layer, the data is framed and the flow control is handled. This layer specifies the topology and provides hardware addressing, which is equivalent to the packing and unpacking workers in the post office.

Network layer: the right to use data is routed through a large network equivalent to a sorting worker in a post office.

Transport layer: providing a reliable terminal-to-terminal connection is equivalent to a messenger who runs a post office in a company.

Conversation layer: allows users to establish a connection with an easy-to-remember name equivalent to the secretary in the company who receives and sends letters, writes envelopes, and opens envelopes.

Presentation layer: the negotiation data exchange format is equivalent to the presentation boss and the assistant who writes for the boss in the company.

Application layer: the interface between the user's application and the network.

The above is what the editor shares with you what is the highest level of the OSI network protocol layer.
