The seven levels of the OSI (open system interconnection) reference model are

1. The first layer is the Physical Layer (i.e. the OSI model The first layer) uses the transmission medium to provide a physical connection for the data link layer to realize the transparent transmission of the bit stream. The function of the physical layer is to realize the transparent transmission of bitstream between adjacent computer nodes and shield the differences between specific transmission media and physical equipment as much as possible.

2. The seven-layer type of OSI from low to high are: physical layer, data link layer, network layer, transport layer, session layer, representation layer and application layer. Application layer: an interface between network services and end users.Representation layer: representation, security and compression of data.

3. From the first layer to the seventh layer are: physical layer, data link layer, network layer, transmission layer, session layer, representation layer, and application layer.

4. Presentation Layer: The representation method of processing communication signals, translating between different formats, and responsible for data encryption and decryption, data compression and recovery. Application Layer: Maintain the data records needed to establish connections between applications to serve users.

5. The seven levels of the OSI (Open System Interconnection) reference model are the physical layer, the data link layer, the network layer, the transmission layer, the session layer, the representation layer and the application layer. OS.The I reference model includes 7 layers, physical layer, data link layer, network layer, transport layer, session layer, representation layer and application layer.

What are the protocols for each layer of the OSI seven-layer model? Thank you!

Layer 1 Physical Layer: The physical layer transmits data frames on the local LAN, which is responsible for managing the interoperability between computer communication devices and network media. Including pins, voltage, cable specifications, hus, repeaters, network cards, host adapters, etc.

The protocol of the seven-layer model of osi: the first layer: the physical layer; the second layer: the data link layer; the third layer: the network layer; the fourth layer: the transport layer; the fifth layer: the session layer; the sixth layer: the representation layer; the seventh layer: the application layer.

The 7 layers of OSI from bottom to top are: application layer, representation layer, session layer, transport layer, network layer, data link layer and physical layer.

The seven layers of iso's OSI network model are: physical layer, data link layer, network layer, transport layer, conversation layer, representation layer, and application layer.Physical layer This layer is the basis of the entire OSI model, which is responsible for transmitting primitive bit streams on physical media (such as cables, optical fibers, etc.).

What are the protocols in the 7th layer of the OSI model?

Transport layer: The functions of this layer include whether to choose the error recovery protocol or the error-free recovery protocol, and the reuse of data flows of different applications on the same host, as well as the function of reordering the received data packets in the wrong order. Examples: TCP, UDP, SPX.

Functions and protocols of each layer of the osi seven-layer model: physical layer, data link layer, network layer, transmission layer, session layer, representation layer, application layer. Physical layer: This layer includes physical network media.It provides a physical media for transmitting data for the upper-level protocol. Common protocols include RS-23V.3RJ-4FDDI.

OSI divides the computer network architecture into the following seven layers, marked 1 to 7, and the first layer is at the bottom. The details are as follows: Layer 1 Physical Layer: The physical layer transmits data frames on the local LAN, which is responsible for managing the interoperability between computer communication equipment and network media.

The 7 layers of OSI are application layer, representation layer, session layer, transport layer, network layer, data link layer and physical layer from top to bottom. Physical layer: It is the lowest layer of the reference model. This layer is the data transmission medium of network communication, which is composed of cables and equipment connecting different nodes.

OSI layer (7 layers): physical layer, data link layer, network layer, transport layer, session layer, representation layer, application layer.TCP/IP layer (4 layers): network interface layer, network layer, transport layer, application layer. Five-layer protocol (5 layers): physical layer, data link layer, network layer, transport layer, application layer.

What are the osi seven-layer models

1. The OSI seven-layer types are from low to high in order: physical layer, data link layer, network layer, transport layer, session layer, representation layer and application layer. Application layer: an interface between network services and end users. Representation layer: representation, security and compression of data.

2. The seven levels of the OSI (Open System Interconnection) reference model are the physical layer, the data link layer, the network layer, the transmission layer, the session layer, the representation layer and the application layer.

3. The seven levels of the OSI (Open System Interconnection) reference model are physical layer, data link layer, network layer, transmission layer, session layer, representation layer and application layer. The OSI reference model includes 7 layers, physical layer, data link layer, network layer, transport layer, session layer, representation layer and application layer.

4. The OSI reference model includes 7 layers, physical layer, data link layer, network layer, transport layer, session layer, representation layer and application layer. Each function is as follows: The main function of the physical layer is to use the transmission medium to provide physical connection for the data link layer and be responsible for the physical transmission of the data stream.

5. Network Layer: mainly responsible for routing, selecting the appropriate path, blocking control and other functions. The representatives of network layer protocols include: IP, IPX, OSPF, etc.The main equipment of the network layer: router.

6. The OSI (OpenSystemInterconnection) seven-layer network model is called the open system interconnection reference model, which is a network interconnection model researched by ISO (International Organization for Standardization) in 1985. It is a Logical definition and specification.

OSI seven-layer model

Application Layer: Maintain the data records needed to establish connections between applications to serve users. The representatives of application layer protocols include: Telnet, FTP, HTTP, SNMP, etc.

Network layer: Select the appropriate path for the packet through the network, and realize routing selection and packet forwarding congestion control, etc.Transmission layer: end-to-end services provided to users, processing datagram errors, packet order, and shielding the details of lower-level data communication to the high-level.

The seven-layer type of OSI from low to high are: physical layer, data link layer, network layer, transport layer, session layer, representation layer and application layer. Application layer: an interface between network services and end users. Representation layer: representation, security and compression of data.
