Model Layer. Ans There are 7 layers of the OSI Model Physical Layer Data Link Layer Network Layer Transport Layer Session Layer Presentation Layer Application Layer.
Models and layers Creating models with the Layers API There are two ways to create a model using the Layers API A sequential model and Validation Both the sequential model and the functional model are instances of the LayersModel class One of the major Model summary Name and type of all.

Physical Layer The physical layer is responsible for the physical cable or wireless connection between network nodes It defines the connector the electrical cable or wireless technology connecting the devices and is responsible for transmission of the raw data which is simply a series of 0s and 1s while taking care of bit rate control Data Link Layer The data link layer establishes and terminates a connection between two physicallyconnected nodes on a network It breaks up packets into frames and sends them from source to destination Network Layer The network layer has two main functions One is breaking up segments into network packets and reassembling the packets on the receiving end Transport Layer The transport layer takes data transferred in the session layer and breaks it into “segments” on the transmitting end It is responsible for reassembling the segments on the receiving end turning it back into data that can be used by the session layer.
What is the OSI Model? 7 layers of OSI Model Explained
Layer 1 is the physical layer There’s a lot of technology in Layer 1 everything from physical network devices cabling to how the cables hook up to the devices Layer 2 is the data link layer Layer 2 defines how data is formatted for transmission how much data can flow between nodes for how long and what to do when errors are detected in this flow Layer 3 is the network layer This is where we send information between and across networks through the use of routers Instead of just nodetonode communication we can now do networktonetwork communication Layer 4 is the transport layer This where we dive into the nitty gritty specifics of the connection between two nodes and how information is transmitted between them.

Physical Layer (Layer 1) The lowest layer of the OSI reference model is the physical layer It is responsible for the actual physical connection between the devices Data Link Layer (DLL) (Layer 2) The data link layer is responsible for the nodetonode delivery of the message The main function of this layer is to make sure data transfer is errorfree from one node to another over the physical layer Network Layer (Layer 3) The network layer works for the transmission of data from one host to the other located in different networks It also takes care of packet routing ie Transport Layer (Layer 4) The transport layer provides services to the application layer and takes services from the network layer The data in the transport layer is referred to as Segments.
