The data link layer has the responsibility of moving frames from one node to the other node. Data Link Layer: The Data Link layer is the second layer above the model’s Physical layer.After converting it, send data to the Data-link layer. Whatever data comes to this layer is converted in binary format, i.e. This layer is actually responsible for the connection between two devices. The physical layer works for the sending of individual bits from one node to another node. Physical Layer: The Physical layer is the first layer of the OSI Model.The transport layer is the Heart of the OSI Model. Physical, data link and network layers are the hardware layers of this model and Session, presentation, and application are the software layers of the Model. These two computers are trying to communicate with each other over the network. Understanding the OSI Model: The Open Systems Interconnection (OSI) model is divided into seven layers, as shown in the below diagram:Įxplain in brief: 7 layers of the OSI Model.OSI Model Definition: the Open Systems Interconnection (OSI) model is the virtual model that describes the Concept of a computer system with internal structure and technology.Web development, programming languages, Software testing & others Start Your Free Software Development Course
