Network layer in osi model javatpoint. OSI consists of seven layers, and each layer performs a particular network function. The layers manage the physical transfer of data from one device to another. Developed by the International Organization for Standardization (ISO), the OSI model divides the communication process into seven distinct layers. After reading this tutorial, you will be able to understand why the network layer is used in computer networks, how it works on the network, and what are the responsibilities of the network layer. Mar 26, 2025 · This tutorial explains the OSI reference model. The physical layer, data link layer, and network layer are the network support layers. It offers routes for data packet transfers across the network. OSI model was developed by the International Organization for Standardization (ISO) in 1984, and it is now considered as an architectural model for the inter-computer communications. The network layer is also responsible for organizing and controlling the available paths for data transfer. Jul 23, 2025 · OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement network communication protocols. Contents: Jun 27, 2024 · In the below-given diagram, you can see that the data link layer of the first system communicates with two layers, the network layer and the physical layer of the system. . The tutorial covers topics like network architecture and components, different network types and topologies, transmission modes, networking models like OSI and TCP/IP, and physical and logical layers. Jul 30, 2025 · Data is transmitted in the form of packets via various logical network pathways between various devices. In this tutorial, you will learn the basic concepts of the network layer in OSI Model. It is designed for beginners and professionals to learn about computer networks. Nov 23, 2021 · Explore the layers of the OSI model in computer networks, understanding their functions and significance in networking. Learn the seven layers of the OSI model and the functions of each layer in detail through examples. Each layer has specific functions, ranging from the Physical Layer, which handles the transmission of raw bits, to the Application Layer, which provides network services to end-users. lqove l4fiv1i qohmerrv rfgjkqo kf7 kb6w5bv 2qgn cnlnq x1q 3avuh
