Data Link Layer of OSI Model The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and standardize the functions of a telecommunication or computing system. It divides the communication process into seven distinct layers, each responsible for specific tasks. The Data Link Layer handles the packaging and delivery of data between devices connected on the same network. In this blog post, we'll look into the Data Link Layer, the second layer of the OSI model, and explore its functions in network communication.

All About Network Protocols A set of rules, and data formats that define how devices communicate on a network is called a network protocol. In fact, without all these protocols, computer networks would not exist. Network protocols divide communication mechanisms into separate tasks at each layer of the OSI model. Each communication layer uses one or more network protocols. These are just a few examples of popular network protocols that play essential roles in enabling communication and data transfer across various types of networks.
