The Open Systems Interconnection (OSI) model of networking is the framework that governs communication between different devices on a network. It is a hierarchical model with seven different layers, each of which has a specific function in the network communication process. 1. Physical Layer The first and most basic layer of the OSI model is … Read more
Multiprotocol Label Switching (MPLS) is a game-changing technology that has revolutionized the way we think about network connectivity. It has become increasingly popular in recent years, particularly in the business world, where it provides a more efficient, cost-effective, and reliable way to connect different networks. MPLS is a protocol that is used to manage traffic … Read more
The Open Systems Interconnection (OSI) model diagram is a framework developed by the International Organization for Standardization (ISO) to standardize communication between different computer systems across the world. The OSI model is a layered approach that defines seven different layers, each with its unique functions in network communication. The OSI model diagram illustrated is essential … Read more
