What is OSI? Open Systems Interconnection or OSI model was first proposed by International Standards Organization (ISO) to solve the multiple problems faced in telecommunication. It is a conceptual model of telecommunication networking where the whole process is divided into seven effective layers. It synchronizes the whole process and helps one understand the interoperation of the diverse communication system under the standard protocol. The seven layers we are talking about are abstraction layers and each layer is connected to either one or two layers depending on its position. The interlinked layers serve one another to forward the communication process. Understanding the seven layers of OSI Brief description of each of OSI Layers. Layer 1: Physical Layer: This layer is the primary layer of the OSI model and consists of connecting devi...
