What is Topology  Network Topology is the arrangement of the various elements links, nodes, etc. of a computer network. it is the topological structure of a network and may be depicted physically or logically. Topologies are divided into two types. One is called physical topology & another one is logical topology. Physical topology is the placement of the various components of a network, including device location and cable installation, while logical topology illustrates how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two networks.   Topology There are a number of reasons to understand about Topology: The network topology impacts performance The network topology is a factor in determining the media type used to  cable the network The networking topology impacts the cost of cabling the network. Some access m...

  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...
