WELCOME

INTRODUCTION TO NETWORK : Network is a communication system which support many users. A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.

NETWORK TOPOLOGY : Network topology refers to the physical or logical layout of a network. It defines the way different nodes are placed and interconnected with each other. Alternately, network topology may describe how the data is transferred between these nodes.

TYPES OF NETWORK TOPOLOGY : 1. Star topology 2. Bus topology 3. Ring topology 4. Mesh topology 5. Tree topology 6. Hybrid topology

STAR TOPOLOGY : A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point , like a hub or a switch. All cables run to a central connection point. If one cable breaks or fails, only the computer that is connected to that cable is unable to use the network. A star topology is scalable.

BUS TOPOLOGY : A bus topology is a topology for a Local Area Network (LAN) in which all the nodes are connected to a single cable. The cable to which the nodes connect is called a "backbone". If the backbone is broken, the entire segment fails. The bus topology is e. g. used by Ethernet networks. Bus topology was used for early 10 Base -2, Thin. Net, and 10 Base-5, Thick. Net, coaxial cable Ethernet networks.

RING TOPOLOGY : A ring topology is a network configuration in which device connections create a circular data path. Each networked device is connected to two others, like points on a circle. Most ring topologies allow packets to travel only in one direction, called a unidirectional ring network. The ring is used in both directions to have two distinctive paths to the public switch.

MESH TOPOLOGY : A mesh network is a local network topology in which the infrastructure nodes connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from clients. Mesh topology, some nodes are connected to all the others, but others are only connected to those nodes with which they exchange the most data.

TREE TOPOLOGY : A tree topology is a special type of structure in which many connected elements are arranged like the branches of a tree. Tree topologies are frequently used to organize the computers in a corporate network, or the information in a database. A tree network, or star-bus network, is a hybrid network topology in which star networks are interconnected via bus networks. Tree networks are hierarchical, and each node can have an arbitrary number of child nodes.

HYBRID TOPOLOGY : A hybrid topology is a type of network topology that uses two or more differing network topologies. These topologies include a mix of bus topology, mesh topology, ring topology, star topology, and tree topology. Star-‐Ring and Star-‐Bus networks are most common examples of hybrid network.
