• 1.
  TOPOLOGY • Topology meansthe physical structure of the network. • Topology refer to the way in which the network of the computer is connected. • Network topology is the arrangement of different host machines in a network. • Star, ring, bus, tree, complete, irregular, hybrid are the types of network topologies.
• 2.
  STAR TOPOLOGY • Astar topology, the most common network topology, in which every node in the network is directly connected to the central hub via coaxial cable, twisted pair or fiber optic cable. • Devices can only communicate with each other indirectly through the central hub. • Acting as a server, this central node manages data transmission –as information Sent from the any node on the network has to pass through the central one to reach its destination. • The Hub in a star network can be either active or passive.
• 3.
  BUS TOPOLOGY • Bustopology is a network type in which every computer and network device is connected to a single cable. • It transmits the data from one end to another in a single direction. • No bi-directional feature is in bus Topoloy. • When a node wants to send a message over the network.it puts a message over the network. • All the stations available in the network Will receive the message whether it has been addressed or not.
• 4.
  RING TOPOLOGY • Ringtopology is when nodes are arranged in a circle. • The data can travel through the ring network in either one direction or both directions with each device having exactly two neighbors. • Ring topology is like a bus topology,but with connected ends. • The node that receive the message from the previous computer will retransmit to the next node . • The data flows in one direction . • The data flows in a single loop continuously known as endless loop. • It has no terminated ends. • The data in a ring topology flow in a clock wise direction.
• 5.
  TREE TOPOLOGY • Thetree topology combines the characteristics of bus topology and star topology. • A tree topology is a type of structure in which all the computers are connected with each other in hierarchical fashion. • The top most node in tree topology is known as a root node. And All other nodes are the descendants of the root node. • There is only one path exist between two nodes for the data transmission.thus,it forms a parent-child hierarchy. • Tree topology has at least three level of hierarchy. • Tree topology is applied in wide area network.
• 6.
  COMPLETE TOPOLOGY/MESH TOPOLOGY •Complete topology is also known as mesh topology. • Mesh topology is an arrangement of the network in which computers are interconnected with each other through various redundant connections. • There are multiple paths from one computer to another computer. • It does not contain switch, hub or any central computer which acts as a central point of communication. • Mesh topology is point to point connection. • Mesh topology has two techniques for transmission of data routing and flooding.
• 7.
  IRREGULAR TOPOLOGY • Irregulartopology means to connect the node or computer in any arbitrary fashion is called irregular topology. • In irregular, devices are connected with each other irregularly in the network. • Irregular topology means which is not in graph structure. • It has no fix structure. • Irregular topology are used in larger WAN and in internets.
• 8.
  HYBRID TOPOLOGY • Thecombination of various different topologies is known as hybrid topology. • A hybrid topology is a connection between different links and nodes to transfer the data. • When two or more different topologies are combined together is termed as hybrid topology and if similar topologies are connected with each other will not result in hybrid topology. • For example,if there exists a ring topology in one branch of ICICI Bank and bus topology in another branch of ICICI Bank, connecting these two topologies will result in hybrid topology.
