What is Network Topology? and there types.

 NETWORK TOPOLOGY :-   In the context of computer netwoks , topology refers to the arrangement of elements(links,nodes,etc.) in a network. it defines how different components of a network connected and how data is transmitted between them . network topology can have a significant impact on the performance ,reliability,and scalability of a network . several common types of network topologies exist , and each has its own advantage and disadvantages.

There are some of the main types:

1. BUS TOPOLOGY:-

           .In a bus topology all device share a single communication line (the bus).

           .Data is sent by a device and is accessible to all other devices, but only the intended                              recipient  accepts and process the data.

           .Simple and cost-effective,but can suffer from performance issue as the number of devices                     increases.

2. STAR TOPOLOGY:-

           .In a star topology, all devices are connected to a central hub or switch.

           .The central hub facilitates communication between devices.

           .Easy to install and manage, and a failure in one connection does not necessarily affect                              other  devices.

3.RING TOPOLOGY:-

          .In a ring topology, each device is connected to exactly two other devices, forming a ring.

          .Data circulates in one direction, passing through each device until it reaches its destination.

          .Relatively simple, but a failure in any single connection can disrupt the entire network.

4. MESH TOPOLOGY:-     

         .In a mesh topology, every device is connected to every other device in the network.

         .Provides high redundancy and reliability, as multiple paths exist for data transmission.

         .Complex and expensive to implement due to the large number of connections.

5.TREE TOPOLOGY:-

         .Tree topology is a combination of bus and star topologies.

         .Devices are arranged hierarchically, with the central hub connecting to other hubs or                          devices.

         .Offers scalability and can cover large areas, but the failure of the central hub can affect the                entire network.

6.HYBRID TOPOLOGY:-

       .Hybrid topology is a combination of two or more different types of topologies.

       .It aims to leverage the strengths of different topologies while minimizing their weaknesses.

       .Provides flexibility but can be complex to design and manage.

The choice of network topology depends on factors such as the size of the network, the types of devices connected, cost considerations, and the desired level of redundancy and fault tolerance. Each topology has its own trade-offs, and the selection should align with the specific requirements and goals of the network deployment.
