NETWORK TOPOLOGY

NETWORK TOPOLOGY

        In computer networking, topology refers to the layout of connected devices.

TYPES OF NETWORK TOPOLOGIES ARE:

·  Star topology

·  Bus topology

·  Ring topology

·  STAR TOPOLOGY: In a star topology network, the network devices are connected to a central point like a star. The central point may be a hub, a switch or router. All the individual network devices communicate with the central point.

·  BUS TOPOLOGY: Bus network topology uses a common back bone (a cable) to connect all devices. The back bone is a shared communication medium that all devices are attached or connected.

·         RING TOPOLOGY: In a ring network, all the network devices are connected together in a ring form. That is every device has exactly two neighbors for communication purposes.

·       MESH TOPOLOGY: A mesh network is a network topology in which each node relays data for the network. All mesh nodes cooperate in the distribution of data in the network. Mesh networks can relay messages using either a flooding technique or a routing technique.
