network topologies Flashcards
describe Topology
Topology is the term used to describe how devices are connected and how messages flow from device to device. There are two types of network topologies:
· The physical topology describes the physical way the network is wired.
· The logical topology describes the way in which messages are sent.
describe a star topology
A star topology uses a hub or switch to concentrate all network connections to a single physical location.
ring topology
A ring topology connects neighboring nodes until they form a ring. Signals travel in one direction around the ring. In ring topologies, each device on the network acts as a repeater to send the signal to the next device.
bus topology
Network configuration wherein all computers connect to the network via a central bus cable.
mesh topology
A mesh topology exists when there are multiple paths between any two nodes on a network.
Mesh Topologies are created using point-to-point connections. This increases the network’s fault tolerance because alternate paths can be used when one path fails.
hybrid topology
combinations of different topology
wireless topology
uses a access point to connect, can self heal if one device goes offline
