Network Topologies
Cards in this deck (10)
- 1What is a star topology?all the devices are connected to a central switch or server that controls the network.
- 2what are the pros to a star topology?- if a device fails, it is not all affected
- simple to add more devices
- better performance than other setups - 3what are the cons to the star topology?- every device needs a cable which can be expensive
- if there is a problem with the switch, the whole network is affected - 4what is a bus topologyall devices are arranged in a line, connected to a single backbone cable. devices send data in both directions this causes data collisions which slow the network
- 5what is a ring topology?in a ring topology, data moves in one direction around the ring, preventing collisions. only one device can send data back at a time and data passes through many devices before reaching its destination
- 6what is a mesh topology?mesh topologies work by sending the data through the fastest route possible from one device to another
- 7what is the main advantage of mesh topologies?there is not one single point of failure, there is always another path
- 8what is the traditional problem of a mesh topology?they were expensive, but not anymore.
- 9what is a full mesh topology?where every device has a connection to every other device
- 10what is a partial mesh topology?where every device is connected to at least 2 other devices
