In the ring topology, nodes area unit connected to every in a very control system by one communication cable. Data transfers in one direction, from one node to another around the ring. Thus, the info packets flow into on the ring in either dextrorotary or anti-clockwise direction. As a packet circulates past every station, the destination station recognizes its address on the packet header, and copies the packet contents onto itself. After a packet travels a full circle, it is removed at the source station. A ring topology is also called loop network.
In the ring topology, nodes are connected to every in a very control system by one communication cable. Knowledge transfers in one direction, from one node to a different round the ring. Thus, the information packets flow into on the ring in either right-handed or anti-clockwise direction. As a packet circulates past every station, the destination station acknowledges its address on the packet header, and copies the packet contents onto itself. once a packet travels a full circle, it’s removed at the supply station. A Roop topology is additionally referred to as loop network.
Advantages of Ring topology are:
- Transmission of knowledge is fairly easy because it solely travels in one direction.
- No knowledge collisions.
- Extra computers is additional simply with very little result on performance though you’ve got to clean up the network to be able to do that.
Disadvantages of Ring topology are:
- If one digital computer or port goes down, the whole network gets affected.
- Network is very addicted to the wire that connects totally different parts.
- Data should suffer each pc till it reaches its destination. This will build it slower than alternative network layouts.
Star topology is that the commonest topology in use these days. during a network topology, every device includes a dedicated purpose to purpose link solely to central controller “hub”. A hub could be a rectangular box-shaped device with multiple plug-in points known as ‘ports’. teams of knowledge are routed through the hub and sent to all or any the connected nodes, so eventually reaching their destinations.
Network topology refers to the physical layout of the network within which all the devices area unit connected. There area unit many forms of topographic style and methods accustomed implement LAN. Network designers think about many factors
once determinant that topology or combination of topologies to use: the sort of computers put in, type of cabling, the cost of components, distance between
each laptop and also the speed with that knowledge should travel round the network.
The ordinarily used physical network topologies area unit bus, star and ring.
