星形和环形拓扑之间的区别

先决条件 – 网络拓扑
星形拓扑：
在星型拓扑中，节点连接到中央集线器或路由器，其中信息从中央集线器或路由器传播到所有节点。如果有n个节点，则星型拓扑中有n条链路。节点之间完全通过专用链路相互连接，其中信息从节点到节点传输。新电缆添加到中央集线器以在星形拓扑中添加新节点。

环形拓扑：
在环形拓扑中，每个节点都连接到它的左侧和右侧节点，其中信息在一个方向上以环形方式从节点传播到节点。如果存在 n 个节点，则在星形拓扑中也有 n 个链接.在环形拓扑中，要添加新节点，必须断开整个连接。

星形和环形拓扑的区别：

S.NO	Star topology	Ring Topology
1.	In star topology, the nodes are connected to the central hub or router.	In ring topology, every node is connected to it’s left and right side nodes.
2.	In star topology, only hub is failure point.	In ring topology, every nodes are failure point.
3.	The cost of star topology is high.	The cost of ring topology is low.
4.	In star topology, the information is travel from central hub or router to all the nodes.	In ring topology, the information is travel from nodes to nodes in ring manner in one direction.
5.	The cables are required in star topology more than the ring topology.	The cables are required in ring topology less than the star topology.
6.	There are n links in Star topology, if there are n nodes.	There are also n links in ring topology, if there are n nodes present.
7.	A new cable is added to the central hub to add a new node.	Whereas to add a new node in ring topology, the connection must be broken.
8.	In Star topology, addition and removal of new nodes is moderately difficult.	In ring topology, addition and removal of new nodes is difficult.
