星形和网状拓扑之间的区别

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，其中信息从节点传输到节点。

网状拓扑：
在Mesh拓扑中，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播，如果有N个节点，Mesh拓扑中有N(N-1)/2条链路。

星型拓扑和网状拓扑的区别：

S.NO	Star Topology	Mesh Topology
1.	In star topology, the nodes are connected to the central hub or router.	In mesh topology, the nodes are connected to each other completely via dedicated link.
2.	There are N links in Star topology, if there are N nodes.	There are N(N-1)/2 links in Mesh topology, if there are N nodes.
3.	The cost of Star topology is less.	The cost of Mesh topology is expensive.
4.	The complexity of Star topology is quite simple.	The complexity of Mesh topology is complex.
5.	In star topology, the information is travel from central hub or router to all the nodes.	In mesh topology, the information is travel from nodes to nodes.
6.	Star topology is very good extensible.	Mesh topology is poor extensible.
7.	In star topology, twisted pair cable is used for connection.	In mesh topology, twisted pair cable, coaxial cable and optical fiber cable are used for connection on the basis of type of networks.
8.	Star topology is used in LAN as setup is easy.	Mesh topology is used in WAN.
