树形拓扑和总线拓扑的区别

1.树拓扑：
树拓扑是一种网络拓扑，其中节点以树的设计方式排列。在树形拓扑中，分支电缆从称为根节点的头顶节点开始。没有环路的分支电缆以分层方式将根与所有其他节点连接起来进行通信。树形拓扑更昂贵，因为它是密集连线的。

2. 总线拓扑：
总线拓扑是一种网络拓扑，其中每个包含的节点都连接到作为网络主干的单根主电缆。在总线拓扑中，节点之间的通信是通过主网线完成的。由于使用一根连续电缆，因此总线拓扑的成本非常低。

树形拓扑和总线拓扑的区别如下：

S.No.	Tree Topology	Bus Topology
1.	In tree topology, the nodes are organized in the form of a tree.	In bus topology, each included node is connected to a single cable which is known as the backbone.
2.	Tree topology provides high security.	While security is very low in bus topology.
3.	Tree topology is largely complex to understand as compared to bus topology.	Bus topology is the simplest one in terms of complexity.
4.	Tree topology is also referred as hierarchical topology.	Bus topology is also known as line topology.
5.	Tree topology is expensive as it is densely wired.	Bus topology is very less expensive as one continuous cable is used.
6.	Tree topology is used for WAN.	Bus topology is generally suited for LAN as installation is easy.
