先决条件 – 网络拓扑类型

1. 环形拓扑:
在环形拓扑中,存在环形数据路径。每个设备都连接到网络中的另外两个设备。数据从发送方传输到接收方,通过将数据从一个设备传递到另一个设备,直到到达接收方设备。如果有任何连接坏了然后整个网络崩溃,因为它们是顺序连接的。这种拓扑结构主要用于连接局域网或广域网。

2. 总线拓扑:
总线拓扑是一种网络拓扑,其中所有设备都连接在一根电缆上,称为网络的骨干。它在电缆的每一端都有一个终结器。网线负责之间的通信设备,当数据到达电缆末端时,它会被数据线的终结器移除。当设备以线性方式连接时,这是最简单的网络拓扑。

环形拓扑和总线拓扑的区别:

S.NO. Ring Topology Bus Topology
1. In Ring topology each device is connected to two other devices in a circular fashion. Bus topology is a topology where each device is connected to a single cable which is known as the backbone.
2. In Ring topology data is sent through the devices from sender to receiver device.. In Bus topology data is sent directly from sender to receiver device..
3. Ring topology has lower implementation cost than bus topology. The implementation cost of Bus topology is higher than Ring topology
4. Ring topology is less reliable as failure of one device affects whole network. Bus topology is more reliable than Ring topology
5. Tracking fault is easy in Ring topology than Bus topology. It is difficult to find fault in Bus topology.
6. Addition of new device is difficult in Ring topology than Bus topology. In Bus topology new device is added very easily.
7. The access speed is less than Bus topology because of sequential access. Access speed is fast in comparison of Ring topology
8. Ring topology do not contains any terminators. Bus topology has terminators at both ends.
