1. The following about the star network is true (assuming the clusters equipment used is the hub) ()
A, once A hub fails, the entire network will collapse
B, if there is a fractured network media, the entire network does not work
C, because the network is the only clusters located in hub, so the star topology is easy to maintain
D, the star network eliminates the end user of the center system dependency

The answer to A


Question: answer C is right?

2. The transmission delay, determine the network topology is (),

A) mesh topology

B) the tree topology

C) ring topology

D) a star topology

Help to solve and analyze

CodePudding user response:

First, easy to maintain the star topology is known, is often see can determine is right, but check the subject when please note half sentence: because the network of only clusters located in hub,

Second, the advantage of ring topology is simple in structure, implementation is easy, transmission delay, adapt to lose the heavier load, high real-time requirements of application environment, so choose C,
