Homework Help: Questions and Answers: Which of the following answers refer to the characteristic features of bus topology? (Select 3 answers)
a) Each network node connects to exactly two other nodes
b) The main network cable becomes a single point of failure
c) Data is passed through each intermediate node until the receiver node is reached
d) All network nodes connect to a single central cable (a.k.a. backbone or trunk)
e) Each node becomes a network’s single point of failure
f) A terminator at each end of the main network cable prevents collisions caused by signal bounce
Answer:
First, let’s understand Bus Topology:
- In a bus topology, all devices are connected to a single central cable (backbone or trunk).
- The data sent from any device travels along the backbone and is received by all devices.
- There are terminators at both ends of the backbone to absorb signals and prevent them from reflecting back, which could cause collisions.
Let’s break down each option and determine which refer to the characteristic features of a bus topology.
Given Options: Step by Step Answering
a) Each network node connects to exactly two other nodes
- This is not a characteristic of bus topology. In a bus topology, each network node does not connect to exactly two other nodes. Instead, all nodes connect to a single central cable or backbone.
b) The main network cable becomes a single point of failure
- This is a characteristic of bus topology. The main network cable is a single point of failure, and if it is damaged or disconnected, the entire network will go down.
c) Data is passed through each intermediate node until the receiver node is reached
- This is incorrect. This describes a ring topology or possibly a mesh topology, but not a bus topology.
d) All network nodes connect to a single central cable (a.k.a. backbone or trunk)
- This is a characteristic of bus topology. All network nodes in a bus topology connect to a single central cable or backbone.
e) Each node becomes a network’s single point of failure
- This is not true for a bus topology. It describes a star topology, where if one node fails, it can bring down the network.
f) A terminator at each end of the main network cable prevents collisions caused by signal bounce:
- This is another key feature of a bus topology, where terminators prevent signals from bouncing back and causing collisions.
Final Answer:
Based on the above analysis, the correct answers are:
b) The main network cable becomes a single point of failure
d) All network nodes connect to a single central cable (a.k.a. backbone or trunk)
f) A terminator at each end of the main network cable prevents collisions caused by signal bounce
