All nodes are dependent on a central node.
The wiring cost is less for large installations.
Failure of the central node will crash the network.

Option 3 : The wiring cost is less for large installations.

Star Topology in PLC connection:

In a star topology, each device is connected by a point-to-point link to a central hub that acts as the single switching device.
The communication processing load is on that central hub. When a device wants to transmit data, it first sends a request to the central hub asking for a connection to a specific destination.
Once the link is set by the central hub, data is exchanged between the two devices as if they were connected on a point-to-point link.
All nodes are dependent on the central node, hence failure of the central node will crash the network.
The wiring cost of star topology is very large for a large installation.

In the following question, the 1st and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/ passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since. S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
