In a standard Bus Topology, what is the purpose of placing a 'terminator' at both extreme ends of the main shared backbone cable? MCQ with Answer and Explanation

In a standard Bus Topology, what is the purpose of placing a 'terminator' at both extreme ends of the main shared backbone cable?
A. To boost the electrical signal amplification.
B. To convert the network structure into a ring format.
C. To dynamically allocate IP configurations to incoming stations.
D. To absorb electrical signals and prevent signal bounce or reflection back down the line.
Answer: Option D
Solution (By JKSSB Mock Tests)
Terminators absorb signals when they reach the end of a bus line, preventing signal reflection which would otherwise corrupt ongoing data transmissions.
