Question

What is the reason for the disruption of normal communication system?

• A. Breakage of cable
• B. Damage to transmission tower
• C. Disruption of power supply
• D. All of these

Hint:

During major disasters, "All of these" factors often fail simultaneously, which is why satellite phones and HAM radio are used as emergency backups since they are less dependent on local infrastructure.

Answer 1

The Correct Option is D

To understand the disruption of normal communication systems, we need to consider possible causes and how each of them affects the system:

1. Breakage of cable: Communication systems often rely on cables, such as fiber optic or coaxial cables, to transmit data. If these cables are broken, it can lead to a complete or partial loss of signal transmission, resulting in disruption.
2. Damage to transmission tower: Transmission towers are critical for broadcasting signals over long distances. Any damage to these towers, whether due to natural disasters or technical failures, can disrupt the signal propagation, affecting communication networks.
3. Disruption of power supply: Communication systems need a continuous power supply to operate. A power disruption can halt the functioning of essential equipment in data centers, switching stations, and network operation centers, leading to a breakdown in communication.

Given these points, all the factors listed can independently cause disruptions to communication systems. Therefore, the correct answer is:

All of these

• The breakage of cable, damage to transmission towers, and disruption of power supply are common causes of communication breakdowns.
• Choosing the option "All of these" is logical as it encapsulates all possible scenarios that can affect communication systems negatively.
