What is the transmission flaw defined as the loss of a signal's strength as it travels away from its source?

• A. Attenuation
• B. Latency
• C. Jitter
• D. Reflection

Answer: (A)

Attenuation is the loss of signal strength as it travels away from the source. In networks, signals weaken due to spreading, absorption, and scattering as they move through cables, fiber, or air. The farther the signal travels, the weaker it becomes unless equipment like repeaters or amplifiers is used to boost it, which is why attenuation is a central concept in determining usable link distance and necessary amplification. Latency refers to how long it takes for a signal to reach its destination, jitter is the variability in that arrival time, and reflection is when part of the signal is bounced back toward the source due to impedance mismatches. Attenuation specifically captures the gradual loss of strength with distance.
