What is a common impact of jitter on VoIP calls?

• A. Increased connection speeds
• B. Disruptions in voice quality and clarity
• C. Elimination of data packets
• D. Improved audio synchronization

Answer: (B)

Jitter refers to the variability in packet arrival times during the transmission of voice data over a network, particularly in Voice over Internet Protocol (VoIP) calls. When jitter occurs, it causes packets of audio data to arrive at their destination at irregular intervals. This inconsistency can lead to disruptions in voice quality and clarity, creating a choppy, garbled, or delayed sound during conversations. The fluctuating timing can make it difficult for both parties to maintain a natural conversation flow, resulting in an overall degraded user experience. In contrast, increased connection speeds would not directly relate to jitter, as higher speeds do not mitigate the effects of packet timing variability. Similarly, while data packets may be dropped in some cases (due to network congestion, for instance), jitter itself does not eliminate packets but rather affects their arrival times. Improved audio synchronization is not a result of jitter—as more consistent packet timing would be required for that, making it clear that the common impact of jitter on VoIP calls is indeed the degradation of voice quality and clarity.
