Exam N10-008 topic 1 question 844 discussion

Jitter refers to the variability in packet arrival times. When packets arrive out of order or with significant delays between them, it can lead to jumbled and distorted audio in VoIP calls. This is because VoIP relies on timely and orderly packet delivery to maintain the quality of the audio stream. B. Bandwidth: While insufficient bandwidth can cause issues with VoIP, it typically results in dropped calls or reduced audio quality rather than packets being out of order. C. Latency: High latency can cause delays in audio but does not typically result in packets being received out of order. D. Delay: While delay affects the time it takes for packets to travel from source to destination, it does not specifically address the issue of packets arriving out of order, which is more directly related to jitter.

A. Jitter Jitter refers to the variation in packet arrival times. In VoIP, when packets arrive at different times or out of order due to varying delays in the network, it can cause issues such as jumbled or distorted audio. Managing jitter is crucial for maintaining the quality of real-time communication like VoIP. Bandwidth refers to the capacity of the network but is not directly responsible for out-of-order packets. Latency is the overall time it takes for a packet to travel from source to destination but does not explain the out-of-order delivery. Delay is similar to latency, referring to the time taken for data to travel across the network, but it's the variation in delay (jitter) that leads to the described VoIP issues.

out of order/sequence = jitter
