Exam N10-008 topic 1 question 606 discussion

B. Latency Latency, also known as delay, is the time it takes for data to travel from the sender to the receiver. It's the delay between the time data is sent and the time it's received. Latency is usually measured in milliseconds (ms). Imagine sending a letter: latency is the time it takes for the letter to arrive at its destination. C. Jitter Jitter is the variation in latency over time. It's the difference in delay between packets of data. Jitter can cause problems with real-time applications like video conferencing or online gaming, where consistent latency is crucial. Think of jitter like the irregular arrival times of buses at a bus stop: sometimes they arrive on time, sometimes they're early or late.

C .Jitter Jitter is a term used to describe the difference in latency between packet flow from one client to another. Like latency, jitter is measured in milliseconds and is most impactful to stream audio and video services.

C. Jitter In the context of VoIP (Voice over Internet Protocol), the term "jitter" is used to describe the inconsistency in the amount of time it takes for data packets to reach their destination and return. Jitter can result in variations in the delivery times of VoIP packets, leading to disruptions in voice quality. Therefore, the best term to describe the issue of inconsistent timing in data transmission for VoIP is C. Jitter.

Jitter is the best answer because the question mentions "significant inconsistency" in round trip times. If the delay was fairly consistent, you could call it Latency, but not here.

C. Jitter Jitter refers to the variation in packet arrival time at the receiving end. It can result in the loss of data packets or poor voice quality in VoIP systems due to the irregular delivery of data. Jitter is a significant concern for real-time applications such as VoIP, video conferencing, and online gaming, as it can cause delays and disruptions in communication. Bandwidth (option A) refers to the capacity of a network to transmit data. Latency (option B) is the time delay between the sending of a data packet and the receiving of a response. Throughput (option D) refers to the actual amount of data that is successfully transmitted over a communication channel. While all these factors are important in network performance, the inconsistency described in the scenario points to the issue of jitter.

Latency is in relation to round trip. Jitter is from sender to receiver. There is return jitter when you talk about receiver back to sender, but it’s not a typical thing to take into account when referring to jitter. That’s my take on this at least.

Latency is time jitter is packet order
