Alekos is analyzing his network traffic and is focused on the variance of the delay between packets of data that are sent between two of his sites. What is he analyzing?

Alekos is analyzing jitter, which is the variance in delay between packets. This can indicate issues along the path the packets take. Latency is the time it takes a packet to reach its destination, throughput is a measure of the volume of traffic that can be sent, and signal-to-noise ratio compares the amount of desired information received versus the level of background noise or unwanted data.
