defined as variation of delay or variation of packet arrival time is a QoS parameter
A
Rate
B
Jitter
C
Latency
D
Packet loss
E
Throughput
Explanation: 

Detailed explanation-1: -Jitter is the variation in time delay between when a signal is transmitted and when it’s received over a network connection, measuring the variability in ping. This is often caused by network congestion, poor hardware performance and not implementing packet prioritization.

Detailed explanation-2: -Delay jitter is defined to be the mean deviation (smoothed absolute value) of the difference in packet spacing at the receiver compared to the sender for a pair of packets. Learn more in: Adaptive Transmission of Multimedia Data over the Internet.

Detailed explanation-3: -Jitter: it is the variation in delay for packets belonging to the same flow. High jitter means difference between delay is large; low jitter means variation is small. 4. Bandwidth: different applications need different bandwidth.
