Ping and jitter are components of latency, which is the amount of time it takes for a signal to go from point A to point B. Ping is actually the tool that’s used in order to measure the latency, but ping is typically also used to refer to latency as well. Jitter refers to the amount of variation in the latency when multiple ping tests are performed. Wired connections such as Cable, Fiber, DSL, etc. will always have a lower latency than wireless connections such as Satellite, LTE, Wi-Fi, etc. Lower latency and lower jitter is beneficial in applications such as online gaming and VoIP (Voice Over IP) communications
