Mbps (Megabits Per Second): One megabit is equal to one million bits or 1,000 kilobits. While "megabit" sounds similar to "megabyte," a megabit is roughly one eighth the size of a megabyte (since there are eight bits in a byte). Mbps is used to measure data transfer speeds of high bandwidth connections, such as Ethernet, cable modems or dsl modems.
Ping: The ping is the reaction time of your connection–how fast you get a response after you've sent out a request. A fast ping means a more responsive connection, especially in applications where timing is everything (like video games). Ping is measured in milliseconds (ms).
Jitter: 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.
