Latency check

Latency is the amount of time a server takes to respond to you - if I said hello to someone, the latency figure would be the amount of time it would take for me to hear their response and it’s the same with ping latency. Generally the closer you are physically to the network the faster it is, as well as the connection type - on my fibre connection to a server in my country it may be as low as 6 or 7 msec, but if I use my 4G connection to a server in Australia it might be as high as 300-400msec.

Jitter is the amount of variance between ping times - if I ping a server 4 times and it gets the same result each time the jitter is considered low, if one packet takes 50msec and the other 100 then there would be jitter of 50msec (I am largely oversimplifying here!)

It’s important to have low jitter for things like VoIP video calls and cloud gaming as it can affect the quality of the experience.
