choke/rate/tick rate/ping?

[I have no time for games]

Hi im new to here so let me know if im posting this in the wrong place.
im wondering whats the connection between choke/rate/tick rate/ping
and this is what i thought: ping is the latency of the client to the server,
tick rate is the update rate of the server.
choke: happens when heavy traffic on internet?
and rate which i have no idea what it does, i was boring today and increase it from 80000 to 128000 and i had a heavy choke(around 30-40) but more stable ping.

Can anyone explain why?
