Net Tab "tooltip" question

[andrew8088]

I have a pretty good idea of what each of the four bits of info on a
Net tab 'tooltip' is, but I just want to clarify I'm understand it.

"Queuing" (represented in brown), is the time spent requesting and
waiting for a file
"Receiving data" (represented in grey) is the amount of time spent
loading the file from the server
"DOMContentLoaded" (blue line) is an event fired when the page (minus
the images) finishes loading
"Load" (red line) is an event fired when everything is finished
loading

Is this correct? Where does the cache come in?

Thanks,
Andrew

Yes, this is the elapsed time the request spent in a browser queue
waiting for a network connection

Yes

If the response comes from the browser cache, the "Receiving data"
color is changed to "light gray" and represents the time required to
read from the cache.
