What is a breakpoint continuation?

In the case of poor network conditions, for file transfer, we hope to be able to support the transfer of some data at a time. In fact, the breakpoint continuation is literally meant to continue the transmission at the disconnect point of the download, without having to start from scratch. So after understanding the core of the breakpoint continuation, I found that it is actually very simple, and the key lies in the grasp of the transmission breakpoint. I drew a simple diagram of my own understanding:
