[QUESTION] How does Word save your unsaved progression if your PC turns off randomly

Hi, today my professor asked the whole class this question:

“Imagine you are using Microsoft office word and you have a hundred rows done. The last time you saved your work, you were on the 8th row. Suddenly, the laptop stops running and you are furious because hours have gone down the drain. After some time you decide to do it all again and turn on the laptop. You get into Word and suddenly the whole 100 rows you typed appear again on your screen. How does Word do it?”

I know when you save your files, RAM stores the file inside the HDD. But since the 92 rows were unsaved and RAM is only a temporary memory hardware, where does the file go, if not lost? Help me anyone :))
