Student essay written in en (native language: French, CEFR level: A2, field of study: Informatique et lectronique)

I am writing a sample text. I changed it again.
Now I add text in the middle. Removed other part.
Now I have put one too many "enter". I removed the second enter with a suppr. Hopefully this works.
Back to the end of text, this is the final sentence.
