Downloading file on custom page

Question

I have created a site/portfolio, locally for now(will try to take it online soon) and I have a question. I have made a download button for my CV and I have connected it to my CV file, which I've put in the same folder as the html, css and js files. Of course if I take it out of the file the connection is lost and it can't be downloaded. My question is: when I take this site online how will the file be connected and generally how is this done? Is it through a database?
Just informing you that I have obviously yet, to check how the uploading on the web will be done(host,server etc), I am a complete novice at this.

Answer 1

Upload all your folder files on your hosting server. The CV file also has to be in those folder files

The way you used to link to your CV file when the website is local , it will work the same when you host your website

Ex:
If The link to you file was (../assets/CV.pdf), it will work the same when you host your website

Answer 2

Ok I get it. Can you explain where will the file actually be. Like will it be on the host's (mine) database, which is created automatically through the hosting service I will choose?
