My link in SharePoint and your link

On the Internet today, a friend asked me what is the difference between "your link" and "my link" in Sharepoint. I remember that I was confused at first, but after I used it for a long time, I realized how much it was, the so-called "your link" refers to the link that someone else gives you (with my little experience and what I guess, haha ......), "My link" is added for myself. For example, if I see a document and are interested in the content of this document, you can use the "add to my link" option in the menu, and then pull the "my link" Web part in your "my website, hey, you added all here. Haha .........
