What is a touchback in football?

I often hear the term “touchback” while watching National Football League games but don’t fully understand it.
When exactly does a touchback happen, and what does it mean for field position?
A simple explanation would really help clarify it.

In the National Football League, a touchback happens when the ball is downed in the end zone of the receiving team after a kickoff or a punt. Instead of trying to return the ball, the team simply takes over at their own 25-yard line for kickoffs or the 20-yard line in certain other situations. It’s a neat way to reset the play without any return attempt.
