Computer Sci Undergraduate Certificate

If it worth it to get a undergraduate certificate in Computer science?

What exactly is a “certificate” in CS?

The uni I want to go to offers undergraduate certificates so I take classes that fufill that area since im not majoring in it so if I wanted to continue with graduate studies like masters, I could apply with that certificate

So what’s the difference from a minor?
