How to screenshot on a Dell laptop and save the image?

I just bought a new Dell laptop and I'm still getting used to it. I've been using it for a few days now, but I've realized that taking screenshots is not as straightforward as I thought it would be. I know there are some keyboard shortcuts and software options available, but I could really use a clear guide on how to screenshot on my Dell laptop and save the image. I've tried searching online for answers, but all I get are generic instructions that don't seem to apply to my specific model of laptop. That's why I'm turning to you - hopefully, someone who has experience with Dell laptops can provide me with a step-by-step guide on how to screenshot and save the image. I'd really appreciate it if you could explain this in simple terms, so that even a non-tech-savvy person like me can follow along. Thanks in advance for your help!
