Short answer: Configure = customize.
Long answer: It’s how you tell software/hardware what to do. Like, a router won’t know your WiFi password unless you configure it.
It matters because defaults are generic. You wouldn’t wear shoes that don’t fit, right? Same idea.
For tools, maybe try [Windows Settings](https://support.microsoft.com) or macOS System Preferences—super basic but great for seeing what is configure in real life.
