Digital goods are things that you can't touch or hold in your hands like you do with your toy, book or candy. They are things that only exist on a computer or smartphone like music, videos, games or e-books.
Just like when you trade your toy with your friend, people can exchange digital goods with each other too. But instead of giving away the physical object, they send a copy of the digital file to the other person's computer or device.
For example, if you have a favorite song on your computer, you can make a copy of it and send it to your friend's computer. Your friend can then play the song on their computer just like you did.
Another cool thing about digital goods is that you can buy them online without ever leaving your home. You just need to find the digital store that sells the item you want, pay for it using your parent's credit card or a gift card, and then download it onto your computer or device.
So, basically, digital goods are like invisible toys that people send to each other through their computers or devices, and you can buy them online without ever leaving your house.
