Gopher is like a very simple way for computers to talk to each other and share information. Imagine you have a toy phone with only two buttons, "yes" and "no". That's kinda like gopher.
When you use a regular web browser like Chrome or Firefox, you're using a special language called HTTP to talk to other computers which help you get information that you want. Gopher has its own special language for talking to other computers.
Gopher is very old, older than you or me or even your parents. It was made way back in the '90s as a way to share text-based information with other computers on the internet. This was before the colorful and fancy websites we see today!
When you use gopher, you might see a list of things you can click on, like a menu at a restaurant. Each item on the menu has a number or a letter next to it. When you click on an item, gopher can give you a list of more things to click on, just like when the waiter gives you a menu.
Even though gopher is old and simple, it's still used sometimes by people who like to share simple text-based information without all the fancy stuff. That's why it's still around today, even though it was made a long time ago.
