Does the term "command" have various meanings depending on the context?

I'm a junior developer struggling with a very basic knowledge in the software engineering.

I heard the term command for the first time when I studied command pattern in GoF design patterns.

But I've noticed command has to do with not only design pattern, but it also has to do with something I'm not familiar.

I found command with words such as event, command handler. Those commands are all the same? Or Is my thought right that command has various meanings in various context?

I've googled for about three days, but with no success. Could you help me with this?

Thank you so much. Happy belated new year.
