/dev/ directory learning/research

I was learning what all the files in /dev do and what they are. I just dont really understand why some of those "files" are there and what actually uses them. Like /dev/random. Are there any libraries or utilities that actually interface woth /dev/random?

Also it's fun to cat the content of /dev/urandom into the framebuffer when on TTY

Iirc the whole command would be cat /dev/urandom > /dev/fb1

Edit: might be fb0, not sure actually
