"Linux" is a kernel. Its current edition is 6.18.
Various people and organizations package this kernel with various tools,
file systems, libraries, shells,installation methods and utilities to

distributions.
While most of them now have a graphic interface component, almost every

that don't are not intended for human interaction.

They did not ever teach or certify knowledge of about browsers. While
certainly important, browsers are simply a category of applications. They
have NEVER been a "fundamental foundation" of Linux-based operating
systems.
