Aren’t the Olympics free?

Might be an issue with fonts?

Honestly, just use Debian. It can run under 200MB of RAM (default install), so it beats all distros on the list except for TinyCore and SliTaz, and it actually has packages.

I’ve seen many references to TCP/IP as meaning IP + everything-on-top, usually when talking about other networking technologies like UUnet, OSI, etc. Also as the TCP/IP stack, usually meaning the (Free)BSD networking code used in other systems.

Apart from being open source what is Linux?

Could I not create my own operating system that is different to windows or Macos and call it Steve
