GNU/Linux
IS PRONOUNCED "GER-NU" "LEE-NOOKS".How many times have I been in contact with an agency and cringed when he (mainly he-s) pronounces it "Lye-nucks"? <shudder>. I'll stop now.
GNU is the Free Software Foundation's moniker (GNU's Not Unix), and Linux is the kernel of the operating system. Together they are GNU/Linux - GNU license the tools that you can use with the kernel (eg shells).
Tux is the logo of Linux. You might have seen the grown up Tux (below) more than the baby Tux (above):
