figured it out
it's a very based operating system, and i will elaborate
basically, plan 9 from bell labs (yes, the entire thing is its name, "Plan 9 from Bell Labs". it's a pun on the name of the terrible movie "Plan 9 from Outer Space") is an operating system that uses multiple computers as one computer
for example, if you set up a plan 9 server, it's just running plan 9, nothing special
but if you download drawterm, the external terminal for using plan9 on other machines, when you connect to that server, your computer becomes part of the system. it uses your resources, and can access your files
essentially, you can make a big ol supercomputer with it if you really wanted
