What is /dev/null and /dev/zero
They are a device of course and if a file or any type of output is put there it gets put in a black hole which crushes it into nothingness.
But what is it exactly?
hda is a virtual item that resembles the Hard Drive
cpu simulates your cpu
ram0-19 simulates your ram sticks
but what does null and zero simulate? is there an actual chip on your machine for "null" and "zero"
Another question is why is there two devices if they both do the same thing?
Did someone originally create zero but then someone else thought null was better so they made a symbolic link or something??
Thanks, regards,
