In the Unix world, there are no “drives” as per Windows “c:\”, “d:\”. There is only a single top level directory known as “/” or “root”. This doesn’t mean that you can’t read floppy disks, have second partitions, second hard disks, etc.
I wanted to add a quick note about why I chose the name “dev.ihgreenman.com” for the name of my tech/math blog. I chose it because it has a dual meaning — depending on which side of the Unix/Windows debate you fall upon.

In the Windows/Microsoft world, dev is an abbreviation for developer, development, or development work depending on context.
Under Unix, dev is where device files (pointers to anything that isn’t a file) are stored. More about what this means later.
