    Internally Linux knows you by a number, not a name. This number is called the User Identity Number or UID. The username that you log in with is just a translation for the convenience of human beings.

    Many distributions use the UID 1000 for the first non-system user (in Knoppix, this is the knoppix user). It's not a universal convention though: Red Hat used to use 500.

    Your files are registered to your UID. If you look at them in another Linux system which has no user corresponding to this UID, you see the UID instead of a name when you list the directory.
