To understand about about using absolute and relative URLs, it
is important to first understand about relative and absolute path names.
- Absolute pathname
- Something which identifies a file or a directory irrespective
of the current state of the user or the user's program. The
user's "current directory" is part of the user's state.
- Relative pathname
- Something which identifies a file or a directory in a way
that depends on the state of the user or program, usually
depending on the program's (or user's) "current directory".

and there are things that are not covered.
