[TYPO3-english] What does these warnings mean?

Sometimes I see warnings like:

*Warning*: mysql_fetch_assoc(): supplied argument is not a valid MySQL
result resource in
*/home/elmit1/public_html/typo3_src-4.2.1/t3lib/class.t3lib_db.php* on
line *808*

*Warning*: Cannot modify header information - headers already sent by
(output started at
in */home/elmit1/public_html/typo3_src-4.2.1/typo3/template.php* on line

What do they mean? Is it a programming error that causes that or a
network error?
