Page "Data (Star Trek)" Paragraph 18

Data is physically the strongest member of the Enterprise crew and also is, in ability to process and calculate information rapidly, the most intelligent member.

He is able to survive in atmospheres that most carbon-based life forms would consider inhospitable, including the lack of an atmosphere or the vacuum of space ; however, as an android, he is the most emotionally challenged and, with the addition of Dr. Soong's emotions chip, the most emotionally unstable member of the crew.

Before the emotions chip, Data was unable to grasp basic emotion and imagination, leading him to download personality subroutines into his programming when participating in holographic recreational activities ( most notably during Dixon Hill and Sherlock Holmes holoprograms ) and during romantic encounters ( most notably with Tasha Yar and Jenna D ' Sora ).

Yet none of those personalities are his own and are immediately put away at the conclusion of their usefulness.

Also, the abilities of Data's hearing are explained in the episodes The Schizoid Man and A Matter of Time where his hearing is more sensitive than a dog's and that he can identify several hundred different distinct sound patterns simultaneously, but for aesthetics purposes limits it to about ten.

Throughout the series, Data develops a frequently humorous affinity for theatrical acting and singing.

This is most definitively demonstrated in Star Trek: Insurrection where Picard and Worf distract an erratically behaving Data by singing two parts of A British Tar, compelling Data to sing the third part.
