NEW YORK (TheStreet) -- Apple (AAPL) announces its fourth-quarter earnings Monday after market close, and its results impact not only investors but members of its supply and partner ecosystem, as well.Although Apple traditionally develops much of its technology in-house -- the iPad runs on a new, custom-designed chip -- the Cupertino, California-based company still relies on a vast network of external suppliers to manufacture pieces of its popular products. Well known for its obsession with protecting trade secrets and intellectual property, Apple does not provide an official list of its suppliers and requires that its key partners maintain a strict code of silence. However, firms like iFixit and iSuppli that specialize in taking apart and analyzing gadgets have provided insight into the manufacturers of Apple's major components through "teardowns" of its products. Research has revealed that Apple relies on many of the same suppliers for the iPhone, iPod Touch and iPad.
