Tino is correct - the hardware is essentially a secure storage area for
your keys.  It also will do things like "onchip key pair generation using a
hardware random number generator, along with public key signature,
verification, encryption and decryption",  and it contains things like
hashes of your CMOS (BIOS data area) so nobody can mess with it (ie
viruses).

The software that comes with it is essentially an encryption/decryption
stack, so you can do things like encrypt portions of your hard drive.

It doesn't send any data to anyone, it doesn't have anything to do with DRM
(Digital Rights Management). Its primary purpose is to protect YOUR
software, keys and data against attack from viruses or hackers.   And you
don't have to use it at all if you don't want to, you can turn it off in
the BIOS.  And, only certain models come with the chip, you can specify if
you even want it on your system or not.

Sound better now?
