(Redirected from ATAPI). ATA Packet Interface (ATAPI) is a protocol that has been applied to Parallel ATA and Serial ATA that allows a greater variety of devices to be connected to a computer than ATA would allow.ATA was originally designed for, and worked only with hard disks and devices that could emulate them.Redirected from ATAPI).

Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. Gross (macroscopic) anatomy is the study of body parts visible to the naked eye, such as the heart or bones.
Structure and function can't be easily separated, so most students study the two disciplines as one coherent whole. You might, for example, learn about the structure of cells at the same time as you learn about how each organelle -- a tiny organ within a cell -- functions. The names of the organelles and their appearance represent structure, but an explanation of what these organelles do is an example of function.
