I've spent a lot of time with a number of hardware manufacturers recently, trying to get a glimpse into the next generation of processors and the ways in which they'll impact future gadgets and PCs. In all my meetings, one term has arisen time and again: SOC, or system-on-a-chip.

Traditionally, chips have been created independently and then coupled together to provide multiple computing features. For example, a manufacturer would create a core processor like an Intel Centrino with a built-in Wi-Fi radio, and then attach that to a systems board, perhaps linking it together with a separate graphics co-processor, in order to deliver enhanced PC graphics. Another might take an ARM core processor and then add on additional features like extended graphics to enhance device functionality.
