Architecture: a large concept

If I think to architecture, the first thing comes me to mind is a material object: the beginning shape of this object is confused but little by little it become more defined, taking the form that goes from a Pyramid to a Greek temple and so forward till today’s buildings. Thanks to the years of study that I’m passing through, my vision of architecture is becoming largest. Indeed, the second thing I think, when I listen the word architecture, is a space plan, which may bring with it a building project or less. I can continue, trying to taking out of my mind something else about what I think for third and so on, and for last, I arrive to think to PC architecture.
Yes, I said PC architecture, look at this:

Doesn’t remember you something else that just a PC? Look down
I’m not crazy! Think beyond.

Comments and corrections are pleasant.
