how nanotechnology will increase the speed of the computers?????

Nanotech is the most fascinating technology of the latest techs. One interesting feature of nanotech is miniaturisation. In future nanotech will help to insert a small nanorobot into a baby's body after its born and that nanorobot works as the WBC and fights against all the disease pathogens that attack the body. So the baby wont get disease throughout its life!!!
