                    Notes          By using nanotechnology, Intel believes it can shrink the size of transistors down to the width of
                                   several atoms. IBM and other research labs have created transistors from nanotubes and other
                                   electrical devices (IBM, 2004) and have developed a manufacturing process that could produce
                                   nanotube processors economically (Figure 5.5). Other new technologies include strained silicon,
                                   300-millimeter  production  wafers  (which  decrease  the  costs  of  production),  and  denser
                                   interconnections among components.
                                   Whereas the first Pentium microprocessors operated at 75 megahertz, today’s Pentiums are
                                   available with 3-gigahertz speeds. However, increasing processor speeds at the same exponential
                                   rate as in the past may no longer be possible.

                                     Caution As processor speeds increase, heat is generated that cannot be dissipated with air
                                     fans.
                                   Another brake on future increases in microprocessor speed is more market-oriented:
                                   Most consumers may not need vast increases in microprocessor speed but instead are more
                                   interested in low power consumption for longer battery life and low weight to increase laptop
                                   and handheld computer portability. For this reason, Intel and other firms are designing the next
                                   generation of chips to be less power hungry and lower in weight even if they are the same or
                                   even slower speeds. Other options include putting multiple processors on a single chip.



                                     Did u know? What is nanotechnology?
                                     Nanotechnology uses individual atoms and molecules to create computer chips and other
                                     devices that are thousands of times smaller than current technologies permit.
