We can agree that there are limitations originating from physical principles (constanats) computer speed. On many sites I read common sentence was one referring to CPU frequency increment. It’s sad that as we increase CPU’s working frequency we have to locate memory (RAM) closer to CPU because this length has to be smaller than the wave length of given frequency, why ? Than there’s the problem with constant for speed of light…. What are your thoughts on this subject, how do you think we’ll try to pass this barriers?
