Just want to warn you not to write about the ones and zeroes, on./off. and so on.
Rather, the question is that it would be possible to store in memory ten States, instead of two. Accordingly, the memory access would be faster. Before, when everything was beginning maybe it would be difficult to implement technically. But now with the current processes is there no possibility to do this?
I'm not an engineer and not an electronics engineer, so maybe not quite correctly asked the question. But, nevertheless, the question arose.
Worse noise immunity... or something. I'm not talking about their computers, and the methods of communication and storage of information. See, when you are transferring data are now two States - 1 and 0. Suppose that we transmit the data to electricity (not optical fiber, and the usual twisted pair). Roughly speaking, 0 is not the absence of voltage, this voltage is from 0 to 1 volt (the number of noodle). This covers measurement error, interference static and other spurious stuff. Accordingly from 1 to 5 volts is 1. Now in the case of the decimal scale is narrowing - 0 is from 0 to 0.5 volt, 1 - from 0.5 to 1, etc. Such a system would be less jamming and more demanding to the final measuring signal.
The transmission in this case is only an example. This all applies to storage and transmission in any form.
The highest density of storage has a number system on the base of the natural logarithm the number e that is approximately equal to 2.71
This number is between two and three, but ternary logic to implement more than binary, though, because working in the linear mode, the transistor gives off far more heat than the running key.
Your idea that the memory access might be faster at least is not justified.
How do you physically represent 10 of the States of a single transistor is open, closed, ajar, and so on or as you represent 10 of the States of magnetization of the disk, magnetized, slightly magnetized, magnetized even weaker ... when was the Trinity system, but refused because hemorrhoids. In General, on the physical level is more difficult to implement with the level transistor logic, which is now, and why? Decade only person more convenient due to the number of fingers, other advantages of the decimal system.
The opportunity is there, but why? And faster, it will not work. because the signal only two States there is no-0/1.
hmm, it's hard to imagine a system element, the element of the universe, who holds in ten States and they can instantly change. besides, you need to have this item you can practically implement on a technical stage of civilization - bicubic technology of neyrotekhnologii, p-n-transitions, subtomentosus particles and so on.... IMHO, it is not suitable. spin-electron - and he can only go in two directions, as well as p-n-transition (n-p-transition), Neurocomputers have the same bekoutou structure - like there are three States.... don't exactly remember, but something like that. but below 10 or so, quite difficult, and probably not why.
