All computers are digital now, I don't think you'd ever find one unless you discovered some old computer. Back in the early days of computers they were analog, but now virtually everything catoragized as "computer" is digital. Scientists recently developed a transistor that had the width of an atom. This could certainly revolutionize the size of most electronics.
LOL.
Of course all computers are digital.
Do you know anything about the memristor dicovery though?
We aren't talking about modern computers, we are talking about future computers that will be using memristors, incorporating their analog advantages into future computers. These devices are extrememly tiny and have voltage/current dependant memory (analog), which will be able to store data in an analog manner rather than hi-low voltage states. Incremental resistance changes that freeze with the last voltage level applied if I understand it.
This will work much like the brain, which is analog, and far superior than any silicon device at least in adaptability and function, if perhaps lacking in dependability LOL.
Do you see where that is going? Just because the current state of the art is digital, that doesn't mean that advancements in analog technology can't revolutionize things once again. Actually, grasshopper, digital predates analog!!! Think Morse Code, abacus, heck your fingers and toes
Another example, at one time parallel communication was the fastest thing around, until serial ports were made better with faster processors. In theory, parallel communication is "superior", but in practice computer speeds are so fast now that the difference is nominal and the reliability of serial trumps any speed advantage of parallel...am I not correct?
That doesn't mean that someone might figure out a better way to communicate with parallel lines, but until then serial communication is more commonplace. Parallel ports are for printers LOL.
It isn't set in stone that digital is better.
