Why don't they use more than just 0s and 1s for computer?

why stop there. why not use infinitely many symbols. you could express literally any message using a single symbol

>>8719972
Look up quantum computing

>>8719972

because circuits are either on or off.

>>8719972
Trinary computers have been built, but they're vastly more complex and aren't as fast.

this is what happens when math and physics students attempt computer science

>>8719997
I would guess that OP isn't even a STEM student

>>8719972
Computer hardware uses high/low to indicate the two states. More states would require voltage measurement. It is because of practical constraints.
Only 9 combos are available in one tri-bit. They would still have had to join tribits for the original 256 characters in one character set. Multiplying by two is easy (2^20 is1048576), but even 3^5 is too onerous to calculate.

>>8719997
I hate it when people are snarky to those who don't study their field. It doesn't make you look smart

OP computers don't read or write tiny little characters like 0,1,2 etc. They read switchs which are either in an on or off position which can be represented as 1 and 0. You might be interested in looking into quantum computing but beware those who say it's coming any time soon

Fun fact, some early computers used a decimal system. Each bit could be at one of ten voltages corresponding to 0-9. They stopped making those when they realized the problems with bit decay that came with it.

1) you worded that retardedly

Because it is hard to decide between more then 2 different states.
Transistors who can decide between 2 states are very easy to build and more importantly can be build on very small scales.
Having a transistor who can decide between 3 states is vastly more complex and harder to scale down.

Ternary computers have been build, but they are not really useful.

>>8719972
Is there any advantage to this at all?

>>8719972
Because 1 and 0 represent true and false.

>>8719980

NO

NO GOD DAMN IT

THATS NOT HOW IT FUCKING WORKS

AAAAAAAGH FUCK NO
NO
NO NO NO
NOOO

Assuming there were no engineering/physical constraints, are there reasons that cause some systems to be better than others? would a 1000-bit computing be better than binary computing?

>>8719972
The actual answer is that EM interference can change the voltage in a wire. 0 is therefore represented as "somewhere between 0v and 2v" and 1 is represented as somewhere between "3v and 5v." In other words binary encodings are more robust for storage and transmission than non-binary encodings. This also applies to mechanical devices like optical discs.

>>8721159
This.

Because voltage fluctuates. Using a higher base would increase the chances of the numbers getting mixed up.

>>8719982
mind = blown

>>8719976
That is actually possible. They are called analog computers.You pretty much have an infinite amount of states which each represent a real number (say, a voltage or current). Because their precision heavily depends on imperfections of the electronic or mechanical parts (which are subject to decay), they have been replaced by digital computers. Part of the components are still in use to this day though not labeled as analog computers.

>>8719972
If I remember correctly, e actually has the best ratio of number of symbols to word length or something, so 3 symbols would actually be better than the 2 we are using in that regard (I don't remember the details off the top of my head). People actually tried building ternary computers in the past, I believe.

However, it turns out that having only 2 symbols is just easier and less prone to error and therefore faster in practice.

Well, a 0,1,2 might work or more of 0-9 counter base. Each number would represent a power/frequencies

>>8719997
They ask question about the other field?

What the actual fuck is your problem?

>>8719972
Analog transistor computers exist. And in fact the cheaper flash memory uses multiple values to store data instead of binary.

Experience has shown the reliability and speed of digital computing to be better in almost everything when compared with analog computers. But your free to go make one if you wish. If you can make a better bit coin miner for instance you can make millions.

>>8721159
So they should just make one that doesn't have interference

>>8721159
for most data transmission, you don't use binary encodings

i would wager it's more that it's impractical to do logic circuits with more than 2 states

>>8719972
I'm finishing it off using a wikipedia page
www.en.wikipedia.org/wiki/Ternary_computer/
TL:DR; A computer which uses 0,1,2 exists, but using 0,1 is more convenient, check >>8720028 for more info

>>8725304
The wikipedia page didn't load, check out

>>8720473

Oh they're selling them. They're just not actually making them.

D-Wave's computers have been repeatedly shown by independent testers to either have no or little evidence of quantum behaviour - which is admittedly ambiguous because of how bizarre quantum shit is - and absolutely proven to be no faster than standard computers - which is not ambiguous.

This should sort of be obvious since non-commercial scientists were struggling to get 8 qubits working, when this company suddenly came out with a five hundred qubit computer.

So yeah. No.

why not use binary for computations and convert to binary at the end? maybe using a binary coded decimal to decimal converter?

>>8719972

Just use three outputs for 1 and 0 and you'll have as much combinations as you do for 0, 1 and 2 just without the need to build completely new circuits.

>>8719982
This is the answer to OPs question. I'm surprised that OP knows what binary is, but doesn't know why

>OP computers don't read or write tiny little characters like 0,1,2 etc.

This actually made me laugh

Ternary Computers exist and if we can build them with precise enough hardware they indeed are more efficient than binary computers.

It means a radical change not only in circuit development and logic construction but also in the way we calculate in our heads as ternary offers very convenient properties when it comes to written arithmetics.

to anyone thinking binary is the only way computers can exist I recommend you broaden your worldview because you are wrong.

>>8723001
>And in fact the cheaper flash memory uses multiple values to store data instead of binary.

It's kind of funny how we just those extra values to store extra bits per cell instead of trits or quits or whatever.

These are some of the best comments in the thread. There is no need to link OP to youtube links about quantum computing because that is kind of an unrelated thing to what he is asking.

I just read up on the analog computer wikipedia page and it's interesting af. I highly recommend anyone to do the same, and the read the four comments I linked.

>>8719982
more like True and False

>>8723827
I feel like this is going somewhere. What if the data itself wasn't transmitted by copper but by fibre optic? You could use a much more concise range of wavelengths to decide between each state and there would be minimal interference as it doesn't interact as much, or even at all as electrons do in a small magnetic field

>>8728125
actually >>8721159 is a pretty shit comment senpai

>>8719982

OP is clearly retarded or trolling.
