why we don't make fractions more than binary for computers ???(read the details complete)?

Question

note like quantom computers.i mean some thing more than on & off. for example 0=no voltage 1=0.1voltage 2=0.2voltage .....10=1voltage. a fraction that explains something more than on & off for hardware and software. building new hardwares designing new programs. its a difrent fraction and dont works like binary fraction. logicaky it has more thane two chioces(on off)and works smarter. we can make complex codes on this system works smarter.the memory gets biger...... and something more than computers than now we have

FOR HARDWARES WE CAN US SOLITANS THE ELECTRONIC PACKS

I KNEW THAT THE HARDWARE IS PROBLEM SO UNLEASH YOUR IMAGINATION AND BUILD ANEW HARD WARE
I THINK THAT I CAN MAKE IT AFTER MY COLlEGE

Answer 1

voltage fluctuations and outside interference will affect the outcome of the number. An example would be adding 2 numbers, say 3 + 4. If 3 is represented by .3V and 4 is represented by .4V, somewhere between there you have to have a dividing line. Say 3 is anything between .25V - .35V and 4 is anything between .35V and .45V. If you have voltage fluctuations or interference of just .05V, the number could be interpreted wrong.

With digital (1 or 0), the voltage to represent 0 is usually around 1.2V or less, and a 1 is represented by 2.5V or more (assuming 5v source). Noise and fluctuations will not be great enough to affect the outcome.

Someone else also made a good point that most data is stored magnetically (even optically would be difficult), and would be near impossible to store anything other than a 0 or 1.

Answer 2

Computer chips today use binary logic, which means that only two states are possible (0 or1). Ternary logic(-1,0,+1) was used in the past (50's) but it wasn't as effective (because of hardware limitations) and it was abandoned.
What you are talking about is a base-10 computer which is much more complicated.
See, it's not as easy as you think. It's not like you can simpify a 2 number addition to just adding the voltage on 2 wires. What would happen to the carry in that case? That's not the way it's done. Logic gates are used in certain combinations to perform various operations. Binary logic is the simplest to implement and thats why it's dominant.

Answer 3

It isn't quite that simple.

What you are describing is a decimal computer. Part of the difficulty lies in hardware. We would need a device to accurately measure the voltage. We then would have to convert the voltage numbers into something useful and so on.

I am sure that smarter people than I are looking at all of the ways to improve computing and my bet is that the concept of Quantum computing is what a digital machine would have to approach to be useful.

Answer 4

I think the main reason is because of storage(hard drives). For the most part, hard drives still use magnetic disks and the polarity of a certian sector determines whether the bit will be a one or a zero. Now if someone can figure out how to store fractional data and then make it cheap, then that would change computers but until we can store the data for later use, people won't like it.

Answer 5

What language are you speaking ?

Binary is used because in the old days, circuits were either on or off. Detecting partially on circuits would be too costly to implement.

Maybe we will see advances in this area in the future.

Answer 6

There have been ternary devices but there were never largely accepted. Some people do make them still.

And there were some analog computers made too. Probably there are clubs of people who use them.

But it's easier to design both hw and sw that's binary. And easier means cheaper.

Answer 7

Your system would involve much more. On or off is simple and unmistakable. your system is prone to misinterpretation.

It would need more than just a switch and that's what 01 is. but set 5 of those in a line and you have what you propose. Your system would need more space I assure you.

ummm dont have a clue wht ur on abt....just wanted 2 points...
