Binary Numbers

Does computers read binary numbers (0's and 1's)? If then, where? How does this process work?

Thanks,

J.

In positive logic:

1 = high voltage
0 = low voltage

The reverse is true in negative logic.


The computer can then feed these voltages through transistors which are hooked together to form logic gates. The logic gates can be configured to add, subtract, multiply, divide, etc. The logic gates all operate in Boolean algebraic logic. For instance, in Boolean Algebra, 1+1+1+1 = 1. Any number of 1's added together makes a 1.

Gosh, so many answers. There's the cache, the RAM, magnetic media like hard drives, optical media like CDs and DVDs, tape media, and networks like the WWW... each encodes information differently.

Do you really want to know how the hardware works? For example, precisely how a binary "1" is stored in a memory chip, how binary data is copied from memory chip to processor and vice versa, etc? Have you similarly enquired how a television works? Do you want to know what a transistor does, or do you want also to know precisely how it does it?

Well, I want to know how binary works in a computer. I've learned the basics of it, like how the gates and flip-flops work with the 0's and 1's (which is the Boolean logic). I want to know a little bit more information on binary. I was also curious how the hexadecimal process works.

Hexadecimal is just a convenient way to represent the 0s and 1s. Actually I think it's misleading to call computers binary; a 32-bit computer (that is, a computer with a word size of 4 bytes = 32 bits) does most everything in base 2^32.

Do you know about RAM refresh and the like? Where should we start?

Really, this is a very broad topic... All of Computer Engineering is about this concept. I'd recommend looking into computer engineering degrees for college.

Also, you've expressed interest in CompSci research, so I'd recommend looking into a dual CPE/CS program somewhere.

I was going to do that at one point...
