Random comments[edit]

The binary code is a code that the computer uses. The code consists of 2 numbers the numbers 1 and 0. 1=on or true 0=off or false. —Preceding unsigned comment added by (talkcontribs) and it is really boring haven't you got something better to do with your life.

Erm, ascii uses 8 bits, the first number being in case of negative, so it wont have an error when an user inputs a wrong number. Look it up. —Preceding unsigned comment added by Mjonller (talkcontribs)

Actually, ASCII is a 7-bit code. There are various 8-bit extensions of it, but they are more often treated as unsigned than as signed codes; it doesn't really matter though, since it's a code, not a number. Dicklyon 00:37, 23 February 2007 (UTC)

10010101 - is this right?[edit]

Ok, so I want to expand this page about binary codes to examples to what a byte consists of -

-8 bits;8 zeros or ones -values descend from the 1st bit to the last bit from 128, 64, 32, 16, 8, 4, 2, 1.

minimum value is 0, and max is 256

- used for IP addresses, default gateways, and subnet masks

do you think this is the right page to put this in? B'cause i searched and there are different pages like binary code, and binary coding...

i'm not sure where to put it

Merge with binary (numerals)[edit]

Shouldn't this article be merged with the binary numeral system article, because this article doesn't contain much detail and the other one does?--LF2 16:20, 4 November 2006 (UTC)

Perhaps, perhaps not. One can use a binary code - a code where an item being encoded is encoded as a sequence of one of two symbols - without the code being interpreted as a base-2 number. Francis Bacon didn't seem to ascribe any numerical significance to the sequences of 'a's and 'b's he was using as a binary code for letters of the alphabet.

I added a science stub category to this page. If anyone can thinks of a more appropriate stub, or thinks it shouldn't be there go ahead and change it. davekeeling 15:50, 1 February 2007 (UTC)

the part for the binary section is wrong...[edit]

For in the section in which it says about binary code it is wrong. I know binary code and am very good at it. It says to make a "r" in binary code it is 01010010. That is wrong. You would have to change the beginning from 010 to 011. That is because for capital letters ONLY you put 010 at the beginning but for lowercase letters it is 011. Then after that you would simply put the binary number for each letter. The binary number for each letter is the number it is in the alphabet put into binary but it has to have one of those beginnings to it or it os just a number and not a letter.

Merge to binary[edit]

The following is a closed discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the proposal was consensus opposing merge

I think this whole page should be merged into Binary and replaced with a redirect to same. This page is confusing and almost incoherent as it is. It's certainly not a proper dab page. If you cleaned it up, it would either duplicate Binary, or duplicate Binary numeral system. Objections? Please be specific in what you would do instead, if so. Thanks! —DragonHawk (talk) 05:00, 20 March 2007 (UTC)

Oppose Makes no sense —Preceding unsigned comment added by Omegacommand (talkcontribs) 00:29, 28 March 2007
Hi, Omegacommand. Would you please explain why you think it doesn't make any sense? I've explained why I do think it makes sense; it seems fair you explain why you think it doesn't make sense. And please, sign your posts on talk pages. Thanks! —DragonHawk (talk) 04:33, 28 March 2007 (UTC)
Oppose I agree with Omega. It doesn't make sense to merge it with either Binary OR even Binary numeral system. If you really wanna merge it, let's consider merging the following two with this: Executable file, and binary file. K^ aka Fooly-Dooly-00000 00:36, 14 June 2007 (UTC)

I totally agree... yeah

Oppose. They are totally different things except that both use bits.  --Lambiam 16:31, 1 May 2008 (UTC)
Oppose. Binary is really a disambiguation page at this point, and I think it should stay that way, since there are a lot of related topics. Binary code isn't quite the same thing as binary numbers, either... the various systems of representing data using binary numbers are different from the numbers themselves. I agree with you that this page is confusing and incoherent... and even if cleaned up, this page isn't really a significant topic -- I don't think it'll ever be a nice, fat little article. If I get the time, I'll try to clean it up. Indeterminate (talk) 11:12, 3 May 2008 (UTC)

Requested move[edit]

The following discussion is an archived discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the proposal was PAGE MOVED per discussion below. -GTBacchus(talk) 01:50, 26 March 2009 (UTC)

This article was originally at Binary code, which has been converted to a dab page of questionable utility: of the other two entries on the dab page, the first entry is merely an example of a linear code and doesn't even have an article. The other entry is binary numeral system, which is not a code, and anyone identifying it with code is probably looking for this article. It follows that the primary, if not only, context for which "binary code" would realistically be used is in the context of computer code (or more precisely, data encoded in binary). The other possibilities are just as easily served with hat notes, if even that, and there is also the master dab page at Binary. Therefore, I am requesting that this article be moved back to its original title at Binary code, over the current dab page. Ham Pastrami (talk) 06:00, 20 March 2009 (UTC)

BIASED History of Binary code[edit]

There is no mention of Pingala in this section. His work is an important ancient contribution to the concept. Here's a summary of the information missing from this article:

An Indian scholar Pingala (2nd century BC) developed the binary system for describing prosody in his Chandaḥśāstra. The procedure of Pingala's system is as follows:

  • Divide the number by 2. If divisible register 1, otherwise register 0.
  • If first division yields 1 as remainder, add 1 and divide again by 2. If fully divisible, register 1, otherwise write 0 to the right of first 1.
  • If first division yields 0 as remainder that is, it is fully divisible, add 1 to the remaining number and divide by 2. If divisible, register 1, otherwise register 0 to the right of first 0.
  • This procedure is continued until 0 as final remainder is obtained.
Pingala is mentioned in the third paragraph. There's just no reason for him to appear at the very beginning of the article when other binary systems clearly predate Pingala's work. For example, one of the binary-like systems described in the article dates back to the 9th century BC. Why should it appear after Pingala? It makes most sense to structure the history section chronologically.--Rurik the Varangian (talk) 17:20, 25 April 2015 (UTC)
where would you suggest we put the section noted above?-JG (talk) 18:42, 25 April 2015 (UTC)


we have been learning about binary it is awsome — Preceding unsigned comment added by (talk) 09:15, 13 May 2015 (UTC)

Removing Morse Code[edit]

Before my change, the Morse Code section in "Other forms of binary code" section contained the following text:

"Morse Code is a method of transmitting text information as a series of on-off tones, lights, or clicks. Any boo lean system such as this, which encodes meaning, is a form of binary code."

This is not accurate, as technically Morse Code (as described on Wikipedia page), apart from the obvious dot and dash, also uses a pause of length equal to 3 dots to encode end of letter, and a pause of length equal to 7 dots to encode end of word. Dot, dash and these two forms of pauses give 4 different characters used, therefore it is not a binary code.

For example it would not be possible to distinguish between AE (.-<pause>.) and R (.-.) if Morse Code would in fact be only binary and would not contain pauses that do carry information.

Given the above, I'm removing the Morse Code example from the "Other forms of binary code" section.

gynvael.coldwind//vx 22:24, 3 July 2015 (UTC)

I've spotted that List of binary codes also contains Morse Code as an example, though in that specific case it's explained that Morse Code can be encoded using just two characters if a specific encoding schema is used. While this is true, this doesn't mean that Morse Code is a binary code - it means that Morse Code can be encoded in binary code, but that doesn't make it a binary code (e.g. UNICODE characters can also be encoded in binary code, which also doesn't make UNICODE a binary code).

Binary codes, binary numbers, and which articles should discuss which[edit]

Binary number#History discusses a number of binary coding systems that predate Leibniz's Explication de l'Arithmétique Binaire. Those don't seem to involve treating the binary encodings as base-2 numbers, however, so perhaps those schemes should be moved to Binary code#History of binary code, with Binary number#History mentioning those binary code schemes in passing and linking to Binary code#History of binary code. (It sounds as if the scheme used by the residents of the island of Mangareva in French Polynesia may have been a number system, in which case it should remain in Binary number#History.)
