Talk:Data communication

message: The asynchronous versus synchronous communication discussion seems misdleading --- it talks about special cases of general ideas as if they are the only cases. Asynchronous communication is not necessarily controlled by start and stop bits, and the section is written as though all asynch comm. is 8 bit serial. The comments on clock skew in the synchronous comm discussion are also misleading as not all --- in fact, little --- synchronous communication suffers from skew-related data corruption. I would fix this myself except that I tend to be too wordy for short sections.

message: Can anybody tell me that What is the maximum speed of data transfer can be supported by copper?
: not the speed of light.
Telecommunications is a subset of data communications.  There is no need to mention tele-communcations in the first paragraph.  
Do you mean the minimum rise time for a digital bit to transmit across a copper wire, or the maximum number of bits you can get through in a given amount of time?HatlessAtless (talk) 19:31, 18 July 2008 (UTC)
thread_title:  maximum speed 

message: However this method ohg, as there is more interference between many wires than between one.
Could somebody please tell me what ohg is meant to mean?

message: I oppose the merge to the Digital communications. Data can be transmitted by analog means as well as digital. Data is not synonymous with digital. Oicumayberight (talk) 20:02, 27 August 2008 (UTC)
replies: text: Does the first post imply that Digital communications does not involve Digital modulation methods (i.e. digital communication over analog media)? That is wrong. Mange01 (talk) 22:16, 21 October 2008 (UTC)
replies: text: NO. I don't know how you drew the conclusion that I was excluding anything with an inclusive statement. Data transmission is not dependent on digital but can include digital. Oicumayberight (talk) 23:28, 21 October 2008 (UTC)

text: Arguments for a merge: A text book on data transmission and one on digital communication typically involves the same chapters, including multiple access, error control, digital modulation, line coding, data compression, cryptography etc. So both includes layer 6 - the presentation layer. None of them would include routing, process-to-process communication, etc (layer 3, 4 and 5), which would be covered in a book on "data communication" or "computer networks". Anyway, even if there is no support of a merge, the relation between these topics should be clarified in the article. Mange01 (talk) 22:16, 21 October 2008 (UTC)
replies: text: To say that data transmission is digital implies that there is no such thing as analog data transmission. That would be misleading. Oicumayberight (talk) 23:28, 21 October 2008 (UTC)

thread_title: Oppose merge to Digital communications

message: The problem here is not what is or isn't covered by a text book in the field, but with oversimplification of the words in the English language. "Data" may refer to digital data most often, but is not used exclusively to describe digital data. Considering that these articles are often translated in other languages, perhaps a better solution is to make this an overview article or a disambiguation page branching to two separate articles titled: Data transmission (analog) and Data transmission (digital).

message: I removed the following text (added 31 July 2015) from the lead:
:Because of the perfect reproducibility of digital data (lossless compression, nearly error-free communication), a data transfer to any kind storage device, be it permanent such as a hard disk or temporary as RAM, is the basis of data copying or data duplication in the computer age. Moving data is always a combination of a data transmission with data deletion on the sender side.
Per WP:LEAD, the lead should be a summary of what is in the article. More importantly, the text is an observation that storing data involves data transmission, and that does not explain anything about the topic of this article. Johnuniq (talk) 00:09, 21 November 2015 (UTC)
replies: text: Unfortunately, you got it wrong. Read again: Storage is not the point (although, of course, it would be nice not to have your data vanish in a black hole at the end of the channel,right?). My passage is about data copying or moving. Data transmission either local or remote is at the heart of copy operations (or how would you go about it?). It appears crucial to me to make that point somewhere. -- Kku 07:56, 14 January 2016 (UTC)
replies: text: It's true that data copying/moving involves data transmission, but that observation does not seem useful in this article, particularly in the lead. Let's see if anyone else wants to comment. Johnuniq (talk) 09:43, 14 January 2016 (UTC)

message: has broadened the stated scope in the lead to include data communication and data reception. Data communication already redirects here and I can't identify a better place to send it. There is no Data reception redirect or article and perhaps there should be. If we're going to broaden the scope like this, I think we need to consider moving the whole article to Data communication. ~Kvng (talk) 14:40, 25 September 2020 (UTC)
replies: text: Agreed; there ain't transmission without reception implied, hence communication; I can do the renaming if no one objects. 15:43, 25 September 2020 (UTC)

thread_title:  data communication 

message: The article opens with "digital communication", but data communication is not necessarily digital; as people also communicate with analog or organic methods. I feel if the purpose of this article is to discuss digital communication, maybe the title could be moved to "digital data communication", or the article could be expanded to focus on not just digital communications? 2A00:23C4:41A:9601:82C:F5C4:ABF7:DF82 (talk) 15:45, 16 April 2022 (UTC)
replies: text: Thinking too, in that context the word "information" can better apply, but "data" in isolation is still ambiguous.  2A00:23C4:41A:9601:82C:F5C4:ABF7:DF82 (talk) 15:49, 16 April 2022 (UTC)
