RE: "resurgence of parallel data links in RF communication", I think the serial vs. parallel distinction is clear for digital channels, but not for analog. If analog channels are included in this article, then I suggest making the distiction, and saying that analog channels could be considered parallel at the bits per symbol level (V.32 etc.), or at the carriers per channel level (ADSL), even though they are serial at the wire level.

I created this page to help the cleanup effort on Serial communications. I know there are no sources, but please be gentle -- this is my first "real" Wikipedia article. Any help would be appreciated! Bushing 07:17, 22 March 2006 (UTC)
I suggest merging parallel transmission into parallel communication. They are so very closely related that it is simpler to cover both in one article. -- 68.0.124.33 ( talk) 03:54, 30 May 2008 (UTC)
Wouldn't it make more sense to compare SCSI to SAS (Serial-Attached SCSI) than to a general purpose external interface like FireWire? FireWire is most directly comparable to USB rather than a generally disk interface. —Preceding unsigned comment added by ParticularG ( talk • contribs) 17:56, 8 July 2010 (UTC)
The basic difference between a parallel and a serial communication channel is the number of electrical conductors used at the physical layer to convey bits. Parallel communication implies more than one such conductor. — is this really true? Multi-lane serial links (with lanes in parallel) have grown very common: PCIe, Ethernet (1000BASE-T onward, multi-lane fiber), USB SuperSpeed+ 20G, Thunderbolt, ... Isn't the actual difference that a parallel channel uses a single, common clock for all signals while each serial (sub)channel has its own clock, usually embedded? Additionally, number of electrical conductors is highly misleading as most serial electrical interfaces use differential signaling over twisted pairs. What about fiber? -- Zac67 ( talk) 08:30, 25 October 2020 (UTC)
