How to treat data communication questions?

+8
−0

This question here about the OSI model was closed as off-topic. How should we treat questions about data communication?

What is definitely on-topic here:

  • Embedded systems programming, including microcontrollers and FPGA.
  • Specific software or hardware questions about industry standard buses like SPI, I2C, UART etc.
  • Hardware questions about fibre optics, copper wiring, connectors.

What might be borderland on-topic (and possibly overlap with other Codidact sites):

  • Abstract data communication questions.
  • Data communication protocol specifications.
  • Higher layer questions regarding LAN or Wifi networks.
  • The Internet protocol suite.

I agree that the particular question was correctly closed. Questions about protocol stacks aren't necessarily off topic. However, this one was because nothing about it had anything to do with electronics or low level embedded systems.


Where should I ask it then?

I don't know. That's not our problem here. Of the Codidact sites, the only one where it has a chance of being on-topic is Software Development as far as I can tell. You'd have to read their help carefully to check that yourself before posting.

I disagree, since the OSI model is fundamental to any data communication. For example I often find myself in discussions where people ask how to send data over CAN bus or UART. Then I have to explain that how to send data isn't covered by CAN or UART, since they only specify physical and data link layers but how to send data across it is covered by higher layers. This assuming that they know about the OSI model - which (assuming a half-decent university) is taught to all electrical or computer engineering students. And something which is taught to all electrical engineering students ought to be on-topic here.
