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 may be a little bit biased on this one because it was my question which started this thread but :

I don't think data communication question should be generally off-topic because it evolves binary logic and the way the data are sent/received is through electric signals.

Arguably data communications, internet protocol, etc. could be on-topic. But saying "evolves binary logic" and "electric signals" is not the reason. On that basis, any computer (up to a mainframe or entire data center) or electronic device that includes any binary logic (from a series of switches or relays up to and including any computer of any size) would be on-topic.
