A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Sending intranet Email on a token ring network still used the same process as creating a Memo (lemmy.world)

Please correct me if I'm wrong, might have breathed in too many soap fumes.

Token Ring sends the packets to every node by passing it from one node and if that node is not the recipient it passes it on to the next node.

Memos were created the day before with a list of recipients then it was passed around till everyone on the list had read it.

Yeah, see the pic in the thread. The "switch" (MAU, Media Access Unit) seems redundant to me though, based on what I read I would expect the network interface cards to create a functional ring on their own over a shared medium. Maybe the old cards for ring-topology networks only worked in that one mode and the MAU made them compatible by pretending they were part of a physical ring, cutting computers out of it if they turned off.

Yes, I think that's probably how it worked.
