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.

The whole point was that cs/ma (check if anyone is talking while you're talking) was a competing strategy to token ring (everyone can talk in their turn).

You could lose most of your bandwidth under contention with csma, it scaled poorly and routers/switches were crazy expensive because they needed to have memory to buffer packets at full flow.

Somebody made an integrated switch ASIC and the price plummeted and suddenly every network was switched.
