GoKawiilRetro-tech explainer revisits IBM's Token Ring networking standard
A technology retrospective recounts the history of Token Ring, the IBM-backed networking standard introduced on October 15, 1985, which competed with Ethernet through the 1980s and 1990s. The piece explains that while Token Ring avoided collisions by passing a single token between systems and handled network saturation well, it required all cards to run at the same speed and was ultimately outcompeted by cheaper, open-standard Ethernet equipment.
