Em uma rede Token Ring, os dispositivos s\u00e3o conectados em um anel f\u00edsico e a transmiss\u00e3o de dados \u00e9 coordenada por meio de um pequeno pacote, denominado token, que circula pelo anel.<\/p>\n<h2>A hist\u00f3ria da origem da rede Token Ring e a primeira men\u00e7\u00e3o dela<\/h2>\n<p>O conceito de Token Ring foi introduzido e padronizado pela primeira vez pelo IEEE no padr\u00e3o 802.5.
