El documento describe las características de varias tecnologías Ethernet antiguas como 10BASE5, 10BASE2 y 10BASE-T, incluyendo sus parámetros de temporización, formato de trama y procesos de transmisión. También discute las implementaciones posteriores de Fast Ethernet como 100BASE-TX y 100BASE-FX, así como Gigabit Ethernet 1000BASE-T.
