Bit time

Bit time

Le bit-time' est une notion informatique qui désigne le temps mis pour transmettre un bit depuis une carte réseau sur un câble.

Pour calculer le bit-time, on procède comme suit :

        bit time = 1 / Débit de la carte réseau

Avec une carte réseau ayant un débit de 10Mbit/s, le calcul du bit-time sera :

        bit time = 1 / (10 * 10^6)
                 = 10^-7
                 = 100 * 10^-9
                 = 100 nanosecondes

Un bit sera transféré par la carte réseau toutes les 100 nanosecondes
