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[1],[2].
Pour calculer le bit-time, on procède comme suit :
bit time = 1 / -(débit binaire)^3
Avec une carte réseau ayant un débit de 10 Mbit/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.
