La primera referencia que se encuentra en la historia de un sistema de cálculo basado en un "aparato", es el ábaco, en el año 2500 a.C. en China. Ya entonces se utilizaban aparatos capaces de realizar cálculos. El aparato en cuestión era capaz de contar y almacenar datos (aparece el concepto de almacenaje y asociado a él el de memoria).
El sistema en cuestión está formado por varios ejes (que definen la capacidad de conteo de la máquina) y cada eje tiene varias cuentas o fichas, que sirven para representar los números del 0 al 9.
En el primer eje se representan las unidades, en el segundo las decenas, en el tercero las centenas, en el cuarto las unidades de millar etc.. (FGOM)
