Abstract

Un sistema visual de datos que comprende una central controlada por computador la cual, en un diálogo con los usuarios conectados con la misma a través de una red de telecomunicación, suministra información a dichos usuarios, es capaz de recibir información de proveedores de información conectados a la misma y contiene dispositivos de memoria de gran capacidad para almacenar la información que ha de suministrarse, caracterizada porque la central controlada por computador tiene, a un nivel centralizado, varias unidades funcionales independientes (ZIE, ZTE, ZUE), que controlan las secuencias de operaciones iniciadas en la central y, por lo menos, un nivel periférico, un número de unidades de control de comunicaciones (AE-FE/D, AE-DPV) que controlan las secuencias de operaciones iniciadas a través de la red de telecomunicación, pudiendo dichos número fijarse según el número de usuarios.
