Abstract
UNA PROTECCION DE DATOS Y METODO PARA MANEJAR LOS ERRORES DURANTE LA COPIA DE DATOS DESDE UNA MEMORIA INTERMEDIA DE ESCRITURA DE PROTECCION DE DATOS HACIA UNA MEMORIA EXTERNA EN UN SISTEMA DE PROCESAMIENTO QUE INCLUYE UN PROCESADOR. CUANDO LOS DATOS SOLICITADOS POR EL PROCESADOR EN UN LUGAR DE ALMACENAMIENTO DIRIGIDO DE LA PROTECCION DE DATOS SON DATOS VALIDOS, MODIFICADOS, Y DISTINTOS DE LOS DATOS SOLICITADOS POR EL PROCESADOR, LOS DATOS SE TRANSFIEREN PRIMERO A LA MEMORIA INTERMEDIA DE ESCRITURA DE PROTECCION DE DATOS Y LUEGO SE REGISTRAN EN LA MEMORIA EXTERNA DESPUES DE QUE LOS DATOS SOLICITADOS HAYAN SIDO EXTRAIDOS DE LA LINEA COMUN DE MEMORIA. SI SE PRODUCE CUALQUIER ERROR DURANTE LA COPIA DE LOS DATOS DESDE LA MEMORIA INTERMEDIA A LA MEMORIA EXTERNA, LOS DATOS SE TRANSFIEREN DESDE LA MEMORIA INTERMEDIA AL LUGAR DE ALMACENAMIENTO DE LA PROTECCION DE DATOS A LA QUE ORIGINARIAMENTE SE HABIA DIRIGIDO EL PROCESADOR ANTES DE QUE LA LINEA DE MEMORIA SEA DESCONECTADA.
