   Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay-line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line. The first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it was volatile in that it had to be continuously refreshed, and thus was lost once power was removed. The earliest form of nonvolatile computer storage was the magnetic drum, invented in 1932 and used in the Ferranti Mark 1, the world’s first commercially available general-purpose electronic computer.

  • According to the text, before 1932, information could only be stored provisionally in digital form. 

    De acordo com o texto, antes de 1932, as informações só podiam ser armazenadas provisoriamente em formato digital.

    Interpretação chatinha, mas vamos lá:

    The first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it was volatile in that it had to be continuously refreshed, and thus was lost once power was removed.

    Então, era uma maneira provisória de guardar a informação naquela época, tendo em vista que se faltasse energia "and thus was lost once power was removed", a informação era perdida.
