Anotações e citações/ texto breve:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Before the advent of electronic computers, data processing was performed using electromechanical devices called unit record equipment, electric accounting machines or tabulating machines. Unit record machines were as ubiquitous in industry and government in the first half of the twentieth century as computers became in the second half. They allowed large volume, sophisticated, data-processing tasks to be accomplished long before modern computers were invented. This data processing was accomplished by processing decks of punched cards through various unit record machines in a carefully choreographed progression.
