'downloader' originates from the English word 'download', where 'down-' meant 'from a higher to a lower place' and 'load' meant 'to put a large quantity of something into a vehicle or container'.

'download' changed from the combination of 'down' and 'load' in English and eventually became the modern English word 'downloader'.

Initially, it meant 'to transfer data from a central system to a local system', but over time it evolved into its current meaning of 'a person or software that performs this action'.
