The correct answer is 2. A hard disk is used to store large amounts of data. It is a non-volatile storage device that can be accessed quickly and is commonly used in computers and other electronic devices for long-term data storage. Hard disks have a much larger storage capacity compared to floppy disks (discheta) and CDs, making them ideal for saving large quantities of data. Scanners, on the other hand, are used to convert physical documents or images into digital format and do not serve the purpose of data storage.
