For most people born before the 90's, a "3 1/2 inch floppy" was once a crucial part of their technological lives; securing and transporting important files and data. Of course nowadays, the 1.44 MB storage space is far from adequate and no new computers come equipped with an appropriate drive for the disks. Little surprise then that the majority of children today have no idea what one is (despite the fact that ubiquitous software such as Word and Excel still use a floppy disk symbol for their 'save' buttons).
As a recent survey
by YouGov has shown, 67 percent of the 6 to 18 year olds in the UK
don't know what a floppy disk is. Other essentially obsolete tech such as overhead projectors (once present in almost every classroom), and pagers were recognised even less.
