For those of us old-timers who muscled 9-track tapes on 10 ft tall Burroughs B-3500 mainframe computer tape drives, with a total storage capacity of about 5 kilobytes, the idea of sticking a 64 gigabyte SD memory chip into my laptop computer is pretty cosmic.

Terms like PCAM (punch card adding machines) are no longer part of the taxonomy of information technology, nor would any young person in the industry comprehend the idea of a disk platter or disk pack.

Skipping a bit ahead, we find a time when you could purchase an IBM "XT" computer with an integrated 10 megabyte hard drive. No more reliance on 5.25" or later 3.5" floppy disks. Hard drives evolved to the point "Fryes" will pitch you a USB or home network 1 terabyte drive for about $100.
