When was the floppy disk intoduced?
The original floppy was an 8 inch, single sided disk first developed in the late 1960's as a result of research efforts by IBM. The first floppy disk drive systems became commercially available in 1971. They cost more than a new PC costs today.The floppy disk was introduced in the 1970's, and it revolutionized data storage in the PC. It ran strongly for some time, but faded in the 1990's. It is rare to see a working machine being used in this day and age with a floppy drive in it. Wikipedia has more information, and you'll find a link to their post just down the page below this answer.1971According to wikipedia; IBM introduced 8-inch floppy disk (read-only) in 1971...

What is the DOS command used to copy ALL of the files on one floppy disk to memory and then copy that same information to multiple other floppy diskettes with one command?
DISKCOPY is the command to copy all of the files to memory and then copy those files to another disk. Unfortunately, it does not copy to multiple disks. Here is the syntax: DISKCOPY [drive1: [drive2:]] [/1] [/V] [/M] /1 Copies only the first side of the disk. /V Verifies that the information is copied correctly. /M Force multi-pass copy using memory only.
