What were used before floppy disks?
There are many advantages to using hard disks over floppy disks. Hard disks simply hold a greater amount of information, which is very important today as many files are larger than those used in the past. Hard disks are also more durable than floppy disks, floppy disks are easily destroyed by accidental bending or spills.
Floppy disks are still used in a variety of machines (not desktop computers) that were built for years after the floppy was introduced. These machines (such as embroidery machines, machine tool devices, pianos, and some medical equipment) were built to last decades and are still in use. Floppy disks are also used for art projects and promotional purposes. For a great example, check out www.nickgentry.com.
The floppy disk stores data. Before the days of large hard drives, flash disks, cds, and dvds this was the primary media for transporting data. For example if you wanted to install the old Windows 3.1x it came on a bundle of floppy disks. If you wanted to take a project from work or school back home, you used a floppy disk.
You would need 729 floppy disks to hold 1GB of data. This is because: 1 gigabyte is equal to 1,073,741,824 bytes 1 floppy disk can hold 1,474,560 bytes So floppy disks per gigabyte is equal to 1,073,741,824 divided by 1,474,560, which is 728.18 disks. This means you would need 729 disks to hold the full 1GB.
