The digital compact disc, now commonplace in stereos and computers, was invented in the late 1960s by James T. Russell. The first floppy was made by IBM around 1970 (this was an 8" floppy). The 5 1/4" floppy was introduced in 1976 and Sony pioneered the 3 1/2 floppy with a hard shell in 1981.

It is True cause ibm OWNES Actually, it was Invented by Yoshiro Nakamatsu in the 1970's but he licensed the patents to Sony so gets no credit for inventing the basic technology.

A CD is round and you can watch stuff on it and can record stuff on it. A floppy a downloading thingy.

DVD - 4.7GB CD-RW - 60MB CD-R - 700MB 'Floppy' - unspecified. Typical PC floppy disk is 1.44MB, highest recorded capacity for a floppy disk variant is 200MB. Out of the above, the DVD holds the most by far.

A CD-R or CD+R (700 MB) = 486 floppy disks = 699.84 MB

A CD can hold the equivalent of approximately 486 1.44 MB floppy disks.

A cD holds 600 times more than a floppy disc.

The computer floppy disk was invented in the United States.

to do this you must first save what ever is on the floppy disc onto your computer or laptop and then transfer the file from the floppy on to an empty CD disc and then it is done


You can copy 464 floppy's on a CD

IBM invented the floppy disk back in the 70's.IBM in the 1971

put the files on a CD...

Data can be copied to CDs (Compact Discs) which are writable/rewritable and need a CD/DVD burner to write data. The difference between a floppy and CD is that floppy is a magnetics media and CD an optical media (read/write happens with help of a laser light). - Neeraj Sharma

No, the floppy disk was really square and floppy. It was the original storage for the earliest PCs. Later there was a "floppy disk" that was smaller and hard. After that the round and hard CD.

Yes. A typical CD holds about 700MB whereas a 3.5 inch floppy disk only holds about 2MB.

Floppy drives are identified by drive letters A and B. To change between them, simply enter CD A: or CD B:

The CD was invented in 2001 Thomas clamps invented it.

There are a number of differences between CD and floppy discs. Floppy discs are magnetic and use magnetism to store data, CD drives are optical and read pits in a reflective surface using a laser. CD's have a much higher data density than floppy discs. CD's are a much higher capacity and can be read at much higher speeds than floppy discs.

a recorder was invented before a CDplayer or CD

The floppy disc drive was invented at IBM in 1967. It used 8" floppy discs. The first floppy disc drive in an IBM personal computer appeared in 1981. By this time the original 8" floppy disc had been replace by a 5.25" disc.

Sony invented the 3.5 inch floppy disk and first sold it in 1980. ########################################################## The earliest floppy disks,WAS invented at IBM, and were 8 inches in diameter. They became commercially available in 1971.

No because a floppy drive is rewritable, as CD-R's are not. You should invest in a CD-RW (ReWritable) or a USB Disk Drive (Come in a ll sizes from 64MB - 1 TB)

Floppy drives are small and have less space to store information and they break easily. nowdays hardly some pc's have floppy drives. while cd-rom have more storage space, they are tough to break and all pc's hav cd-rom drives
