What is Disc?
Discs are those flat and round-shaped objects which somewhat look like frisbees. They were popularly used until the launch of pen drives or the online streaming platforms that exist now having this wide range of variety of media content. Discs, in general, are really thin and have a hole in between. They are made out of metal and glass. The primary use of discs was to store media. This included movies, songs, and video clips or recordings taken on camera. They are popularly also called DVDs and CDs.
These DVDs and CDs can be inserted into TVs, computers, mini players, CD players, DVD players, etc. They can also be effortlessly removed from the computers or other devices that have once been done playing. They are all mostly available in a read-only format, which means they cannot be rewritten.
The ROM files are the ones that cannot be rewritten. However, there are some exceptions in such a case. They can be rewritten but just once or multiple times.

Disk refers to the magnetic medium or magnetic storage device. These are popularly very similar to floppy disks or hard drives. Its origin is also related to these two terms.

All disks available are, in general rewritable. However, they cannot be rewritten if the owner or administrator has locked them, in which case they are read-only.
The hard drives on the computer are the kind of discs that can be partitioned into further smaller volumes. Hard drives cannot be removed from the computer. But, the external hard drives or floppy disks can be easily removed. The floppy disks are usually 3 to 5 inches long and are placed in the disk drives. The disk is a term that is popularly used in the computer language lingo rather than a common man’s language. The rise in the use of personal computers gave rise to an increase in awareness about the difference between discs and disks. Some consider it the same as discs.
