Thread: DISC and DISK

Hi everyone. I am not computer savvy. I have little bit knowledge of computer. I want to know about difference between disk and disc. If anybody knows any info then please let me know that. Thanks in advanced.

Discs
a disc is a optical media, like an audio CD, CD-ROM, DVD-ROM, DVD-RAM, or DVD-Video disc. Some discs are read-only (ROM), others permit you to burn content (write files) to the disc once (like a CD-R or DVD-R, unless you do a multisession burn), and a few can be erased and rewritten over many times (like CD-RW, DVD-RW, and DVD-RAM discs).

All discs are removable, meaning when you unmount or eject the disc from your desktop or Finder; it physically appears of your PC.

Disks
a disk is a magnetic media, like a floppy disk, the disk in your computer's HDD, an external HDD. Disks are always rewritable unless purposely locked or write-protected. You can simply partition a disk into some smaller volumes, too.

Disks are usually conserved inside a metal or plastic casing (often, a disk and its enclosing mechanism are together known as a "hard drive").
