To (most)non-PC devices, a CD holds music and a DVD holds videos. Again, the only difference is how much you can put on them. They each hold data, just like a hard drive, SD card, of floppy disk, so you can put what ever you want on them. If you are using them with a computer, there are pretty much interchangeable in terms of “what you can do”. In the early days it was only possible to read from the disks but technology soon allowed consumers to write to these also.
