Beyond little microdots, the big difference between DVD's and CD's is storage Capacity. CD's (compact discs) can hold between 640 - 700 MB's (megabytes) of information on a single disc. DVD's (Digital Video Discs) can hold 4.7 GB (gigabytes) of information on a single layer disc, and 8.5 GB on a dual layer disc.
Beyond that, CD's hit the consumer market in 1983, and used a laser to read the media (disc) instead of magnetic technology. The standard amount of audio (time) on a CD with CDA sound files (compact disc audio) was approximately 72 minutes. Today, MP3 music files are about 1/10th the size of CDA audio. ***This unofficially works out to 10 MB per minute of audio with CDA, and 1 MB per minute of audio with MP3.***
Beyond all those specifications, there is an old technology called Laser Disc, which was almost the same size as an LP (the big ones) record, but also used laser. Based on the the technology that would bring us CD's, the laser disc provided more data storage than a typical CD due to more surface area to write to. This technology was short-lived vs VHS due to the high cost. Even though the discs themselves were cheaper to produce, the equipment required to play cost significantly more than equivalent VHS players.
In the future, HD DVD and Blue Ray technology will rerevolutionize laser technology. Future High Definition Television programs will be shown in 720p, 1080i or 1080p. These video qualities make watching Television as though it's photographic quality instead of dithered like current 480i. The capacity for HD DVD is about 35 GB's per dual layer disc, and Blue Ray is about 45-50 GB's per disc (unofficial specifications from respective Mfrs.)

∙ 14y ago== == The main difference between a CD and a DVD is amount of storage space.
A CD generally holds 700 MB and 80 minutes of sound (tracks, speech and the like).
A DVD generally holds 4.7 GB (Thats 4700 MB, and a singlelayer DVD. Doublelayered hold up to 8 GB, while doublesided and doublelayered DVDs hold up to 17 GB.)
They also use different types of readers (Disc drives). Most newer DVD drives are universal and can also play and write to normal CDs.

What is the difference between CD and DVD audio?
CDs play on two 16 bit 44.1 kHz channels and work on both DVD and CD players. DVD audio (DVD-A) requires a DVD player to work. It uses higher sample rates - up to 24 bit 192 kHz with stereo, but generally uses 24 bit 96 kHz - and can work on anything ranging from mono to 5.1 channels. That is not DVD-V. The difference is in terms of audio quality since the DVD-Audio format has 7 times more storage capacity then a regular CD-Audio. This means that you can actually hear the audio content on a DVD-Audio the best possible way ever since both the sample rate (192kHz) and the bit depth resolution (24bps) are higher then a regular CD-Audio (44.1kHz, 16bps) and would actually exceed the human hearing capability.

The file extension *.iso (hence inspiring the popular term ISO files/images/image files) refers to the ISO9660 filesystem that is used on CDs, DVDs, and most optical media. You can burn a physical CD/DVD with it provided you have CD/DVD burning software that can read ISO9660 images, and a CD or DVD writer drive. Otherwise, you can use it in place of a physical copy for some software that "requires" a CD/DVD to work.
