There was a time when VHS tapes and the VCR's were the most popular form of home entertainment. Then the CD revolution took over that was fairly advanced in comparison to the former and the change was radical and it was instrumental in improving the whole experience of enjoying your favourite movie/music. This change has suddenly been replaced by a far more better technology that is known as the technology of DVD that is quite prevalent in the modern times.

The usual question which arises in such an argument is that what makes DVD's better than Cd's? Well, to understand the difference, we will have to find out the difference between the two technologies. Talking about the CD or compact disk, it is fairly portable rounded polymer that is used to record, store and playing video, text or audio. The quality is much more improved as compared to the VHS technology. These Cds have replaced tape cartridges and they are widely used in households or cars. Previously, read only Cd's were made but now these are replaced with a better technology that allows these music CD to record as well.

Coming to the DVD's (digital versatile disc or digital video disc), these are the better version of the popular CD's, and the benefit of DVD over CD is that they can easily store more amount of information in the same space. Like a DVD can easily contain 3 to 4 movies in comparison to a CD that cannot even hold a single movie in it. It is an optical disc for storing movies/data and it can hold information up to 4.7 GB than the ordinary CD that can hold up the data up till 700 MB. Further, CD's can only be used on one side, whereas, DVD can be recorded at both sides and it can also record in dual layers. Also, all the DVD drives are able to read a CD but it cannot happen in the case of CD's. Thus DVD is certainly a better and far more advanced technology in comparison to CD and thus is gaining popularity amongst the worldwide consumers.
