CDs, also known as Compact Discs, are a simpler version of recording data and storing them whereas DVD is a complex form of the same. It is a kind of disk with a larger storage capacity and higher speed. It can store all kinds of films and computer data. The two are easily available in market at low prices. They are affordable to everyone today.
A number of differences set them apart. The first of them is the configuration of the disc. They are configured differently as a CD has fewer complications than a DVD. The most important is in respect to storage space. The CD has lesser amount of storage capacity as compared to a DVD. They are less reliable than DVDs. The movie watched at one go in a DVD can be recorded only in two to three CDs at a time.
The CD can be played in any first grade player but DVD needs a higher version of player. A DVD player can play a CD too. A computer can play normal CD but it cannot play a DVD directly. It needs a DVD ROM to play it. There are different technical processes to handle them.
If you think dope is for kicks and for thrills, you’re out of your mind. There are more kicks to be had in a good case of paralytic polio or by living in an iron lung. If you think you need stuff to play music or sing, you’re crazy. It can fix you so you can’t play nothing or sing nothing.
—Billie Holiday (1915–1959)
The cost of a CD is quite different from that of a DVD. The CD is available at a much lesser price than a DVD. They are available anywhere in the market today and even a stationery shop has a variety of them. There are a lot of brands with different prices.
DVD can be used at a specific place only. The CD can be made a multisession disc but a DVD is not used for the same purpose. DVD can be used to store a movie but generally not for minor works of office assistance. The CD can be viewed in DVD ROM but a DVD cannot be viewed without the same. The same is true for a DVD writer where a CD can be viewed as well as written.
Nowadays a CD is preferred for file work. That is for better and long duration as well as for convenience of storing. But for other purposes a DVD is far better. The reason for this is the number of sector tracks. The tracks are more in a DVD than in a CD. This is the main reason for differentiation between the two. The sound quality and picture in the two also have great variation. The DVD has these things in digital quality while a CD does not have any such features. The digital versions make the view clearer and more attractive. So we can say that a DVD is more entertaining than a DVD.
One way to think about play, is as the process of finding new combinations for known things—combinations that may yield new forms of expression, new inventions, new discoveries, and new solutions.... It’s exactly what children’s play seems to be about and explains why so many people have come to think that children’s play is so important a part of childhood—and beyond.
—Fred Rogers (20th century)
So you have seen the major differences between the two. They have their different uses at different places of work and their areas of work are quite different from each other as well.
