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.
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.
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.
Used Cds And Dvds
As a rule, optical discs -- CDs, CD-ROMs, CD-Rs, CD-RWs, and the many variants of DVDs -- are much more durable than some other types of data storage, such as floppy disks. In fact, the first batch of audio CDs produced in 1980 are claimed to last for 100 years (for more on the history of CDs, visit this page).
However, this doesn't mean that you're free to abuse your optical discs. Improper handling and usage leads to scratched, broken, or dirty discs. As the damage accrues, your discs become simply unreadable. Chances are you already know the run-of-the-mill tips regarding taking care of your CDs and DVDs. Some of these are:
1) Keep your discs away from medium to direct sunlight for an extended length of time.
2) Protect the underside (the "signal side") of the disc from scratches, dust, dirt, stains, water, and finger prints.
3) To clean your discs, gently wipe the underside with soft, dry cloth. Wipe starting from the inside hole to the rim in a straight motion. Do not wipe the disc in a circular motion.
If you've taken these precautions and still your discs fail in one way or another, then you can attribute it to uncertainty -- the culprit might be substandard manufacturing processes, or the varying materials used by different disc manufacturers.
For CDs and DVDs that you have burned yourself, there are some additional things that you'll need to take note of. First, know that manufactured discs are more durable than recorded ones, especially those that you did at home. This can be attributed to the different ways that the data is recorded for these discs -- manufactured CDs and DVDs have data literally pressed onto them, while recordable ones use dyes that change color or reflectivity under the heat of a laser.
Also remember that burning CDs and DVDs at high speeds (such as 52X) result in less dependable discs. The way to go is the middle speeds (e.g. 24X); as they always say, everything in moderation, and this is true in burning discs.
After you've burned your CDs and DVDs, the next step you often take is to label them, usually with marking pens. One word: DON'T. These can slowly seep into the dye layers and damage the data. As an alternative, you can write on the transparent area in the disc's center (there's no data recorded there).
