While we have been using a CD to work around the office and to install software etc the next generation CD which is not a CD in fact is called a DVD. DVD is an abbreviation for digital video disk and it is replacing the CDs that we have used for so long. This is typical of all technology that whenever we require a next generation product in a certain area and it is given to us the previous model goes obsolete and is replaced within a few years. Some models are successful while others are not that successful. The success of a particular newer technology actually depends on how much there was room for improvement. In the case of CDs one major draw back was the limited storage capacity and the second feature of the CD that was improved or eliminated in a DVD was that it was damaged because of scratching or consent contact to fingers and dirt etc which can not be avoided when handling such a component.
The DVDs are serving the very same function that CDs used to serve but they are better than the CDs. If you look at both the CD and the DVD they look exactly the same but the only difference is in their make and function to some extent. It would not be wrong to say that a DVD is a better CD version. It was in 1993 that the decision of developing two storage mediums was floated and Philips and Sony were supporting the compact disk or CD. Several other companies like Toshiba, Thomson, Pioneer and Time Warner etc were ruling for the super density disk. At this point third parties intervened to join both camps and make them agree on a single standard. It was Philips and Sony side that gave up their support of compact discs and fully agreed on the superior function of the super density disc which was the first form of a DVD. However, both these companies made a significant contribution to the pool which was making the DVD less prone to scratches and finger print damage etc.
Just like CDs there are two primary types of a DVD. One type of the DVD is writable DVD that allows for a single time operation on the DVD and this means writing operation. Reading can be done again and again but no changes in terms of writing on the DVD will be allowed. The second type available is the re writable DVD which allows for removing the once written data and replacing it with more data if you want. Reading can again be done several times on the re writable DVD. DVD recorder is used to write on a DVD and these DVD recorders also have the capability of reading off a DVD. Most computers that are being released in newer models come with a DVD player. DVD players are fitted in new models because DVD is the newer form of CD and will soon become commonly used and replace CD. DVD decoder software can be downloaded from the internet if there is need for running a DVD and you are unable to do that.
There are car DVD players available too and as the capacity of storage is more in the DVDs they are being preferred over the CD. The portable DVD is now available in movie shops, music shops and software are also coming on DVDs. The price of a DVD is slightly higher than that of a CD. There are portable DVD players that are used when you are away from home and require using a DVD. A portable DVD player should come in handy if you are traveling to a place where you know you may not have access to a DVD player.
