DVD’s provide more information compared to CD’s, and CD’s are commonly used for audio and program files. At the same time, DVD’s are used for video program files. CD’s and DVD’s have become a common technology, as both can be referred to as compact discs.
However, CD’s and DVD’s each have their unique purpose. CD is an optical disc that is employed to store data. These are made to replace floppy discs that were used to store files and programs from the computer. CD’s caused the floppy disc to become irrelevant, and CD’s will typically hold up to 80 minutes of audio. DVD’s are like CD’s and are also an optical disc storage device.
These were created separately by Philips, Sony, Toshiba, and Panasonic. Before this, video and film were being recorded on video CDs. Gradually, other formats became available, including Multimedia Compact Disc and Super Density Disc. The disparity in formats caused the companies to come together and set up a standard for maintaining one type of format, culminating in DVDs. As prices of DVD decreased, it caused VHS tapes to become outdated and no longer in demand.
CD or Compact Disk and DVD or Digital Versatile Disc are both optical media used to store digital data. Out of the two, DVD is a more recent technology compared to CD. It was released into the market as an improved version of CD, just as how CD was introduced to replace cassette tapes. In terms of capacity, a standard DVD has more capacity compared to a CD. While a CD can store data with a maximum capacity of 700 MB, a standard DVD can store up to 4.7 GB of data. This explains why people always go for DVDs, particularly when they need to store more data into a single disc. Although there was a time when CDs were the only media for storing programs, software, and movies, people now prefer DVDs to CDs because of the higher compatibility of DVDs for stories movies, and programs. Unlike CD players, DVD players can play both CDs and DVDs.
One of the ways to differentiate between CD or Compact Disc and DVD or Digital Versatile Disc is by comparing the capacities of the two. CD was developed to replace and improve on some of the limitations of the old cassette tapes. A CD has the maximum capacity of storing up to 700MB of data. It can also hold video data with a maximum length of 60 minutes. On the other hand, DVD is a more recent technology compared to CD. It has more storage capacity compared to the CD. For instance, A DVD can hold up to 17GB of data. As you would expect, DVDs have enough space to store more information compared to CDs. Although there is no difference when you compare the audio capabilities, however, CDs are less preferred for software programs and video. This is because you will only need a single DVD to store data that would have required you to use two CDs.
A DVD is also known as Digital Versatile Disc. This is similar to a CD in the sense that you can get data from it. One difference between the two is that DVDs will have the ability to store more data as compared to CD. Take note that there are different types of DVDs and CDs. For example, when you say CD R, this means that you can only place data on it once. When you say CD RW, this means that you can overwrite the data that you have already placed. For the DVD, DVD R can only be placed with data once while DVD RW can be rewritten with different types of data all over and over again. If you would choose to change the information numerous times, it will be up to you.

There was a time when CDs and DVDs were very popular. One of the major differences between the two is their capacity. When you say CD, it will only have the capacity to store up to 700 MB while the DVD will have the capacity to save different media files up to 4.7GB.
This means that if you would like to store more files, you should obviously choose the DVD over the CD. This explains why there are some DVDs that contain a lot of movies. Another thing that can be different between the two is the speed by which data will be placed on them. It will be faster to store files on the DVD too as compared to the CD.
