Conclusion

To summarize the given topic, this can be concluded that CD-R and CD-ROM both are exactly similar when viewed generally.

A common person cannot state the difference between the two but still be similar through their appearances.

They both are different based on their use.

CD-R or CD is the most common device that is now available in the market, and anyone can purchase it because of its very affordable price range.

These compact discs give their user the power to store different kinds of data in them.

But the condition here is that the data, once stored, cannot be deleted or vanished. Despite this, one could add more data until the memory is full.

In contrast to this, CD-ROM is another device that is available in the market and is comparably expensive. The CD-ROM is only played by inserting it into the CD-ROM device.

Perhaps this device allows the user only to view the pre-stored data in the compact disc.
