Digital storage of information and knowledge is becoming common due to the internet. While there are certain drawbacks, they are outweighed by the benefits.
One downside of storing information online is the spread of misinformation. When information is stored in a particular website, it is easy to edit it while downloading or copying. Wikipedia can be a good case in point, where users can alter information without any restrictions. Because of this, it is considered an unreliable source of information. The reliance on technology is another disadvantage. Using and storing information becomes impossible unless(if not) there is stable internet connection, not to mention viruses and other malware. Readers do not usually face such problems with physical books.
Despite these disadvantages, the advantages are far greater. One major benefit of digital storage is the accessibility of information. This means that people can use information at their own convenience regardless of their geographical location. For example, students preparing for exams can make use of materials unavailable in their local libraries. The fact that online libraries offer unlimited copies of books can be a further advantage. Physical libraries are inferior(=weak) in this respect as they usually have limited number of materials. So, if a library runs out of a particular book, it can be impossible for other people to access it; however, with the internet, this is not the case.
In conclusion, although there are some disadvantages to keeping information and knowledge on the internet, they are not as significant as the advantages.
