Data is often stored in external files for several key reasons:
- Memory Usage: Storing data in files frees up valuable RAM. Programs can be large, and storing all data in memory would be expensive and potentially lead to performance issues, especially on devices with limited memory. Files allow for storing large datasets that don't need to be actively accessed all the time.
- Data Persistence: Data stored on a storage device (like a hard drive or SSD) persists even when the program is closed or the computer is turned off. This is crucial for applications that need to retain information between sessions, such as databases, documents, and settings. Data stored in memory is volatile and lost when power is lost.
- Program Flexibility: External files allow programs to be more modular and adaptable. Data can be updated or modified independently of the program's code. Different programs can also access the same data file, promoting data sharing and reusability. This separation of data and code makes maintenance and updates easier.
In summary, using external files provides a more efficient, persistent, and flexible way to manage data compared to storing it solely in a program's memory.
