How file stored in a computer hard drive


Discussion:

Q: In spite of the fact that sequential files lack direct (targeted) addressing of each of the records and fields (e.g., you cannot easily read/replace the only record with the number 28 from 50 records in the file), they are the most widely used. Why? Is their mode of operation different from the one used for the files stored on your computer's hard drive?
