What are the serial access storage?

Serial access storage refers to a type of data storage where information is read and written in a sequential manner, meaning that data must be accessed in a specific order. This contrasts with random access storage, where data can be retrieved in any order. Examples of serial access storage include magnetic tapes and some types of optical storage, which are often used for backups and archiving due to their high capacity and cost-effectiveness. However, accessing specific data can be slower since the storage medium must move to the correct position sequentially.
