give the examples of sequential access memory?
sequential access
Sequential data is what uses access. This is used in science.
Hierarchical Sequential Access Method-is a method to use sequential access of database.

To access a particular data item in a sequential file, you need to read in all items in the file prior to the item of interest. This works acceptably well for small data files of unstructured data, but for large, structured files, this process is time-consuming and wasteful. Sometimes, we need to access data in non-sequential ways. Files which allow non-sequential access are random access files.
Indexed-sequential file organization allows for efficient storage and retrieval of records by combining the benefits of sequential access (fast for batch processing) and direct access (quick for individual record retrieval). It provides faster access to records compared to purely sequential files while maintaining sequential organization for improved batch processing performance. The index allows for quick access to specific records without needing to search through the entire file.
