A hard disk is the physical medium information storage device of most computerized systems. It is an actual disk that rotates at high speed. The surface is coated with magnetic material, and data is stored magnetically on the surface. A tiny read/write head on the end of an arm that can move over the surface of the disk does the reading and writing to transfer the information to and from the medium.

A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.

File handling is simply the process of opening, reading, writing and closing files. Files are simply streams for input and output, or the "serialisation" of objects. In other words, reading and writing data to and from disk storage.
It doesn't really control anything, rather it flashes on whenever there is hard disk activity (i.e. reading from or writing to the disk)
Sequential access refers to reading and writing dataæconsecutively. For instance, like a hard disk or compact disc, the information can only be used in the same order it was created.
