                              Q:
                           
                           
                                                      | A) Sequential access | B) Direct access | 
| C) Both A & B | D) None of the above | 
                              Answer:   C) Both A & B
                              
                                                            
                              
Explanation:
                               
                           
                           Explanation:
A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots, and sectors. Hard disks, zip disks, and floppy disks are common examples of magnetic disks.
 
        
Hence, Magnetic disks are the most popular medium for both Direct access and Sequential access.
