Information stored in memory may be retrieved using either the sequential access technique or the direct access method. You can get there using any of those methods, and both work. Why is it beneficial to have immediate access to cutting-edge tech and how might this be accomplished? How will we be able to update the data previously entered into a device if it only allows direct access through sequential access?
