Random Access

Random access is generally known as direct access. Random access is the capability to have access to any item from a given population of elements at random. Sequential access is the direct opposite of random access. In random access, the elements can be retrieved irrespective of the location. In order to move from point A to Z,  you can just jump to point Z in random access system. The disk is an example of random access.
