        !             8: In the context of  computing, random access means that an entity,
        !             9: such as  memory, can be  accessed at any  point, not just  at the
        !            10: beginning.  This  means that all points within  memory can be ac-
        !            11: cessed equally  quickly.  This contrasts  with sequential access,
        !            12: in which entities must be accessed in a particular order, so that

        !            16: the order  in which  data are  read is dictated  by the  order in
        !            17: which they stream past the tape head.  Random-access memory (RAM)
        !            18: is an example of random access.  Hard disks and floppy disks com-

        !            21: RAM, which usually consists of semiconductor integrated circuits,
        !            22: is also strictly random access.  In this regard, the term ``RAM''
        !            23: is   slightly  misleading;   a  more   accurate  name   would  be
        !            24: ``read/write  memory'',  to contrast  RAM  with read-only  memory
        !            25: (ROM), which is also random access memory.
