to cassettes used for music. A tape is serial in nature, which
means that in order to get to any given part of it, you first have
to go through all the parts in between. A disk can be accessed
randomly, i.e., you can jump directly to any place on the disk.
The serial access of tapes makes them slow.</P
><P
>On the other hand, tapes are relatively cheap to make,
since they do not need to be fast. They can also easily be made
quite long, and can therefore contain a large amount of data. This
makes tapes very suitable for things like archiving and backups,
which do not require large speeds, but benefit from
low costs and large storage capacities.</P
