This differs from the
primary memory in that; it is not directly accessed by the CPU. The CPU uses
its input-output channels to access the memory. Data transfers from the
secondary memory uses intermediate area in the primary memory. This memory is
non-volatile. It is implemented on hard disks. Access time is in the range of
milliseconds while it’s in terms of nanoseconds in the cache. Storage capacity
is also large; around 400GB at the moment. File systems are implemented on the
secondary memory.
The secondary memory
together with the primary memory is classified as Online Memory. This is
because they are controlled directly by the CPU.
