Hi, This question may sound stupid. But I want to know that
if the secondary storage device is used to store data on
computer, then what is the use of the primary storage in the
first place? Why cant we use only one?

Answer Posted / sandeep
time taken to access primary memory(RAM) is faster than to
access secondary storage memory which influences ur
processor speed/throughput.
primary memory is like scratchpad where data related to
currently executing programs is stored, rest is stored in
secondary storage device, accessed only when required.
