    Hi to all.

    I got a doubt while I'm executing my program in ALP.
    it may be silly but though you should think for a while......
    Why can't we execute the problems in secondary memory😕
    what is the one that mainly differs secondary memory from main memory such that we should bring the data (what ever it be) to the main memory for processing😕


    This is my doubt and waiting for replies....

    hi friend,

    according to me...

    we caanot execute the program in secondary memory and we need to bring the program code in main memory because today's processor's are very fast they work at gigahertz and to keep it up with it's performance we need memory which is faster enough so that the delay in read & write operation's doe's not affect the performance of processor.there is always's delay due to latency in secondary memory & also their transfer rate is low.

    so as the main memory is much faster than secondary memory program's need to be brought in main memory to keep up with processor's performance.

    today there is also cache memory available which is much fater than ram & this memory is kept close to the processor.
    Are you sure? This action cannot be undone.
