But as the time passed and the technology advanced bringing much more new valuable stuff, there echoed a voice, more or less a chaos, “You have insufficient memory!”. Memory management had many issues that different researchers came across but above all is the memory size that fills up within no time and we are again in search of more memory to store our data which we can’t afford to lose.
