For my college assignment, one of the question asks to explain how a computer increases its memory in machine cycle. I have searched and so far I have found that a computer can't increase it's own memory. Can anybody explain this to me?
Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
I'm not sure I fully understand what your question is but I suspect your assignment is trying to teach you about paging.
Paging doesn't actually increase the amount of physical memory the computer has. It achieves the effect of 'increasing' the amount of memory available to programs by moving chunks of memory that aren't immediately being used to some form of secondary storage. This frees up memory to be used by other programs. When the data that was swapped out is needed again, it's read from secondary storage into memory.
Typically, paging is used in conjunction with virtual memory.
