Computer systems always have small RAM, yet it mostly has a large secondary memory like hard disk? Why? The access time of a hard disk is much larger than RAM, even than RAM is smaller in size than hard disk. Justify.

RAM is the memory where your programs load when they are running, loading a program needs less space but faster access time, that is the reason RAM is small. RAM cannot be used to store data permanently.
While as hard disk is where you store files, it does not has to be fast but needs to be larger in size so as to store the data.
