A computer has a memory hierarchy, rather than just a single memory component. The lowest level is some form of secondary storage such as a magnetic disk. The next level is the main memory where a subset of the data from the hard disk is stored temporarily. The cache memory is the next level and uses SRAM to store frequently used data. Finally, the register store variables and temporary results for the current CPU computations.
