Memory : Mainly Computer has two types of memory. i) Main or primary memory---High speed memory used to control the data input or output speed with the processor speed. Size of main memory is small. Cost is high.
ii) Secondary Memory : Speed of this memory is slow. But We can use a vest amount of secondary memory to story long size data. Cost of Secondary memory is low.
Example: main memory --- RAM / ROM (Random access memory / Read only memory )
