                 In your previous classes, you have learnt about tables, addition, subtraction, etc. It was

                 your memory that saved all the information for you in your memory which acted as a
                 storage device.

                 Similarly, computers also have memory to store all the data and instructions for performing
                 various tasks and functions. Let us learn what is memory and its function.


                      MEMORY


                 The storage space in a computer is called its memory. The data and instructions that are
                 entered into the computer using input devices are stored inside the memory. There are two
                 types of memory: primary memory and secondary memory.
