                 In your previous classes, you have learnt about mathematical tables, addition, subtraction,

                 etc. It was your memory that saves all the information for you and acts 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 computer memory is and about 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.

                 Primary Memory

                 This is the main memory of a computer. CPU can directly access this memory. It is fixed on the

                 motherboard of a computer. Primary memory is further divided into two types:

                 1.  Random Access Memory (RAM)

                 2.  Read Only Memory (ROM)

                 Random Access Memory (RAM)
                 RAM is a temporary  memory. The information stored in this

                 memory  is lost when the computer is turned off. That’s why it
                 is  also  called  volatile memory.  It  stores data  and  instructions                 RAM
                 given by the user and also the results produced by the computer

                 temporarily.
