                         MEMORY


                  The storage space in a computer is called 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 given by the user                  RAM
                  and also the results produced by the computer temporarily.
