Get sample papers for all India entrance exams. In computing operations, secondary memory is accessed only by the primary or main memory and later transported to the processor. The CPU does not directly process it. A computer cannot run without the primary memory. When you "save" your document, the characters are copied to a file on the hard disk. T    Â. Primary memory is temporary. - Secondary Memory (Read-Only Memory, ROM) Primary Memory - main memory - holds program instructions and data for processing. This memory is also called permanent, external, stable or persistent memory. Auxiliary memory, also known as auxiliary storage, secondary storage, secondary memory or external memory, is a non-volatile memory (does not lose stored data when the device is powered down) that is not directly accessible by the CPU, because it is not accessed via the input/output channels (it is an external device). Secondary memory devices are not only convenient for storing backup files, but they also allow computer users to expand their ability to transfer large amounts of data to another Secondary memory devices. Therefore, every program you execute and every file you access must be copied from a … What is Auxiliary memory (secondary storage)? It means data is stored permanently even if power is switched off.
