They can be represented in an hierarchical form as:  Computer Memory 1. Primary / Main memory: Primary memory is the computer memory that is directly accessible by CPU. It is comprised of DRAM and provides the actual working space to the processor. It holds the data and instructions that the processor is currently working on. 2. Secondary Memory / Mass Storage: The contents of the secondary memory first get transferred to the primary memory and then are accessed by the processor, this is because the processor does not directly interact with the secondary memory. Now, Let’s see the difference between Primary memory and Secondary memory:
What is the main difference between primary and secondary storage give two examples of each?Memory system can be divided into 4 categories: CPU register. Cache memory. Primary / Main memory.
...
. What are three differences between primary and secondary storage?Primary memory is the main memory (Hard disk, RAM) where the operating system resides. Secondary memory can be external devices like CD, floppy magnetic discs etc. secondary storage cannot be directly accessed by the CPU and is also external memory storage.
What are the 4 types of primary storage?There are four types of primary storage:. read only memory (ROM). random access memory (RAM). flash memory.. cache memory.. What are the 4 types of secondary storage?solid state storage devices, such as USB memory sticks. optical storage devices, such as CD, DVD and Blu-ray discs. magnetic storage devices, such as hard disk drives.
