Question

Answer 1

Answer:

primary data example

Explanation:

yes

Answer 2

Primary memory is the main memory where the data and information are stored temporarily.

Secondary memory refers to the external memory where data is stored permanently.

The Difference Between Primary And Secondary Memory Are:-

• In Primary Memory where the data is directly accessed by the processing unit whereas, in Secondary Memory, data cannot be accessed directly by the processor.

• Primary memory is an unstable memory meaning data cannot be retained in case of power failure whereas, Secondary memory is a stable memory so data can be retained even after power failure.

• In Primary Memory, the memory is stored in semiconductor chips which are relatively expensive whereas, in Secondary Memory, the memory is stored in external storage devices such as hard disks, flash drives, etc.

• Primary memory can be classified into cache memory and random access memory (RAM) whereas, Secondary memory is permanent storage devices such as CDs, DVDs, HDDs, floppy disks, etc.

• Primary memory is somewhat faster than secondary memory because of its volatile nature whereas, Secondary Memory is usually slower than primary memory. It's like a backup memory.
