Question

5 differences between primary and secondary memory

Answer 1

Answer:

1. Primary / Main memory: Primary memory is the computer memory this is immediately available with the aid of using the CPU. It is created from DRAM and offers the real running area to the processor. It holds the records and commands that the processor is presently running on.
2. Secondary Memory / Mass Storage: The contents of the secondary memory first get transferred to the number one memory after which are accessed with the aid of using the processor, that is due to the fact the processor does now no longer immediately have interaction with the secondary memory.

Differences between primary and secondary memory

• Primary memory is temporary.
• Primary memory is immediately available with the aid of using a Processor/CPU.
• The nature of Parts of Primary memory varies, RAM- is unstable in nature. ROM- Non-unstable.
• Primary memory devices are greater pricey than secondary storage devices.
• Primary memory is likewise called Main memory or Internal memory.
• Examples: RAM, ROM, Cache memory, PROM, EPROM, Registers, etc.

Secondary memory

• Secondary memory is permanent.
• Secondary memory isn't immediately available with the aid of using the CPU.
• It’s continually Non-unstable in nature.
• Secondary memory devices are much less pricey whilst in comparison to number one memory devices.
• Secondary memory is likewise called External memory or Auxiliary memory.
• Examples: Hard Disk, Floppy Disk, Magnetic Tapes, etc.

Answer 2

Answer:

Differences between primary and secondary memory.

Explanation:

• Primary memory also known as primary storage is the component of the computer that holds data, programs and instructions that are currently in use.
• Secondary memory is a computer that is non- volatile, persistent and not immediately accessible by a computer or processor.
• Primary memory is a volatile memory whereas the secondary memory is non- volatile memory.
• Primary memories are semiconductor but secondary memories are the magnetic and optical memories.
• Data accessing is faster in the primary memory while data accessing in secondary memory is little slow.
• An example of primary memory is RAM and ROM that store programs.
• Hard drives, CD-ROM and DVD-ROM drives, floppy disk drives and tape drives are example of secondary memory.

Hence this is the difference between primary and secondary memory.
