Storage devices can store information both temporarily and permanently and include primary and secondary storage. Primary storage includes RAM and ROM which store data temporarily while the computer is running. Secondary storage devices like hard disks and magnetic disks store data permanently. The key differences between primary and secondary storage are that primary storage is directly accessible by the CPU, volatile, and more expensive while secondary storage is non-volatile, not directly accessible by the CPU, and less expensive. Storage devices are important as they allow users to store and backup important data.

3. • Storage device is a kind of hardware that has the ability to store information either
temporarily or permanently. It is also known as storage medium, digital storage, or
storage media.
• You will be introduced to the functionsof motherboard, RAM, ROM, and CPU, etc.

4. WHAT IS THEIR IMPORTANCE
• It stores your information or personal data and keeps it secure.
• You can backup or archieve your important data that is deleted.
• In the business world, there is need to store data permanently and should not get
destroyed at that time Storage Devices are needed.

6. PRIMARY STORAGE DEVICES
A primary storage device is any storage device or component that can store nonvolatile
data in computers, servers and other computing devices. It is used to hold/store data and
applications temporarily or for a shorter period of time while the computer is running.

7. EXAMPLES OF PRIMARY STORAGE DEVICES
RAM : - It stands for Random Access Memory. It is used to store information
that is used immediately or we can say that is a temporary memory.
ROM : - It stands for Read Only Memory. This information is stored permanently
during manufactured only once.

8. SECONDARY STORAGE DEVICES
• A primary storage device is any storage device or component that can
store nonvolatile data in computers, servers and other computing
devices. It is used to hold/store data and applications temporarily or for
a shorter period of time while the computer is running.

9. EXAMPLES OF SECONDARY STORAGES
Hard Disk :- It is used to store Operating Systems, Software Programmes, and their files
using magnetic disks.
Magnetic Disk :- The device that uses a magnetization process to write, rewrite and
access data.

10. Primary memory Secondary memory
Primary memory is temporary. Secondary memory is permanent.
Primary memory is directly accessible by Processor/CPU. Secondary memory is not directly accessible by the CPU.
Nature of Parts of Primary memory varies, RAM- volatile in nature. ROM-
Non-volatile.
It’s always Non-volatile in nature.
Primary memory devices are more expensive than secondary storage
devices.
Secondary memory devices are less expensive when compared to primary
memory devices.
The memory devices used for primary memory are semiconductor
memories.
The secondary memory devices are magnetic and optical memories.
Primary memory is also known as Main memory or Internal memory. Secondary memory is also known as External memory or Auxiliary memory.
Examples: RAM, ROM, Cache memory, PROM, EPROM, Registers, etc. Examples: Hard Disk, Floppy Disk, Magnetic Tapes, etc.
Difference between Primary and Secondary storage

11. WHAT I LEARNED FROM THIS
MICROPROJECT
• From this Microproject, I learnt about different types of storage devices.
• Storage devices can hold , store files and objects and information both temporarily
and permanently.
• The storage devices is a important part of computer system that enables to store
data safely and access it whenever necessary.
