The function of secondary storage is the long-term retention of data in a computer system. Unlike primary storage, or what we refer to as memory, secondary storage is non-volatile and not cleared when the computer is powered off and back on.

What is the function of secondary storage?
Secondary storage is non-volatile , long-term storage. It is used to keep programs and data indefinitely. Without secondary storage all programs and data would be lost the moment the computer is switched off.
What is the main function of storage in computer?
Storage houses your applications, operating system and files for an indefinite period. Computers need to write information and read it from the storage system, so the speed of the storage determines how fast your system can boot up, load and access what you've saved.
What are the main function of main memory and secondary memory?
Computer memory is categorized into primary and secondary memory. While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.
What is the main secondary storage of a computer?
There are three main types of secondary storage in a computer system: 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.
What is secondary storage device?
A secondary storage device refers to any non-volatile storage device that is internal or external to the computer. ... A secondary storage device is also known as an auxiliary storage device, backup storage device, tier 2 storage, or external storage.
What is the function of storage?
Storage is defined as 'the marketing function that involves holding goods between the time of their production and their final sale. ' It bridges the gap between the time when goods are produced and the time when these are ultimately consumed as there is always a time gap between production and consumption.
What is primary storage and secondary storage?
Primary storage refers to the main storage of the computer or main memory which is the random access memory or RAM. ... Secondary storage, on the other hand, refers to the external storage devices used to store data on a long-term basis.
What is the most widely used secondary storage medium?
The most common type of secondary storage medium is the magnetic disk. Diskettes (small disks made of flexible plastic) and hard disks (made of rigid metal) are the two different kinds of magnetic disks.
What is different between main memory and secondary memory?
Primary memory is directly accessible by Processor/CPU. Secondary memory is not directly accessible by the CPU. ... The memory devices used for primary memory are semiconductor memories. The secondary memory devices are magnetic and optical memories.
What is secondary memory example?
Secondary memory is known as a Backup memory or Additional memory or Auxiliary memory. Hard Drive, SSD, Flash, Optical Drive,USD Drive are some examples of secondary memories in computer.
Why computers have both main memory and secondary storage?
Because the main memory can quickly let the program access data from any random location, but can easily be erased when the computer is turned off. Secondary storage can help keep some of the lost data and can create a backup for important files or programs regardless of the computer power.
How does secondary memory work?
Unlike primary memory, secondary memory is not accessed directly by the CPU. Instead, data accessed from secondary memory is first loaded into RAM and is then sent to the processor. ... Therefore, secondary memory is used to store "permanent data," such as the operating system, applications, and user files.
What is secondary memory describe the two main types of secondary memory?
There are two main types of secondary memory Magnetic and optical media. The magnetic media is coated with a magnetic Layer. Various types of magnetic media : (i) Floppy disks – A floppy disk is a flexible disk with a magnetic coating.
What are the advantage of secondary memory?
Free up capacity on primary storage
Storing infrequently accessed data on secondary storage devices frees up space in primary storage and increases performance. Secondary storage can be used for: File and database backups for disaster recovery and business continuity.
