Hello Dears! Today, here we will explain about what is secondary memory with its examples and uses; involve with different types of secondary memory in computer with ease. At the end of this post, you will definitely aware about Secondary Memory without any hassle.
What is Secondary Memory?
Definition:Secondary Memory has other names like “storage device” and “auxiliary memory“, “external memory“. Secondary memory devices are volatile in nature, it means that data does not discard while power turn-off, in which all data store for long time.
Secondary memory has the speed of access of data is very slow compared to primary memory, and cheaper as well. Without primary memory, those secondary memory devices are useless because for processing the secondary memory must be needing the primary memory, first of all data get transfer into primary memory then these data make for executable.

Types of Secondary Memory with Examples
Secondary memory can be used in computer either internally or externally. Secondary Storage memory is classified into four different categories like as:
In the Magnetic storage devices, all data store with using magnetized medium, and those types of data saved in that medium in the binary form like as 0 and 1. This magnetic storage has also non-volatile storage nature.
Today’s, mostly people are going to prefer magnetic medium because on the magnetic storage devices can perform read/write activities very easily.
Magnetic storage devices have huge capacities for storing data that it’s more attractive point. These storage devices are not more costly but their data accessing power is slow, but this magnetic mechanism is also using in the RAM that have good data accessing power to other.
Examples Are:
Floppy diskette
Hard drive
Magnetic strip
SuperDisk
Tape cassette
Zip diskette
Optical Storage Devices:
In the optical storage devices, all read and write activities get perform with optical light. All recording information stores at an optical disk. As per the opinions of data scientist that compact space is most useful for huge data storage. Their big advantages are not more costly, light weight, and easy to transport because it is removable device unlike hard drive.
Examples Are:
Blu-ray disc
CD-ROM disc
CD-R and CD-RW disc.
DVD-R, DVD+R, DVD-RW, and DVD+RW disc.
Flash Memory Devices:
Flash Memory introduced by Dr. Fujio Masuoka in 1980. This device has also another name electronically erasable programmable read only memory (EEPROM), because in which piece of code like as programming can write and erased by electrically.
This memory also uses for the storing data to computers as well as electronic devices such as USB flash drives, MP3 players, digital cameras and solid-state drives. Flash memory is non volatile in nature because all data persist in the memory when power is turn-off.
Examples Are:
USB flash drive, jump drive, or thumb drive.
CF (CompactFlash)
M.2
Memory card
MMC
NVMe
SDHC Card
SmartMedia Card
Sony Memory Stick
SD card
SSD
xD-Picture Card
Online Cloud System:
Clouding is systematically model for storing data in computer, and in which entire data get store in logically nature. Those clouding system are managing by other hosting companies. With the help of online clouding, all data can access by couples of users anytime and anywhere. Big advantages are not place limitation as well as no need carry any storage device.
There are some types:
Cloud storage
Network media
Examples of Secondary Memory in Computer
In this section, we will spread light on the various examples of secondary memory, which are going to use in your computer system; below shown each one, you can check them:
Floppy Diskette: Someone also say itI the ‘Floppy Disk’ that constructed of a plastic disk plate. It is small in size and its disk is a flexible outer layer made of iron-oxide. Floppy disk contains the plastic cover named jacket. At the centre of jacket, there is a point from where it moves 360 RPM per minute.
Hard Drive: It is an electro-mechanical data storage memory that allows keeping store and fetching digital data by using of magnetic storage along with single or multiple rigid rapidly rotating palters coated with magnetic material.
Solid State Drive: SSS (Solid State Drive) is going to use keep store and fetch all information from the computer; it works just as a hard disk drive. As well as, SSD has not any movable parts. Without having any moving parts, its data can easily access, saving time and energy.
Pen Drive: Pen drives have other names the USB flash drives, thumb drives, and jump drives. They are portable hard drives that connected by USB port to the computer system. This drive can use for transfer and data storage as well. They are plug & play device that means, they don’t need any special software for using.
Magnetic Strip Card: The magnetic strip card designed with magnetic technology that lets information to read, whenever the card swept through a card reader.
SuperDisk: The SuperDisk LS-120 is a higher speed, highly capacity that is best alternative to the 90 mm, 1.44 MB floppy disk. It introduced by Imation, 3M’s storage products group in the mid-1990s.
Blu-Ray Disc: Blue-ray disk is an optical storage medium that allows to keep store high definition videos and other stuffs. As compare with CD/DVD, blue ray disk uses less storage, and its storage capacity is 128 GB of data.
Memory Card: The memory card is an electronic data storage device that is going to use for keeping digital information, usually using the flash memory.it is mostly going to use in the digital portable electronic devices like as camera, mobile phone, PC, and etc.
DVD Drive: DVD stands for ‘Digital Video Disk’, and it is and optical media that allows to store optical data. It is look-wise as a CD but its storage capacity is more as compare to CD. It is going to use for store movies and other software programs.
CD Drive: CD-drive is also a portable secondary storage device that is round in shape and constructed with poly carbonated plastic. It is going to use for storing data such as audio files, Video, text, images, documents, numbers and software programs.
SD Card: SD card stands for the ‘Secured Digital Card’. It is a portable storage device that is mostly using into mobile phones and digital cameras. Users also can connect it along with computers and share data by using the card reader. SD card contains the many chips that help to store data and information as permanently.
SD card has few variants like as:
Standard SD cards
