Storage Device Defination: -

Storage Device are those Device which is used to store data. Whenever we need to store any data at that time we used storage Device.
A storage device is among the essential components of any computer system, and it comes in a variety of shapes and sizes depending on the requirements and functionality. It holds almost all of the large datasets in a computer, except the exception of hardware-software. A storage device comes in a variety of shapes and sizes; for example, a computer has numerous file systems such as a hard drive, RAM, and cache. These have also optical disc drives and USB drives that may be linked outside. There are two sorts of storage systems that store data: main and secondary.
There are Many Storage Devices are Available in the Market. Example :-
Types of computer storage
Primary storage devices: primary storage is also referred to as internal memory. This is a component that is present inside the CPU which is used to store the temporary files and process them to get immediate results. The best examples for primary storage devices are RAM (Random access memory) and ROM (Read-only memory).
Secondary storage devices: From the name itself this can be known that this is a type of secondary storage which is external to the computer system. It is not as primary storage as here the data is being stored for the long term or we can say it’s permanent storage.
Primary storage devices
RAM
RAM means random access memory which is used to access any temporary data and to get intermediate results for the usage of that information. It is also known as temporary memory because the data will be stored only till the computer system is on, if it’s turned off the data will be lost.
ROM
ROM means read-only memory. This is also known as non-volatile memory as the information here is stored permanently until and unless it’s deleted by the user.
Secondary Storage Devices
Floppy Disks.
Magnetic Tapes.
Hard Disks.
Optical Disks.
Flash Memory Devices
Floppy disk: - The floppy disks are one of the oldest types of portable storage devices still in use. The floppy disks enable one to transfer small files between computers and also to start data/information as a backup. A standard floppy disk can store up to 1.44 Mb of data which is approximately equivalent to 300 A4 pages of text. However, if you have included graphics or pictures in it, your work will not fit in the floppy disk as graphics/pictures take up more space than text.
Megnetic Tapes :- Magnetic tape is a secondary storage device that can hold large volumes of data on it. The tape is a sequential access media and data on it can be accessed sequentially. Large files are stored on them. It is one of the most popular storage media because of its lower cost. These are similar to the tapes used in music cassettes or videotapes, in which data can be erased and reused.
Hard Disk :- The hard disk memories store information on one or more circular platters (or disks) which are continually spinning. These rotating disks are coated with a magnetic material and stacked with space between them. Information is recorded on the surface of rotating disks by magnetic heads as tiny magnetic spots. These Heads are mounted on access arms. Information is recorded in bands. Each band of information on a given disk is called a track.
Optical Disks: - Optical disks offer a higher density and reliability than magnetic disks. These disks are produced using laser beams. They are made of plastic or metal with a highly reflective coating, usually aluminum. In an optical disc, two laser beams are used one for reading data and another for writing data. The most commonly used optical disks are CDs, DVDs, and Blu-ray.
Flash Drives :- Flash memory is an electronic (solid-state) non-volatile computer storage medium that can be electrically erased and reprogrammed. They are either EEPROM or EPROM. Examples of Flash memories are pen drives, memory cards, etc. Flash memory offers fast access times. The time taken to read or write a character in memory is called access time. The capacity of the flash memories varies from 1 Gigabyte (GB) to 2 Terabytes (TB).
Note :- Some Basic Storage Device examples are -
Solid-state drives (SSDs).
Hard disk drives (HDDs).
Cloud storage.
CD-ROM drives.
DVD drives.
Blu-ray drives.
USB flash drives.
SD cards.
Floppy diskette.
Tape drives.
Zip and Jaz drives.
(Frequently Asked Questions)
Q1. What are computer storage devices?
Answer. A storage device enables its user to store and securely access data and applications on a computer device.
Q2. What are secondary storage devices?
Answer: Secondary storage devices are non-volatile in nature, which means that data is not deleted when the storage is turned off, and it has a much higher storage capacity than primary storage devices.
Q3. What are examples of storage devices?
Answer: Some of the widely used storage devices are CDs, DVDs, Pen drives, Memory Cards, SSD, and HDDs.
Q4. What is a magnetic storage device?
Ans. Magnetic storage devices are non-volatile storage in nature, and data are stored using magnetic medium and such data is stored in binary form as 0 and 1.
Q5. What are examples of an Optic storage device?
Ans. Examples of common optical storage devices are CD-ROM, Blu-Disc, DVD, CD-R.
