What are the 10 types of storage device?

Ther Are have 10 types of storage device-

1.Hard Drive Disks
2.Floppy Disks
3.Tapes
4.Compact Discs (CDs)
5.DVD and Blu-ray Discs
6.USB Flash Drives
7.Secure Digital Cards (SD Card)s
8.Solid-State Drives (SSDs)
9.Cloud Storage
10.Punch Cards

1.Hard Drive Disks
Hard Drive Disk (HDD) is the most commonly used storage devices. These drives are used for storing, back ups and other purposes. Modern hard drives use two types of media-interchangeable disk drives (HDD), known as spinning-platter hard disk drives (HDDs), and solid-state drives (SSDs).

2.Floppy Disks
This type of disk is now obsolete and known as a “Floppy Disk”. The floppy disks drives were first made by IBM and later by the Sony Corporation and Matsushita Electric and Panasonic Corporation. These drives were used in personal computers since the 1970s, but were soon replaced with hard drives, because floppy disk drives became larger and more complex as they evolved. When hard drive storage was introduced, there was no need to continue using floppies. Today, floppy disks are only useful for archiving old computer programs or data that is still “in use”. Currently one can purchase a discount card for organizing old things at www.oldspointers.com.

3.Tapes
Tapes are used to store audio and video content on. A VHS-C (very high-quality) video cassette is the most widely used type of cassette Tape, but there are various other tapes available on the market, such as audio cassettes, computer tapes, etc. The advantages of tape over CD or DVD are that they are faster, can be erased and rewritten many times, can record/play at higher fidelity levels for audio/video recording/reproduction, have a longer length of data retention time than both CD-ROMs and DVDs, can be reused more easily than hard drives or memory chips that might become damaged over an extended period of time.

4.Compact Discs (CDs)
This is a kind of optical disc storage device that can store data, music, video and programs. The highest capacity of a CD is 700 MB. CD-ROMs are used to distribute software or data in bulk to users. One good example is when computer programs are distributed through the internet. The reason for this is because CDs are cheap to make and deliver much more information than floppy disks do in much less time, thus saving the internet provider time and money when sending gigabytes of information to users all over the world. CDs store their information on a layer of the disc called the “coating”. Data is encoded in pulses that are then modulated into laser light. Data is read by an optical pick-up (similar to the ones used in DVD players) which converts this information into electrical impulses.

5.DVD and Blu-ray Discs
DVDs and Blu-ray Discs are optical disc storage media, with duplication functions similar to CD/DVD-ROMs or hard disks. This allows for larger amounts of data to be stored, while also offering the same use as CD-ROMs, including video games, software and movies. The difference is that they hold more data than CDs and therefore can hold movies with a high visual quality.

6.USB Flash Drives
These storage devices are commonly used in digital cameras, mp3 players and many other small electronic devices where large amounts of data must be stored. A USB flash drive is a small pocket sized device that can easily be carried around in a pocket or in a bag and is ideal for transporting documents and other valuable information from one computer to another. Due to the nature of the technology used in USB flashing drives, data can be saved or deleted via software that is installed on the computer. This allows the user to update the drive with new information easily and easier than using a normal floppy, and generally gives you more space to save data.

7.Secure Digital Cards (SD Card)s
This kind of device is also called a Secure Digital Memory Card (SD card). It is widely used in various devices such as cameras, camcorders, mobile phones, PDAs and many other digital electronics. The Secure Digital Card (SD card) is not the same as USB Flash Drives, despite its similarity in shape and size. This type of storage device was invented by SanDisk Corporation.

8.Solid-State Drives (SSDs)
Solid-state drive (SSD) is used to store data on electronics that are equipped with Flash memory. SSDs are similar to USB flash drives but they use Solid State instead of Flash memory. With SSDs, data is stored in the NAND memory semiconductor chips, hence the name “Solid State”. This kind of storage device can be very fast, as compared to traditional hard disk drives, and provides more storage space than any other type of computer storage medium.

9.Cloud Storage
The cloud is a collection of networks, networks that are interconnected using technology such as server farms and high-speed internet connections. It is a convenient way to store data on the internet. Organizations like Google, Amazon, and Microsoft provide cloud storage for end-users.

10.Punch Cards
The punch card was used by operators of the United States Census Bureau before the 1970s to keep records on individual people or households. A punched card consisted of holes that had to be punched with a hole punch to record certain facts about individuals (such as name, age, sex, race). A piece of paper with rows and columns of these holes was attached to an individual’s record. This paper could be inserted into an input slot in a computer terminal where it would be read by software that would do automated data processing for further analysis purposes. A punched card program could then be used to generate reports or batches of punched cards for mailing out to individuals in a population.

Although most punching and reading is done manually in the field by census takers, in these times of high digitalization and e-government, all forms of data input and output can be automated with the application of new technologies.
