Information Technology Fundamentals – Using Storage Devices
What is a Storage Device?
A storage device is a type of hardware that may temporarily or permanently store information. It is also known as storage, storage medium, digital storage, or storage media. It is typically used to store, transfer, and extract data files. It can be used internally or externally to store data on a computer system, server, or other computing device.
A storage device is one of the essential components of any computer device, and it is available in a variety of shapes and sizes based on the device's requirements and capabilities. Except for hardware firmware, it stores the majority of the computer's data applications. A storage device is available in numerous physical configurations; for instance, a computer device may contain various storage media, such as a hard drive.
Why is storage in a computer necessary?
Without a storage device, a computer would be classified as a dumb terminal. It cannot store or retain any type of data or configurations if it lacks a storage device. Even while your computer can operate without storage media, you can only view or read the information on it if it is connected to a computer with storage capabilities. In addition, a storage device is required to store information on such activities as Internet browsing.
What is a storage location?
When storing any type of data on a computer or comparable device, you may be prompted to select a storage location. There are multiple types of data kept on your computer's hard disc by default. If you wish to transfer this data to another device, you must transfer it to a different storage medium, such as a USB flash drive. This allows you to transfer it to another computer.
Why are there so many unique storage devices?
Due to the rising demand for storage capacity, the technologies used to store data are advancing day by day with the expanding use of computers. There is a need for the development of new technologies as the demand for portable storage devices continues to rise. As new storage devices are developed, users replace older storage devices with newer ones. Therefore, previous gadgets are no longer required and are no longer in use.
Examples of computer storage
Magnetic storage devices
In modern times, hybrid hard drives or humongous HDDs are often used for magnetic storage.
The following is a list of magnetic storage devices:
- A hard disc drive (HDD) is a non-volatile computer storage device used to store data permanently. It is directly attached to the disc controller of the computer's motherboard. It is typically installed internally in a computer and is referred to as a secondary storage device.
- Floppy diskette: A floppy disc drive (FDD) offers users the benefit of saving data to detachable diskettes. FDDs have been replaced with network file transmission and USB storage devices.
- SuperDisk: The disc storage technology was developed by Imation Corporation. SuperDisk is alternatively referred to as an LS-240 and an LS-120. The drive was most prevalent in OEM computers and was capable of storing up to 120 MB (Megabyte) per disc. Later on, it could store 240 MB and was also compatible with 1.44 MB drives.
- Magnetic Card: A magnetic card may include information about an individual, such as passcodes to enter secure facilities or available recognition on credit cards.
- Zip diskette: A Zip drive is an upgraded version of the floppy disc hardware data storage device. It was created by Iomega and resembles a diskette and conventional 1.44" floppy drive. It became quite popular in the late 1990s and was capable of holding data that conventional floppy discs could not.
- Cassette tape: A tape is a rectangular and flat container that may store data. It is less expensive than other storage medium and is routinely used to back up vast amounts of data.
Optical storage devices
Another type of storage devices are listed in below:
- Blu-ray disc
- CD-ROM disc
- CD-R and CD-RW optical discs
- DVD-R, DVD+RW, DVD+R, and DVD-RW disc
Flash memory devices
Flash memory is both inexpensive and portable. The majority of magnetic and optical media have been replaced by flash memory devices because they are a more dependable and efficient alternative.
A memory card is frequently utilised in digital cameras, printers, MP3 players, PDAs, digital camcorders, gaming consoles, and handheld computers. For many years, the most popular memory card format was CompactFlash, but today the most popular formats are CFexpress, SD, MicroSD, and XQD.
Flash drive: A USB flash drive is a portable data storage device that is sometimes referred to as a pen drive, thumb drive, data stick, and keychain drive. They connect to a computer through a USB port and are typically the size of a human thumb.
SDHC card (Secure Digital High Capacity): It is an enhanced version of the standard SD card that employs new technology. It is not compatible with SD format devices and has the capacity to store between 4 GB and 32 GB of data.
Compact Flash (CF) is a form of flash memory found in digital cameras, PDAs, and other portable devices. It is a 50-pin connection storage device capable of holding between 2 MB and 128 GB of data.
MultiMediaCard: A MultiMediaCard or MMC is an Integrated Circuit used in automobile radios, printers, personal digital assistants, MP3 players, and digital cameras. It serves as external data storage. The MMCP (MMCplus) and MMCM (MMCmobile / MMCmicro) are MMC card versions.
SSD: A solid-state drive is a storage medium similar to a hard disc drive (HDD). Even without power, it is able to keep the permanent condition of stored data. Because it has no moving parts, unlike a hard disc, it is more reliable, operates silently, consumes less energy, and provides faster access.
xD-Picture Card (EXtreme Digital Picture Card): In 2002, Olympus and Fuji introduced the xD-Picture Card, a flash memory card. Prior to the introduction of the Mini SD card in 2003, xD cards were the smallest flash memory cards available on the market. The H and M/M+ variants of the xD-Picture Card had a maximum capacity of 2 GB, while the original version had a maximum capacity of 512 MB.
SD Card: An SD Card, which stands for Secure Digital Card, is most frequently used with electronic devices that are intended to provide high-capacity memory in a tiny package. It is frequently utilized in small portable devices such as cell phones, digital cameras, digital video camcorders, and mp3 players, among others. More than 400 brands of electronic equipment use it.
Cloud-based and online storage
The demand for internet and cloud-based data storage is growing significantly.
- Cloud storage: Cloud storage is a cloud computing model that sends and stores data on remote storage systems that are managed, maintained, and made available to users across a network by a cloud computing provider. It provides customers with dependability, privacy, longevity, and "anytime data access."
- Network media: Network media is any audio, video, images, or text utilized on a computer network such as the Internet.
Initially, computers could not store data on any storage technology, such as flash memory devices or optical storage devices. Instead, they relied on paper. Paper storage is a way of storing data that is rarely utilized or encountered in modern times.
OMR: optical mark recognition or optical mark reading It is a technique for extracting information from humans by recognizing certain markers on a document, such as checkboxes and text fields on printed forms. With the use of a sheet of paper, the OMR procedure is often conducted by scanning that detects a reflection or transmission. This technique is advantageous for applications such as ballots, response cards, surveys, and questionnaires, which require the processing of a large number of hand-filled forms rapidly and accurately.
Punch card: Also known as Hollerith cards or IBM cards, punch cards are able to store information in the form of little punched holes. It is a simple sheet of paper used to input data into early computers.
