Computer data storage is a technique mainly comprised of computer hardware and non-volatile recording media utilized to hold data. Computer data storage is therefore essential for all computing devices. It’s a central component and heart of computers, where all activities and processes are stored in their organized form. A computer storage medium holds all the information and system configuration and information, including user profile, operating system, desktop wallpaper, saved programs, control keys, preferences, etc. The medium can be used in several ways to make devices or servers work more efficiently and effectively. The data can be retrieved from the medium at any time, as required.

Computer data storage devices include CD ROMs, DVD ROMs, Floppy disks, Zip disks, and Internet data storage. All these storage devices are available in various capacities. They also differ in their methods of access and data retrieval. Based on the need and purpose of usage, the capacity of the storage device can be chosen.

Computer data storage devices store data in electronic memory cards or solid-state drives. Electronic memory cards can hold vast amounts of data but are comparatively slow in accessing that data. On the other hand, solid-state drives have better storage capacities and speeds and thus are used widely for high-end computers. Floppy disks use read/write heads, and magnetic disks use magnetic stripes for storing data. Both solid-state drives can be installed into a single PC or installed within a single mainframe computer. It can be configured after installation, depending on the requirements of the system.

CDs and DVDs This type of storage media can be used in a variety of ways. It can be burned into the CD or DVDs or can be written to the same. They can also be read from the DVD or CD or stored on the same. The data can be retrieved through the read-once and write-once methods. Storage A CD storage device is usually fixed or built into the computer system, while a DVD storage device is placed on a disk drive.

LCDs and Plasma screens A great variety of storage media such as floppy disks, CD-ROMs, DVDs, DVDs, USB flash drives, LCD screens, and plasma screens are employed in our daily lives.

Some of the leading brands of these storage devices include Samsung, Toshiba, HP, and Compaq. LCDs or flat-screen monitors employ liquid crystal displays, which can be seen in flat, rectangular, square, or rectangular shapes.

Hard disks, DVDs, CDs, and cable televisions act as storage mediums over more extended periods. The primary benefit is that they do not require any particular operating systems, and they perform well even under adverse conditions. The other advantage is that they do not need to be loaded with software and other programs before using them. The other storage mediums use software to load programs into their storage media. Another advantage of them is that they are relatively cheap and can store large volumes of data. However, the disadvantages of this storage media are that they consume more power and are slower than solid-state storage.

File cabinets, storage cabinets, and other storage furniture refer to the fixed furniture used to store different types of files. They are made of wood, metal, and other materials. The main benefit of them is that they store files and documents safely. A file cabinet helps in maintaining the orderliness of a working office by providing short-term data access.

External hard drives refer to compact discs attached to the computer or a laptop for storage. The significant advantage is that they can store data efficiently. On the contrary, they have disadvantages such as being slow and requiring more space for storing. Computer storage devices are also known as computer storage devices.
