Sagot :

Answer:

1. Hard Disk Drives

- A hard disk drive (also known as a hard drive, HD, or HDD) can be found installed in almost every desktop and laptop computer. It stores files for the operating system and software programs as well as user documents, such as photographs, text files, videos, and audio. The hard drive uses magnetic storage to record and retrieve digital information to and from one or more fast-spinning disks.

2. Floppy Disks

- Also know as a diskette, floppy, or FD, the floppy disk is another type of storage medium that uses magnetic storage technology to store information. Floppy disks were once a common storage device for computers and were very common from the mid-1970s through to the start of the 21st century. The earliest floppies were 8 inches (203 mm) in size, but these were replaced first by 5.25-inch (133 mm) disk drives and finally by 3.5-inch (90 mm) versions.

3. Tapes

- In the past, magnetic tape was often used for digital data storage because of its low cost and ability to store large amounts of data. The technology essentially consisted of a thin, magnetically coated piece of plastic wrapped around wheels. Its relative slowness and unreliability compared to other data storage solutions have resulted in it now being largely abandoned as a storage medium.

Answer:

The three basic types of data storage devices are primary storage, secondary storage, and tertiary storage.

Primary storage (also known as main memory ) is the component of the computer that holds data , programs and instructions that are currently in use. Primary storage is located on the motherboard . As a result, data can be read from and written to primary storage extremely quickly. ... random access memory (RAM)

Secondary storage is non-volatile , long-term storage. ... There are three main types of secondary storage in a computer system: solid state storage devices, such as USB memory sticks. optical storage devices, such as CD, DVD and Blu-ray discs. magnetic storage devices, such as hard disk drives

Tertiary storage comprises high-capacity data archives designed to incorporate vast numbers of removable media, such as tapes or optical discs. The removable media are normally not stored in suitable drives but held in specially arranged retention slots, shelves, or carousels in an offline state.
