20 Examples of Storage Devices

The storage devices Data are the components of a computer system that have the role of transmitting or retrieving digital information (Record Y read) on various physical media created for it. For example: RAM memory, Zip drive, Hard drive.

They should not be confused with the storage media of data or data storage medium, terms that refer precisely to the physical vehicle of the information, either those handled by a computer or by a device of another nature.

Examples of storage devices

1. RAM. Acronym for Random Access Memory (Random Access Memory), is the storage field used as a working medium in the systems computational, as it contains all the processor instructions and most of the instructions of software. Shutting down or restarting the system erases all of its content.
2. ROM memory. Acronym for Read-Only Memory (Read Only Memory), is a storage medium that contains data that is difficult (or impossible) to modify, vital for the basic functioning of the computer system and its operating system primary.

3. Magnetic tape cassettes (DAT). These are systems for recording and reading digital audio information, which handle small plastic devices or cassettes with magnetic tape inside, which operate similarly to their cousins analog.
4. Digital Magnetic Tape Devices (DDS). Derived from DAT systems, they are digital and computerized information management units from magnetic tape, remotely similar to the VHS format.
5. 3½ floppy drives (obsolete). Evolution of the floppy disk drive, these drives used more rigid and durable floppy disks, with higher capacity (1.44 MB).

1. Hard or Hard Disk Drives. Known as HDD (Acronym for Hard Disk Drive), are units with much larger storage than optical discs and memories, but they are usually found inside the CPU and are not removable. That is why they usually contain the information of the operating system and the content of files and computer software in their entirety.
2. Portable Hard Drives. Removable and external version of the hard disk, they connect to the computer through its I / O ports and hold large amounts of information.
3. CD-ROM drives. Acronyms for Compact Disc Read-Only Memory (Compact Disc Read Only Memory), are read only devices created in 1985 and that operate based on a laser beam which, reflected on the sheet within the disk, supplies the computer with a set of binary signals from the plains and crevices of this.
4. CD-R / RW drives. Similar to the CD-ROM, these drives allow not only the reading but also the partial or definitive writing of compact optical discs, in some cases allowing their reuse.
5. DVD-ROM drives. Acronyms for Digital Versatile Disc (Digital Versatile Disc), operates in a similar way to CD, that is, it is recorded only once and can be read in many opportunities, but with the difference that it sustains up to 7 times the information load of said formats.
6. DVD-R / RW drives. These are DVD disc burning and rewriting drives, allowing up to 4.7 Gigabytes of information to be written to them.
7. Blue Ray Units. This is the name of a new generation optical disc format, endowed with much greater capacity for storage and reading quality, since the laser used for this reading is blue instead of the traditional red. Supports up to 33.4 Gigabytes per recording layer.
8. Zip drives. Introduced to the market in the mid-1990s, ZIP drives operate from high-capacity magnetic disks, from peripheral units. They were replaced by flash memories.

1. Flash Memory Drives. Connected to the equipment via USB or Firewire, these readers allow the support of information in a portable format compatible with digital cameras and electronic agendas.
2. Memory Card Drives. Like flash memory (arguably a form of it), portable devices of memory or memory cards allow the physical handling of information on a large scale through USB ports. There is a huge variety of models, known as Pendrive since some have the practicality of a ballpoint pen.
3. Punch Card Unit (Obsolete). Is technology It consisted of information reading systems from cardboard cards that were made a hole in a certain instead, to allow optical reading of the binary code: hole represented one value (1), no hole represented another (0).
4. Punched tape drive (obsolete). Similar to punch cards in operation, they went a step further, turning cardboard cards into a long instructional tape, allowing for much more information to be handled.
5. Magnetic drums (obsolete). One of the first forms of memory for computers, invented in 1932, stored information in layers of iron oxide through metals rotating that, although they were not removable, allowed to retrieve the information at high speeds.
6. Cloud storage. The development of online storage systems and high data transmission speeds on the Internet have allowed use it as a read / write device, so many entrust their files to "the cloud" rather than physical media.
