The storage device is classified in hard drive, CD/DVD recorder, drive, flexible memory, floppy drive and tape drive.
As always, we like to always clarify the terms in compounds, the word device refers to all those machines or systems that have the possibility to perform certain actions and by means of these to achieve a specific objective in mind.
While the word storage, it makes reference to the word store, which implies the action of able to protect or to contain certain information or a certain amount of things.
In such a way that is understood by a storage device, one that is capable of storing in its interior a certain amount of content depending on the capacity of the same.
The creation of these was due to the fact, that the area of technology and in particular of computing, computers did not have enough capacity to store all the information that could a person need, having to resort to devices alternate.
What are the types of storage device?
Hard disk drive
Known as the main device, which is present in all and each one of the computers, this can be considered the central unit of storage, which processes and stores all data that is entered in the computer.
With the passage of time and the management of hard information, there are several computers that do not meet the expectations of their customers, which is why these are seen in the need to seek external hard drive, which serves to protect the data further and so remain these in greater security, to be subjected to a copy double of his writing.
This is the disk drive oldest of all, which is represented by the floppy disk device in a peculiar square shape that had a magnetic stripe through which the information is stored, and allows a subsequent reading of the same.
Similar to the previous device, but that presents a higher technology in regards to the magnetic tape used, starting because these can achieve or can connect to the computer via the USB cable.
In effect, the centre of main storage, is a magnetic tape that has been in the interior of the device, it is here where many people believe that this category should include the devices of the floppy drive, since floppy disks are working under the same operation.
In general, it is considered that the storage devices of this type, they function as if a tape recorder is concerned, proceeding to the writing of the data in series on the tape, how alike these are read.
However with the passage of time, there were different models or ways of recording, which are:
Linear, in this case, the tape is written in both directions, so that it contains information both on the back, as in the previous part.
Helical scan, in this case, the recording is performed in directions obliquely on the tape.
Depressive illness, in this case the recording can be linear, but what varies is the speed the same, since that is starting to become the writing of data to a fast pace, until they, begin to fill the tape, at which time, the writing process becomes slower.
Multi-track, for this to be possible it is necessary that the tape is present a anchor more prominent than the other, because writing about the same will be done in parallel lines.
It follows a similar process to the previous device, but in this case the write is not performed on the tape, but rather, on the CD or DVD, to the process of these recordings is usually used an optical reader or a lens, which is responsible for the etching process and the subsequent reading of the data inserted.
Unit flexible memory
The most modern that exist today and that require a single USB connection to make the recorded content or to make the transfer of information, to be referred to these as a stick, which, despite their size, have a high level of storage.
