For long-term storage of information is what device? Forms of storing information

Any of the users at least once thought about how they store your personal data and information. Of course, things like wedding photos or videos, I want to keep a long memory. However, how to do it?

Concept

Informatics specifies that for long-term storage of information is the external storage device, i.e. all the possible drives and media that you can imagine. As you know, to ensure the security and integrity of data can be different. Let's define, what are the different forms of information storage.

• Graphics/fine. the Most ancient method, fit for storage of information. He appeared in prehistoric times in the form of rock paintings, passed the stage of painting and turned to photography. In addition, information in graphical form is presented in the form of drawings and diagrams.
• Text. the Most common today is a way of storing data. A variety of books and records, libraries. If to speak about reliability, then this storage method is not only protected from theft, but also short-lived. The best preserved is that of a cookbook, originally printed on materials adapted to corrosive environment.
• Next step after the invention of writing, mathematics,, the numeric form of information storage. a Fairly specialized field, is used to determine the quantitative characteristics of an object, the surrounding space.
• The Recorder. The ability to store sounds appeared only in 1877 with the invention of recording devices.
• Video. The next step in the storage of graphical information created by the creation of cinema.

Processes Information

Under the information processes involve the retrieval, storage, transmission, use and processing of information. The main and primary thing is to preserve data. What's the difference whether we will be able to receive or transmit information, if we are not able to save it?

The Main information process is the process of storing information. This method of data transmission in space and time. For long-term storage of information is the device or fixture, depending on the type of data stored. To ensure the orderliness of this process are information systems. Any such system include search procedures, placement and I/o data. The main feature of the information system is the availability of all these key procedures. For example, compare the two libraries. A private library at home in the closet is not an information system because it is targeting only you. On the other hand, public city library, where everything is ordered according to the card index and there are standardised procedures for issuing / receiving books, is undoubtedly the system.

Computer age

With the development of even computer and Internet information system moderniziriruyutsya. The storage process is simplified due to the possibility of its translation into digital form. And despite the belief of some people that e-books or patterns do not carry a soul, for long-term storage of information is this method of saving data is much more effective than the others, and includes all possible information, unless you can translate it in digital form.

Modernity

For long-term storage of information is a personal computer and its external devices. They are divided into several types depending on the recording method.

• Optical disks
• Hard drive
• Flash memory.

Optical drives have different volume and better adapted for transmission and storage of information. Hard drives are designed to store large amounts of data, but their reliability leaves much to be desired. And, of course, flash. They are the Central link between the hard and optical disks provide a storage of information in sufficient quantities and for long enough period of time, not soak them. In any case, the method of storage you choose.
