For long-term storage of information, which device? Forms of information storage

Anyone at least once thought about how to store his personal information and information. It's clear, such things as wedding photos or video, you want to keep on a long memory. However, how to do this?

The concept of

Computer science determines that for long-term storage of information serves as an external storage device, that is, all possible drives and media that can only be imagined. As you understand, it is possible to provide security and safety of data in different ways. Let's determine what forms of information storage exist.

• Graphic / graphic. The most ancient way, adapted to store information. It appeared in prehistoric times in the form of rock carvings, passed the stage of painting and turned into the art of photography. In addition, information in a graphical form appears in the form of drawings and diagrams.
• Text. The most common way to date is data storage. A variety of books and records, libraries. If we talk about reliability, then this method of storage is not only not protected from theft, but also short-lived. Best of all, except cookbooks, which are initially printed on materials adapted to an aggressive environment.
• The next step after the invention of writing is mathematics , the numerical form of information storage. A rather narrowly specialized area is used to determine the quantitative characteristics of an object, the surrounding space.
• Sound recording . The possibility of storing sounds appeared only in 1877 with the invention of sound recording devices.
• Video information . The next step in the storage of graphic information, appeared with the creation of cinematography.

Information Processes

Information processes include the search, storage, transmission, use and processing of information. The main and primary concern is the preservation of data. What difference does it make whether we can receive or transmit information if we can not keep it?

The main information process is the process of storing information. This is a way of transferring data in space and time. For the long-term storage of information is a device or device, depending on the type of stored data. To ensure the orderliness of this process, information systems serve. Any such system is equipped with procedures for searching, allocating and inputting / outputting data. The main distinguishing feature of the information system is the availability of all these key procedures. For example, let's compare two libraries. The private library in your home in the closet is not an information system, because only you are guided in it. On the other hand, a public city library, in which everything is organized according to the card index, and there are standardized procedures for issuing and receiving books, is undoubtedly a system.

The Computer Age

With the development of not even a computer, but the Internet, information systems are being modernized. The storage process was simplified due to the possibility of its digitization. And despite the beliefs of some people that electronic books or pictures do not carry souls, for long-term storage of information this way of data preservation is much more effective than others, and includes all the possible information, if only you can translate it into digital view.

Modernity

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

• Optical disks;
• hard disks;
• Flash memory.

Optical disks have very different volumes and are best suited 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 drives. They are the middle link between hard and optical disks, ensure the storage of information in sufficient volumes and for a fairly long time, just do not wet them. In any case, the method of storage is your choice.
