Any of the users at least once thought about how to store their personal data and information. Of course, I want to keep things like wedding photos or videos for a long memory. However, how to do this?
The concept
Computer science determines that for the long-term storage of information an external storage device is used, that is, all possible drives and media that can be imagined. As you understand, there are many ways to ensure the safety and security of data. Let's determine what forms of information storage exist.
- Graphic / Fine. The oldest method, adapted to store information. He appeared in prehistoric times in the form of cave paintings, went through the stage of painting and turned into the art of photography. In addition, information in graphical form appears in the form of drawings and diagrams.
- Text. The most common way to store data today. 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. Only cookbooks, which are originally printed on materials adapted to hostile environments, are best preserved.
- The next step after the invention of writing is mathematics , a numerical form of storing information. A fairly narrowly specialized area is used to determine the quantitative characteristics of any object surrounding the space.
- Sound recording . The ability to store sounds appeared only in 1877 with the invention of sound recording devices.
- Video information . The next step in storing graphic information that appeared with the creation of cinema.
Information processes
Information processes mean the search, storage, transmission, use and processing of information. The primary and foremost concern is data storage. What difference does it make if we can receive or transmit information if we cannot save it?
The main information process is the process of storing information. This is a way of transmitting data in space and time. For long-term storage of information, a device or device is used, depending on the type of data stored. To ensure the orderliness of this process are information systems. Any such system is equipped with procedures for searching, placing and input / output of data. The main distinguishing feature of the information system is the presence of all these key procedures. For example, compare two libraries. The private library in your closet is not an information system, since only you are oriented in it. On the other hand, the public city library, in which everything is organized according to the file cabinet and there are standardized procedures for issuing and receiving books, is undoubtedly a system.
Computer age
With the development of not even a computer, but the Internet, information systems are being modernized. The storage process has been simplified due to the possibility of its digitalization. And despite the beliefs of some people that e-books or pictures do not carry a soul, for long-term storage of information, this method of saving data is much more effective than the others, and it includes all the possible information if you can translate it into digital view.
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 disks;
- flash memory.
Optical disks have a variety of sizes and are best suited for the transfer and storage of information. Hard drives are designed to store large amounts of data, but their reliability is poor. And, of course, flash drives. They are the middle link between hard and optical disks, provide storage of information in sufficient volumes and for a sufficiently long period, just do not wet them. In any case, you choose the storage method.
