There are so many concepts in Russian that it is sometimes difficult to distinguish between two very similar, but still different definitions. But there are such terms that do not carry additional meanings, but have a clear and understandable interpretation. For example, the concept of "electronic storage medium." This is the definition of a material medium that records, stores and reproduces data that is processed by computer technology.
How did it all start?
A more general meaning of this term is “information medium” or “information medium”. It defines a material object or environment that is used by man. Moreover, such an item stores data for a long time, without using additional equipment.
If an energy source is needed to store information on electronic media, a simple data medium can turn out to be stone, wood, paper, metal and other materials.
A storage medium may be any object that shows the data printed on it. It is believed that information media are needed for recording, storage, reading, transfer of materials.
Features
It is easy to guess that an electronic storage medium is a type of information storage medium. It also has its own classification, which, although not officially established, is used by many experts.
For example, electronic media may be write-once or multiple-write. Devices are meant here:
- optical;
- semiconductor;
- magnetic.
Each of these mechanisms has several types of equipment.
An electronic storage medium is, first of all, a number of advantages over paper options. First, thanks to technology, the amount of archived data can be almost unlimited. Secondly, the collection and submission of relevant information is ergonomic and fast. Thirdly, digital data is presented in a convenient form.
But electronic media has its drawbacks. For example, this can include the unreliability of equipment, in some cases, the dimensions of the device, dependence on electricity, as well as the requirements for the constant availability of an apparatus that could read files from such a digital drive.
Variety: Optical Discs
An electronic storage medium is a device that can be optical, semiconductor, magnetic. This is the only classification of such equipment.
In turn, optical devices are also divided into types. This includes a laser disc, CD, mini disc, Blu-ray, HD-DVD and so on. The optical disk is named so thanks to the technology of reading information. Reading from the disc occurs using optical radiation.
The idea of this electronic medium was born long ago. Scientists who developed the technology were awarded the Nobel Prize. A way to reproduce information from an optical disk appeared in 1958.
Now optical electronic media has 4 generations. In the first generation were: a laser disc, a compact disc and a mini-disc. In the second generation, DVDs and CD-ROMs became popular. In the third generation stood out Blu-ray and HD-DVD. The fourth generation is actively developing Holographic Versatile Disc and SuperRens Disc.
Semiconductor media
The next type of electronic information carrier is semiconductor. These include flash drives and SSDs.
Flash memory is the most popular electronic medium that has semiconductor technology and programmable memory.It is in demand due to its small size, low price, mechanical strength, acceptable volume, speed and low energy consumption.
The disadvantages of this option are the limited period of use and the dependence on the electrostatic discharge. For the first time, people started talking about a flash drive in 1984.
An SSD is a semiconductor electronic medium, also called a solid state drive. He replaced the hard drive, although at the moment he did not completely replace it, but only became an addition to home systems. Unlike a hard drive, a solid state drive is based on memory chips.
The main advantages of such a carrier are its compact size, high speed, wear resistance. But at the same time it has a great value.
Magnetic disks
And the last type of electronic media are magnetic devices. These include magnetic tapes, floppy disks and hard drives. Since the first and second equipment is not used now, we will talk about railway.
A hard disk is a device that has random access and is based on magnetic recording technology. At the moment, this is the main drive of most modern computer systems.
Its main difference from the previous form, the floppy disk, is that it is recorded on aluminum or glass plates, which are coated with a layer of ferromagnetic material.
Other options
Despite the fact that, speaking of electronic media, we often recall devices connected to a computer, this does not mean that this concept is used only in computer technology.
Distribution of electronic media is associated with its ease of use, high speed of writing and reading. Therefore, this equipment displaces paper media.
Documents
What is a passport with an electronic storage medium? At first, this question can drive a person into a dead end. But if you think carefully about it, then you recall the concept of “biometric passport”.
This is a state document that certifies the identity and citizenship of a traveler when he moves abroad and is in another country. In fact, we have the same passport, but with some nuances.
The difference between a biometric document and a traditional passport is that the first is a carrier of a specially mounted microcircuit that stores the owner’s photo card and his personal data.
Thanks to a small microcircuit, you can get the surname, name and patronymic of the owner of the document, his date of birth, passport number, time of issue and end of validity period. According to the sample, the microcircuit should contain the biometric data of a person. This includes a picture of the iris or fingerprint.
Document Introduction: Advantages and Disadvantages
A passport containing an electronic storage medium was introduced in 2002. Its distribution was affected by the September 11, 2001 terrorist attack in the United States. Then, many states of the world signed the New Orleans Agreement, which proposed the use of face biometry as a basic identification technology.
Despite the fact that a biometric passport has long been introduced by many states, some citizens have a negative attitude towards it. But this document has both advantages and disadvantages.
The advantages include the fact that the passage of the border point now does not take much time. If in such places there is special equipment that can read the microchip, then crossing the border becomes safe and fast.
But not all citizens like a biometric passport. Many believe that the introduction of such a document is a manifestation of the total control behind the US government.
Criminal case
The development of electronic storage media has affected many areas. The same can be attributed to a criminal case.In 2012, the term “electronic data carrier” was introduced into the Code of Criminal Procedure of the Russian Federation. Thus, such devices could become material evidence.
Electronic storage media have become an important detail in the investigation of a criminal case, subject to certain conditions. For example, data from the medium should be directly related to the investigation. In addition, their transfer must be carried out by a reliable source that could be verified. The data should have a special look, for example, presented by video, photos, screenshots and so on. When taking digital information, you must comply with the established laws.
During the investigation of the criminal case, it is necessary to keep records of electronic information carriers. In this case, a log is started in which all devices are registered. Each is assigned an identification number.
The importance of electronic media in criminal investigations is a controversial issue to this day. Legally, such devices are not assigned to any source of evidence. From here disagreements may arise.
findings
Electronic storage media for a modern person is a real find. With the development of technology, the volume of archives that store data is becoming more and more. Every year there are new opportunities for transmitting and reading information.
