Information processes. Information. Information processes A17. What files are infected by macro viruses?

Properties of information are nothing more than signs of information - its qualitative characteristics.

These properties are closely interrelated:

  • objectivity - subjectivity,
  • reliability - unreliability,
  • completeness - incompleteness,
  • relevance - irrelevance,
  • value - uselessness,
  • clarity - incomprehensibility.

Objectivity. Information is objective if it does not depend on anyone’s opinion or judgment.

Example. The message “It’s warm outside” carries subjective information, and the message “It’s 22 degrees Celsius outside” carries objective information (if the thermometer is working). Objective information can be obtained using working sensors, measuring instruments. But, reflected in the consciousness of a particular person, information ceases to be objective and becomes subjective, since it is transformed depending on the opinion, judgment, experience, and knowledge of a particular subject.

Credibility. Information is reliable if it reflects the true state of affairs.

Example. While talking on the phone, noise interferes with hearing the interlocutor, which makes it impossible to accurately perceive the information; in this case, the information will be unreliable. Objective information is always reliable; but reliable information can be both objective and subjective. Reliable information helps us make the right decision. Information may be inaccurate for the following reasons:

  • deliberate distortion (disinformation);
  • distortion due to interference (“damaged phone”);
  • unintentional distortion (rumors, stories, fishing stories).

Completeness. Information can be called complete if it is sufficient to understand the situation and make a decision. For example, the historian’s dream is to have complete information about past eras. But historical information is never complete, and the completeness of information decreases as the historical era moves away from us. Even events that took place before our eyes are fully documented, much is forgotten, and memories are distorted. Incomplete information may lead to an erroneous conclusion or decision.

Relevance(timeliness) of information is important, material for the present time.

Example. The message “It’s raining outside now” is relevant to a person who is going to go outside, but not relevant to a person who is going to stay at home. Only timely information received can bring the necessary benefits, for example, warnings about earthquakes, hurricanes, and other natural disasters. Information may be outdated for two reasons: it may be outdated (last year's newspaper) or insignificant, unnecessary (for example, a message that prices in Italy have been reduced by 5%).

Usefulness or uselessness. Since there is no boundary between these concepts, we should talk about the degree of usefulness in relation to the needs of specific people. The usefulness of information is assessed by the tasks that we can solve with its help.

Example. The message “There will be a math test tomorrow” is useful for a student - he can prepare, but it is useless to him if he has a fever and does not go to school.

The most valuable information for us is quite useful, complete, objective, and reliable. At the same time, let us take into account that a small percentage of useless information even helps, allowing you to rest on uninformative sections of the text. And the most complete, most reliable information cannot be new.

Understandability. Information is understandable if it is expressed in a language understandable to the recipient.

Example. Music notation for a music school student carries clear information. But for a student unfamiliar with musical notation, this information will simply be incomprehensible.
