What is a circuit?

The simple word “scheme” is used by many in professional fields. But sometimes it is found in everyday life. Let us further consider what a scheme is, what values ​​this word has and where it is used.

The word "scheme" has a Greek origin, the literal meaning - "appearance, form." Thus, the most general definition is: a diagram is a description or statement of something in general, main, basic features. As a rule, the image or statement itself is meant, not the drawing.

Schemes are found in various fields, and therefore the basic definition acquires new meanings based on the scope of application.

Here are some of them:

  • a drawing depicting a system, a device of something;
  • general plan, image without details;
  • a set of interrelated parts of any device, device, node;
  • an electronic device containing a plurality of components;
  • graphic model of the system.

Schemes are used in various fields. For example, there are integrated, electrical, technological schemes depicting processes that are not always possible to observe without special equipment.In computer science, the concept of a block diagram is used - such schemes are associated with information, decision-making, etc.

After people came up with the image of quite specific physical processes and phenomena, the schemes found their application at the abstract level. Such schemes are often used in psychology, mathematics, and sometimes a little in philosophy (logical scheme, metascheme, conditional scheme).
