There are three types of domain meanings: Chinese, mathematics, and computer vocabulary.

1. In Chinese

Domain is a first-level Chinese character with a general standard of Chinese. The ancient writing of the domain is "or" (yù)", the left is like a region, and the right is the "ge" used for guarding. It is about to divide the "domain" next to the "soil" of the seal text.

The original meaning of the differentiation word "is" or "domain refers to a place within a certain boundary, and by extension, it refers to a feudal province and a feudal country.

Second, in mathematics

The set of numbers, including all positive and negative integers and positive and negative fractions, is called a rational number, and the range of numbers extends to this point, within which addition, subtraction, multiplication, and division can be performed freely. This set of numbers that can be freely added, subtracted, multiplied, and divided is called a field. Therefore, it can be said that all rational numbers constitute the domain.

Although all rational numbers make up a domain, a domain does not refer only to rational numbers. In addition to rational numbers, there are also irrational numbers. Rational and irrational numbers together make up real numbers, and all real numbers also make up domains.

3. Computer vocabulary

A domain is a computer-specific term that refers to a unit that operates independently in a Windows network. Domains have different meanings in different systems and software: domains are both the logical organizational units of the Windows network operating system and the logical organizational unit of the Internet, and in the Windows network operating system, the domain is the security boundary.

In the file system, a domain is sometimes referred to as a "field" and refers to the basic unit of data that cannot be reorganized. In a Word document, a field is a type of data that can change, and it is one of the most useful features of Word.

Characteristics of the domain in the computer:

A domain is an independent unit in the Windows network, and a trust relationship is required to access each other. A trust relationship is a bridge between domains. When a domain establishes a trust relationship with other domains, the two domains can not only manage each other as needed, but also allocate device resources such as files and printers across the network, so that network resources can be shared and managed between different domains.

Meaning: A place within a certain boundary: extraterritorial. Exotic. Region. Regional. Field. Territory.
