Definition - What does Boolean mean?
Boolean refers to a system of logical thought that is used to create true/false statements. A Boolean value expresses a truth value (which can be either true or false). Boolean expressions use the operators AND, OR, XOR and NOT to compare values and return a true or false result. Boolean logic was developed by George Boole, an English mathematician and philosopher, and has become the basis of modern digital computer logic.
Techopedia explains Boolean
Because computer operate in binary, computer logic can often be represented in Boolean terms. For example, Boolean logic may describe computer circuit states that are charged (1, or true) or not charged (0, or false). This describes the basic binary concept upon which computer processing is based. Boolean logic is also commonly seen when performing Web searches on a search engine. For example, if a person is searching for a document that contains both the words "Boolean" and "computer science", a search phrase might be created using the Boolean operator "and": "Boolean and computer science." In this case, the operator "and" tells the search engine that it should be seeking results that contain both terms. Similarly, the search phrase "Boolean not computer science" will tell the search engine to seek results that contain the first term but omit results that include both terms.
