Boolean

Boolean or sometimes referred as Bool is a data type in computer programming and development originated from Boolean algebra by George Boole. This data type works on a two-state system, that is, it exists in only one of two states at any given time. Logical statements cannot be discussed without mentioning Booleans which are used together with logical operators like ‘and’, ‘or’, ‘not’. These operators enable the developers to construct more composite conditions and to direct the flow of the programs, which is why Booleans are a fundamental part of the decisions within the applications.

Boolean logic is used in many applications in algorithms, data structures, and even in the hardware design. For instance, in search engines such as Google, Boolean logic is used in searching and sorting of data by employing a query that the user has entered. Likewise, the Boolean expressions are used in smart home systems where the processes are managed mechanically based on the true/false conditions, for example, switching on the lights as there is motion. Due to its flexibility and easy usage, Boolean data type is widely used in both hardware and software where detailed control and decision are required in most of the technological fields.
