Fourth-generation refers to the latest phase in the evolution of technology, particularly in computing and telecommunications. This generation is characterized by the use of advanced microprocessors, which enable faster processing speeds and improved efficiency. It also includes the development of integrated circuits, allowing for more compact and powerful devices. In the context of programming languages, fourth-generation languages (4GL) are designed to be more user-friendly and closer to human language than their predecessors. They aim to simplify the coding process, making it easier for developers to create applications and manage databases, thus enhancing productivity in software development.
