A programming language is a formal set of instructions that allows humans to communicate with computers and create software applications. Programming languages are typically categorized into generations based on their abstraction level:
-
First-generation languages (1GL) are low-level, machine languages that consist of binary code directly executed by the computer's hardware.
-
Second-generation languages (2GL) are assembly languages that use symbolic representations of machine code, making them slightly easier to read and write.
-
Third-generation languages (3GL) are high-level languages like Python, Java, and C++, which provide more abstraction and are closer to human languages.
-
Fourth-generation languages (4GL) are even more abstract, often used for specific tasks such as database queries and report generation, focusing on what to do rather than how to do it.
