A programming language is a standardized and structured language designed to be used by humans to write instructions that a computer can understand and execute. It provides a set of rules and symbols, as well as a syntax, that allows a programmer to express their ideas and solutions in a way that the computer can understand.
There are many different types of programming languages, including low-level languages, such as Assembly and C, high-level languages, such as Python, Java, and Ruby, and domain-specific languages, such as SQL and HTML. Each programming language has its own strengths, weaknesses, and areas of use, and programmers often choose a specific language based on the task or project they are working on.
The role of a programming language is to serve as a bridge between the human and the computer, providing a way for the programmer to express their ideas and solutions in a way that the computer can understand. A programmer writes code in a programming language, and that code is then translated into machine code by a compiler or interpreter, so that the computer can execute the instructions.
