Programming languages are structured systems of communication that allow humans to instruct computers to perform tasks. They are essential for building software, automating processes, analyzing data, and powering digital experiences.

🧠 What Is a Programming Language?
A programming language is a formal language comprising a set of instructions that produce various kinds of output. These instructions are written using specific syntax and semantics that a computer can interpret and execute.
- Syntax: The rules that define how code must be written (like grammar in human languages).
- Semantics: The meaning behind the syntax — what the instructions actually do.
- Compiler/Interpreter: Translates human-readable code into machine code (binary) that the computer understands.
Programming languages bridge the gap between human logic and machine execution, enabling developers to build everything from simple scripts to complex systems.
