Here's a breakdown:
Why do we need computer languages?
* Computers don't understand human language: They only understand a very basic set of instructions, like "add these numbers" or "store this data".
* Languages bridge the gap: Computer languages translate human instructions into a form the computer can understand.
Types of computer languages:
* Low-level languages: These languages are very close to the machine's language. They're difficult to write but very efficient.
* Machine language: This is the most basic form, using only binary digits (0s and 1s).
* Assembly language: This is slightly more human-readable, using mnemonics (short codes) for instructions.
* High-level languages: These are closer to human language and are easier to learn and write. They are more abstract and need to be translated into machine code before the computer can understand them.
* Programming languages: These are used to create software, apps, and websites. Examples include: Python, Java, JavaScript, C++, C#, and many more.
* Scripting languages: These are used to automate tasks and create simple programs. Examples include: Python, JavaScript, Bash, PowerShell.
Key concepts:
* Syntax: The set of rules that govern the structure of the language.
* Semantics: The meaning of the language's instructions.
* Compiler/Interpreter: Programs that translate high-level languages into machine code.
In simple terms:
Think of a computer language like a recipe. The instructions are the words, and the ingredients are the data. The computer follows the recipe to create the final product, which could be a program, a website, or even a video game.
