๐ Quick Study Guide
- ๐ง High-Level Languages (HLLs): These languages are closer to human language, making them easier to read, write, and maintain. They offer significant abstraction from hardware details.
- ๐ป Key Characteristics of HLLs:
- ๐ Readability: Syntax is often intuitive and resembles natural language.
- ๐ Portability: Code can typically run on different machine architectures with minimal changes, thanks to compilers/interpreters.
- ๐ก๏ธ Abstraction: Programmers don't need to manage memory directly or understand specific CPU registers.
- ๐ Development Speed: Faster development cycles due to built-in functions and simpler syntax.
- Examples: Python, Java, C++, C#, JavaScript.
- โ๏ธ Low-Level Languages (LLLs): These languages are closer to machine code, providing direct control over computer hardware. They are machine-dependent and require a deep understanding of the computer's architecture.
- โก Key Characteristics of LLLs:
- ๐ Hardware Control: Direct access to memory and CPU registers.
- ๐จ Execution Speed: Programs written in LLLs often execute faster and are more memory-efficient.
- โ ๏ธ Complexity: More difficult to read, write, and debug. Prone to errors if not handled carefully.
- ๐ซ Portability: Code is typically specific to a particular processor architecture.
- Examples: Machine Language (binary code), Assembly Language.
- ๐ Translators:
- Compiler: Translates HLL code into machine code before execution (e.g., C++, Java).
- Interpreter: Translates and executes HLL code line by line during execution (e.g., Python, JavaScript).
- Assembler: Translates Assembly Language into machine code.
