Programming Languages for Tech+

Programming languages can be grouped by level and execution model: - Low-Level vs High-Level: - Low-level: Close to machine code. Machine code (0s and 1s). Assembly language (human-readable mnemonics). Give fine control over hardware but difficult to write. - High-level: Closer to human language (Python, Java, C#, JavaScript). Abstract away hardware details, generally portable, easier to use. - Compiled vs Interpreted: - Compiled: Compiler translates entire source code to machine code before execution (C, C++, Go). Results in executable file. Faster execution, no source code needed to run.
