1. Logic Gates: The Basic Building Blocks
This guide outlines the journey from basic electronic switches to complex computer systems, covering the essential layers of hardware and software.
Digital circuits are composed of logic gates connected together to perform specific functions. There are two main types of digital circuits: Lexical Analysis: The compiler breaks source code into
- Lexical Analysis: The compiler breaks source code into tokens (keywords, variables, operators).
- Syntax Analysis (Parsing): Checks if the tokens follow the grammar rules of the language. It builds a "parse tree."
- Semantic Analysis: Checks for logical meaning (e.g., ensuring a variable is declared before use).
- Intermediate Code Generation: Creates an abstract, machine-independent code.
- Optimization: Improves the code to run faster or use less memory (e.g., removing dead code that never runs).
- Code Generation: Translates the optimized intermediate code into specific assembly language or machine code for the target processor.
