The (Not-AND) and NOR (Not-OR) gates are called universal gates. You can build any other type of logic gate, and therefore an entire computer, using only NAND or only NOR gates. This simplifies physical manufacturing. 2. Building Complexity: Digital Circuits
Defines what the processor can do (e.g., x86 for PCs, ARM for phones).
: The compiler analyzes the IR to make the code run faster or consume less power. It removes dead code, reorganizes loops, and pre-calculates static values. The (Not-AND) and NOR (Not-OR) gates are called
A computer is a digital system that consists of:
: Breaks the raw source code text into a stream of meaningful units called tokens (like keywords, variables, and operators). It removes dead code, reorganizes loops, and pre-calculates
: The compiler checks the tokens against the grammatical rules of the language and builds a tree structure called an Abstract Syntax Tree (AST) .

: Learn how basic logic gates like AND, OR, and NOT are constructed from transistors. Combinatorial & Sequential Circuits
Performs mathematical calculations and logical comparisons.
Directs the flow of data and tells the ALU and memory how to respond to instructions.
