Converts the parsed structure into a universal, machine-independent low-level representation.

: The source code is converted into a universal, machine-independent low-level representation (Intermediate Representation, or IR).

Analyzes the intermediate code to make it faster, use less memory, or require fewer processor cycles.

Computers can be classified into several types, including: Computers can be classified into several types, including:

Assembly language replaces binary instructions with short, human-readable text abbreviations called . Machine Code (Example) Assembly Mnemonic 10001101 MOV Add Values 00000101 ADD 00111001 CMP

Ultra-fast, internal storage slots used to hold immediate data, instruction addresses, and status flags. The Program Counter (PC) is a vital register that keeps track of the memory address of the next instruction to execute.

The compiler checks for logical errors, such as trying to add a word to a number or using an undeclared variable. The compiler checks for logical errors, such as

Universal gates used to build any other type of logic circuit. 2. Combining Gates: Integrated Circuits

To remember data, computers require memory. Sequential circuits use feedback loops to store states, meaning the output depends on both current inputs and past states.

The Control Unit translates the binary instruction to figure out what operation needs to be performed and what data is required. such as NAND

These basic gates can be combined to create more complex gates, such as NAND, NOR, XOR, and XNOR. Logic gates are used to build digital circuits, which are the foundation of modern electronics.

The CU breaks down the instruction to determine what hardware components are required.

The Central Processing Unit (CPU) is a massive collection of circuits synchronized by a clock signal. It executes instructions (machine code) to perform computations.
