- **Caution**: 

### Q: What is the primary function of an Arithmetic Logic Unit (ALU) in computer hardware?
**A**: The ALU is the fundamental computational component that executes arithmetic operations (like addition and subtraction) and logical operations (like AND, OR, XOR) on binary data within a microprocessor or ASIC.

### Q: What materials are typically used in manufacturing an ALU?
**A**: ALUs are primarily fabricated using silicon as the semiconductor substrate, doped silicon to form transistors, metal layers for interconnects, and dielectric materials for insulation between conductive layers.

### Q: What are the key components in an ALU's Bill of Materials (BOM)?
**A**: Essential ALU components include adder/subtractor circuits for arithmetic operations, logic gate arrays for logical functions, multiplexers (MUX) for data routing, and status flag registers to indicate operation results like overflow or zero.
