: Ultra-fast, internal storage locations (e.g., Program Counter, Instruction Register).
This write-up explores the hierarchy of abstraction that allows a computer to transform human-readable code into physical electrical signals. It follows the progression from fundamental switches to complex processors and the software that controls them. 1. The Foundation: Logic Gates and Circuits

Used by Java (JVM) and C# (CLR). Compiles bytecode to native machine code during runtime , observing which paths are hot.
This binary code is stored onto a hard drive, and loaded into RAM when the program is opened. : Ultra-fast, internal storage locations (e
: Digital circuits that perform mathematical addition. A "Half Adder" adds two single binary bits. A "Full Adder" can handle a carry bit from a previous operation, allowing computers to add multi-digit binary numbers.
Every digital computational system relies on the ability to control the flow of electricity. In modern electronics, this is achieved using the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). The Transistor as a Switch Compiles bytecode to native machine code during runtime
The compiler reads the source code text file and groups characters into meaningful chunks called tokens (such as keywords, variable names, and operators).
Humans write:
: Holds the instruction currently being decoded and executed. The Control Unit (CU)
