Logic gates are the structural building blocks of digital circuits, implementing basic Boolean functions:

Act as digital data selectors. A MUX routes one of several data inputs to a single output line based on control signals. Decoders: Take a binary code of inputs and activate one unique output out of 2n2 to the n-th power
Logic gates, when combined, create designed to perform specific tasks. These circuits fall into two main categories: [Source Code] -> (Lexical Analysis) -> (Syntax Analysis)
The modern computer is a marvel of layered abstraction. At the lowest level, billions of microscopic switches manipulate electrical currents. At the highest level, complex software runs global networks, simulates realities, and automates human tasks. Understanding this remarkable transition requires journeying through the entire computing stack.
