These individual logic gates are the building blocks of , the intricate networks that form the foundation of computing devices. Single logic gates are combined to create more complex, reusable combinatorial circuits that perform specific functions, such as decoders , encoders , and multiplexors (MUX). A MUX, for instance, selects one of several input signals and forwards it to a single output line, a crucial operation in data routing. By combining these elements, we create circuits that can add numbers (adders), store a single bit of data (flip-flops), and eventually, the more complex components of a processor.
This chapter explains how gates are combined to perform math and memory.
Transports the actual data between the CPU, memory, and devices.

The target keyword essentially describes the entire digital hierarchy. Understanding a computer is not merely about learning one specific skill; it is about grasping how a piece of software written in C++ is translated into the physical manipulation of electrons on a silicon chip. This vertical understanding is the hallmark of a well-rounded computer scientist or electrical engineer.
