Abstract

This chapter delves into the practical implementations of classical computing, starting with the fundamental building blocks: logic gates and wires. It explains how these components form a universal gate set capable of representing any Boolean operation. The chapter also explores the physical realization of logic gates using transistors and other electronic components. Moving beyond combinational circuits, the text introduces sequential circuits, which incorporate memory elements and a clock signal to enable more complex computations. The chapter discusses the architecture of a central processing unit (CPU), including its registers, arithmetic logic unit (ALU), and control unit. It also covers the process of computer programming, from high-level languages to machine code, and the role of compilers in translating human-readable code into machine instructions. The chapter concludes with a discussion on the progress of classical computing, including Moore's Law and the limitations of current approaches, as well as the potential of parallel computing and quantum computing.
