Physics of Information Technology

Klappentext The Physics of Information Technology explores the familiar devices that we use to collect, transform, transmit, and interact with electronic information. Many such devices operate surprisingly close to very many fundamental physical limits. Understanding how such devices work, and how they can (and cannot) be improved, requires deep insight into the character of physical law as well as engineering practice. The book starts with an introduction to units, forces, and the probabilistic foundations of noise and signalling, then progresses through the electromagnetics of wired and wireless communications, and the quantum mechanics of electronic, optical, and magnetic materials, to discussions of mechanisms for computation, storage, sensing, and display. This self-contained volume will help both physical scientists and computer scientists see beyond the conventional division between hardware and software to understand the implications of physical theory for information manipulation. Zusammenfassung In this companion volume to his highly successful Nature of Mathematical Modeling! Gershenfeld explores the devices we use to collect! transform! transmit! and interact with electronic information to help both physical and computer scientists see beyond the conventional division between hardware and software to understand implications of physical theory for information manipulation.
