Computer technology pervades almost every aspect of our life: from the cars that we drive, to the mobile phones that we use to communicate; from the digital cameras that capture images of the world around us, to the laser printers that turn image into picture. Yet at the heart of these enabling technologies lie fundamental components and systems, without the understanding of which such technologies would never have been developed. "Principles of Computer Hardware" explores the fundamentals of computer structure, architecture, and programming that underpin the array of computerized technologies around which our lives are now built. The book opens with an introduction to the fundamental concepts upon which computers are constructed - gates, circuits, logic - and computer arithmetic, the 'language' through which computers communicate. It then reveals how computers are structured and how they operate, taking us step-wise from the instruction set architecture, the bringing together of instructions through assembly language programming, and on to the heart of the computer, the central processing unit. The book then builds on these foundations to consider how the hardware interfaces with its surroundings, introducing us to topics such as computer memory; operating systems and the interface between hardware and software; and computer peripherals and computer communications - the interface with the outside world. Always putting educational value first, "Principles of Computer Hardware" uses the 68K processor as a powerful teaching and learning tool, putting substance firmly before style. With the clarity of explanation and captivating style for which Alan Clements is renowned, the book draws the student in to the heart of the subject, to foster an in-depth understanding from which more specialised study can then extend. The learning experience is enriched still further with a free CD-ROM, providing resources to enable students to engage with the subject in a hands-on manner: a Windows-based simulator for the student to explore the design of digital circuits; Windows and DOS-based 68K simulators for students to investigate the operation of the 68K processor; and an ARM simulator for students to write programs for a RISC processor, and run them on a PC.
