Computer engineering is a subfield of electrical engineering that combines the fields of electronics engineering and computer science required for creating computer software and hardware. The set of instructions that is stored and helps run the hardware comprise the software components. The physical parts of a computer such as mouse, the central processing unit (CPU), storage, and printer are the hardware components. The main activities of computer engineering include designing, developing and testing computer hardware and software. They also analyze and evaluate the results of computer testing, and update the outdated equipment so that it can become compatible to be utilized with new software or hardware. Computer engineering is further subdivided into various sub-areas including machine intelligence, embedded systems, automation, cybersecurity, networking, and software engineering. This book aims to shed light on the various software and hardware systems used in computer engineering. It traces the progress of this field and highlights some of its key concepts and applications. Those in search of information to further their knowledge will be greatly assisted by this book.
