Computer structure refers to the various parts of the computer, which are organized in such a way that makes it possible to communicate with the computer. It can be categorized into five main parts, including input devices, memory, output devices, central processing unit, and input and output ports. Input devices take command from the user and enter data in the system, whereas output devices display results after processing data in forms such as hard copy, soft copy, and video or voice. Central processing unit regulates the functioning of the computer using arithmetic logic unit, register and control unit. Memory is the storage medium, and input and output ports are connectors controlled by the processor for managing input and output actions. Verification is the process of determining whether or not a software system meets the required specifications and standards and serves its intended purpose. This book provides comprehensive insights into analysis, integration and verification of computer structures and software. It is a resource guide for experts as well as students.

Software is a set of instructions that tells a computer how to operate. This is different from hardware, which is the actual component that does the real work. A software system is a system of interconnected software components that make up a computer system. Major categories of software systems comprise programming software, application software development, and system software. A few examples of software systems include database management systems, computer reservations systems, embedded systems, content management systems, and operating systems. A computer program refers to a set of instructions written in a programming language that a computer can execute or understand. Source code is the human-readable version of a computer program. Compilers are used to convert source code into machine instructions creating an executable file. This book contains some path-breaking studies on the theories and methods related to computer programs and software systems. It will serve as a reference to a broad spectrum of readers.
