![]() ![]() The von Neumann architecture describes a general framework, or structure, that a computer's hardware, programming, and data should follow. Two basic types of computer architecture are: The architectural design of a computer system is concerned with the specifications of the various functional modules, such as processors and memories, and structuring them together into a computer system. It includes the information, formats, the instruction set, and techniques for addressing memory. Digital Computers: Computer ArchitectureĬomputer Architecture is concerned with the structure and behaviour of the computer as seen by the user. This aspect of computer hardware is sometimes referred to as computer implementation. ![]() Once the computer specifications are formulated, it is the task of the designer to develop hardware for the system.Ĭomputer design is concerned with the determination of what hardware should be used and how the parts should be connected. Digital Computers: Computer DesignĬomputer Design is concerned with the hardware design of the computer. ![]() The various components are assumed to be in place and the task is to investigate the organizational structure to verify that the computer parts operate as intended. By using various coding techniques, groups of bits can be made to represent not only binary numbers but also other discrete symbols, such as decimal digits or letters of the alphabet.Ĭomputer Organization is concerned with the way the hardware components operate and the way they are connected together to form the computer system. Information is represented in digital computers in groups of bits. true or false, yes or no statements), digital components that are constrained to take discrete values are further constrained to take only two values and are said to be binary.ĭigital computers use the binary number system, which has two digits: 0 and 1. Because of the physical restriction of components, and because human logic tends to be binary (i.e. In practice, digital computers function more reliably if only two states are used. From this application the term digital computer emerged. The first electronic digital computer, developed in the late 1940s, was used primarily for numerical computations and the discrete elements were the digits. , 9, for example, provide 10 discrete values. These values are processed internally by components that can maintain a limited number of discrete states. The word digital implies that the information in the computer is represented by variables that take a limited number of discrete values. The digital computer is a digital system that performs various computational tasks. ![]()
