Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1]
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .
The SAP architecture serves as an example in Digital Computer Electronics for building and analyzing complex logical systems with digital electronics. Digital Computer Electronics successively develops three versions of this computer, designated as SAP-1, SAP-2, and SAP-3. Each of the last two build upon the immediate previous version by adding ...
Prior to the advent of digital computers, the electronics and other engineering disciplines used the terms system and hardware as they are still commonly used today. However, with the arrival of digital computers on the scene and the development of software engineering as a separate discipline, it was often necessary to distinguish among ...
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks.
Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 [1] and extended in 1972. [2] The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities.
The storage of computer programs is key to the operation of modern computers and is the connection between computer hardware and software. [7] Even prior to this, in the mid-19th century mathematician George Boole invented Boolean algebra —a system of logic where each proposition is either true or false.
