The Von Neumann architecture

The Von Neumann architecture is a design model for general purpose computing machines that uses shared memory for instructions and data and is the basis of modern computer architecture. It has four parts: the arithmetic logic unit (ALU) that performs all arithmetic operations and comparisons, the control unit (CU) that fetches and decodes instruction and data from the memory before passing the proper command for the ALU to execute or passes information to the I/O controllers, the memory that stores instructions and data, and the input/output devices.
