The von Neumann architecture describes a general framework, or structure, that a computer\'s hardware,programming, and data should follow. It is an abstract model for computer architecture: it assumes that execution work by decoding an instruction then getting the operands and computing the result then also writing the result back to memory and finally it will repeat these thinsg again and again. So he has given a very simple structure without the actual implementations. So the whole computer is to two be divided in main 4 parts which actually are the 4 funtions that a computer will do i.e. it will have to take input so input devices, then it will do some processing hence the CPU then this result might be stored in Memory or given as output to Output devices. So by this architeture anyone can understand basic computer.
