The basic idea of ​​von Neumann's machine:
1 Separation of operation and storage
2 Stored program: Instructions and data have been stored in the memory in advance, can be searched by address, and executed continuously and automatically
3 Five major components: arithmetic unit, controller, memory , Input device and output device
4 Instructions and data are represented in binary, instructions are composed of opcodes and address codes
5 Centered on the operator, the controller is responsible for interpreting the instructions, and the operator is responsible for executing the instructions
