I really try to understand Von Neumann architecture, but one thing I can not understand is that user How can I know the number in the computer's memory if it is a command or is this data?
I know that there is a 'concept of stored program', but I have not understood anything ...
Can someone explain me in two sentences?
> Thnx!
Just keep, the user can not see the memory address and can determine whether it is the command or the data It can be both.
All in its interpretation; If the memory address points, it will be interpreted as an order. If it is referred to by reading instructions, then this data is there.
The flexibility of this is that a program can write programs (or rewrite) in memory, which can be executed by setting program counter at the initial address.
The modern operating system The limit of this behavior is being interpreted as commands, by keeping parts of memory
