How did the concept of a stored-program architecture contribute to the advancement of computing devices like EDVAC?
The concept of a stored-program architecture allowed instructions and data to be stored in the same memory of the computer. This innovation was crucial because it enabled computers like EDVAC to be more versatile and programmable. Prior to this concept, computers like ENIAC required physical rewiring to change the instructions they executed.
With stored-program architecture, instructions could be written as data and stored in memory, making it possible to change the program without altering the hardware. This significantly streamlined the programming process and laid the foundation for the modern programmable computer.
