Stored-program concept, Storage of instructions in computer memory to enable it to perform a variety of tasks in sequence or intermittently.
Stored-program concept is designed by Hungarian mathematician John Von Neumann.
The von Neumann architecture is a design model for a stored-program digital computer that uses a processing unit and a single separate storage structure to hold both instructions and data.
A stored-program digital computer is one that keeps its programmed instructions, as well as its data, in read-write, random access memory (RAM).
Before any data are processed, instructions are read into memory. The processing starts with the first instruction in the program, which is copied into a control unit circuit. The control unit executes the instructions sequentially until it finds one that causes it to break the sequence and go elsewhere in the program.
Input/output and processing are performed simultaneously.
