Detailed explanation-1: -Von Neumann architecture is the design upon which many general purpose computers are based. The key elements of von Neumann architecture are: data and instructions are both stored as binary digits. data and instructions are both stored in primary storage.
Detailed explanation-2: -Which of the following statements are true for von Neumann architecture? a)shared bus between the program memory and data memoryb)separate bus between the program memory and data memoryc)external bus for program memory and data memoryd)external bus for data memory onlyCorrect answer is option ‘A’.
Detailed explanation-3: -In the classical von Neumann architecture the ALU and the control unit are connected to a single memory that stores both the data values and the program instructions.
Detailed explanation-4: -Von Neumann architecture is based on the stored-program computer concept, where instruction data and program data are stored in the same memory.
