- Von-neumann machine - also known as von Neumann architecture or Princeton architecture refers to a computer architecture, described by John Van Neumann in 1945. This architecture refers to multiple Registers such as-
• Memory Address Register (MAR): Fro storing memory locations on instructions.
• Memory Data Register (MDR): For storing instructions fetched from memory.
• Current Instruction Register (CIR): For storing most recently fetched instructions.
• Instruction Buffer Register (IBR): For storing the instruction that is not to be executed immediately.
• Program Counter (PC): For keeping track of memory locations.
