Earlier computers, such as the ENIAC, were hard-wired to do one task. Older ARM architecture used Von Neumann Architecture with RISC, and later with ARM9 they shifted to Harvard Architecture with RISC. The instruction/data held in that memory address is sent along the data bus to the MDR. E    In this case, the memory address of the new next instruction to be fetched is copied into the program counter. ➨It will have single set of address/data buses between CPU and memory. The executed instruction may require the program to jump to a different place in the program. Von Neumann architecture is composed of three distinct components (or sub-systems): a central processing unit (CPU), memory, and input/output (I/O) interfaces. What is the difference between little endian and big endian data formats? In this stored-program concept, programs and data are stored in a separate storage unit called memories and are treated the same. 26 Real-World Use Cases: AI in the Insurance Industry: 10 Real World Use Cases: AI and ML in the Oil and Gas Industry: The Ultimate Guide to Applying AI in Business: A central processor consisting of a control unit and an arithmetic/logic unit.
