FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Von Neumann Architecture is a digital computer architecture whose design is based on the concept of stored program computers where program data and instruction data are stored in the same memory.

Detailed explanation-2: -Von Neumann architecture is based on the stored-program computer concept, where instruction data and program data are stored in the same memory. This design is still used in most computers produced today.

Detailed explanation-3: -The “classical” von Neumann architecture consists of main memory, a central-processing unit (CPU) or processor or core, and an interconnection between the memory and the CPU. Main memory consists of a collection of locations, each of which is capable of storing both instructions and data.

Detailed explanation-4: -Harvard Architecture is the computer architecture that contains separate storage and separate buses (signal path) for instruction and data. It was basically developed to overcome the bottleneck of Von Neumann Architecture.

Detailed explanation-5: -Instructions and data are held in separate units of main memory. It uses registers to help prevent slowing down the fetch-decode-execute cycle. The memory address register holds the address in main memory that is currently being read or written.
