MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In a normal computer that follows von Neumann architecture, instructions and data both are stored in the same memory. So same buses are used to fetch instructions and data.

Detailed explanation-2: -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-3: -data and instructions are both stored as binary . data and instructions are both stored in main memory. instructions are fetched from memory one at a time and in order-serially. the processor decodes and executes an instruction, before cycling around to fetch the next instruction.

Detailed explanation-4: -Von-Neumann Architecture comprised of three major bus systems for data transfer. Address Bus carries the address of data (but not the data) between the processor and the memory. Data Bus carries data between the processor, the memory unit and the input/output devices. Control Bus carries signals/commands from the CPU.

Detailed explanation-5: -The von Neumann architecture-also known as the von Neumann model or Princeton architecture-is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC.
