MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -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-2: -the program counter (PC) holds the memory address of the next instruction to be fetched from primary storage. the memory address register (MAR) holds the address of the current instruction that is to be fetched from memory, or the address in memory to which data is to be transferred.

Detailed explanation-3: -The von Neumann architecture The processor can then access the instructions and data required for the execution of a computer program using dedicated connections called buses – an address bus which is used to identify the addressed location and a data bus which is used to transfer the contents to and from a location.

Detailed explanation-4: -Modern computers are based on the von Neumann architecture in which computation and storage are physically separated: data are fetched from the memory unit, shuttled to the processing unit (where computation takes place) and then shuttled back to the memory unit to be stored.
