MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The Von Neumann architecture consists of a single, shared memory for programs and data, a single bus for memory access, an arithmetic unit, and a program control unit. The Von Neumann processor operates fetching and execution cycles seriously. 2.

Detailed explanation-2: -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. memory data register (MDR)-holds the contents found at the address held in the MAR, or data which is to be transferred to primary memory.

Detailed explanation-3: -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-4: -A major drawback of the Von Neumann architecture is a problem that’s commonly referred to as the “Von Neumann bottleneck.” Memory and the CPU are separated in the Von Neumann architecture, so the CPU must fetch data for every operation it performs.
