Attempted by 140 students.
Show answer & explanation
Correct answer: B
Harvard architecture refers to a computer or microcontroller organization in which program instructions and data are kept in separate memory spaces. Because instruction fetch and data access use separate paths, they can often be performed more efficiently than in a single-memory von Neumann organization. Therefore, the correct option is the architecture with separate memory for instructions and data.
