Prepare for this practice
Understand the Von Neumann architecture, the Fetch-Decode-Execute instruction cycle, internal CPU components, memory hierarchies, and multi-core processing.
Review Computer basics and the CPU before starting →Ideas to recall
- The Von Neumann architecture unifies program instructions and working data within a single shared memory system.
- The CPU executes software through the continuous Fetch-Decode-Execute machine cycle.
- The Control Unit directs data paths, while the ALU executes arithmetic and boolean operations.
- The memory hierarchy balances high access speed near the CPU with large non-volatile storage capacities.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
