Solution

The correct answer is Mapping

Key Points

• Mapping: ✅ Mapping refers to the process of transferring data from main memory to cache memory in a structured way. It ensures that specific blocks of memory are assigned to cache lines for faster access.
• Data exchange: ❌ Data exchange refers to the general transfer of data between two systems or components, not specifically between main memory and cache memory.
• Data transformation: ❌ Data transformation involves changing the format or structure of data, which is not relevant to this context.
• Matching: ❌ Matching refers to comparing data or finding similarities, which is not applicable to the memory transfer process.

Additional Information

• Cache Mapping Techniques: Common techniques include direct mapping, associative mapping, and set-associative mapping.
• Purpose: Mapping helps optimize data access speed by ensuring that frequently used data is stored in faster cache memory.
• Efficiency: Proper mapping reduces latency and improves the overall performance of the system.

Hence, the correct answer is: option 3) Mapping
