What is the function of the Memory Data Register (MDR)?

• Holds the address in memory to be accessed

• Temporarily stores data being transferred to/from memory

• Stores final calculation results

• Controls the system clock

What is the purpose of cache memory?

• To store frequently accessed instructions and data
