In a CPU, which unit is responsible for managing data transfer between the CPU and memory?Question 2Answera.ALUb.Control Unitc.Cached.Memory Management Unit

To answer the question regarding which unit in a CPU is responsible for managing data transfer between the CPU and memory, let's analyze the options provided:

1. ALU (Arithmetic Logic Unit): This unit is primarily responsible for performing arithmetic and logic operations. It does not manage data transfer.

2. Control Unit: The Control Unit orchestrates the operations of the CPU, directing the flow of data between the CPU and other components. However, its main role is to manage the execution of instructions rather than directly handling data transfers.

3. Cache: The Cache is a small-sized type of volatile computer memory that provides high-speed data access to the processor and stores frequently used computer programs, applications, and data. While it plays a crucial role in data access, it does not directly manage data transfer.

4. Memory Management Unit (MMU): The MMU is specifically designed to handle the transfer of data between the CPU and the main memory (RAM). It translates addresses and manages memory protection, thus playing a critical role in data transfer.

Final Answer

The correct answer is d. Memory Management Unit.
