What is the purpose of the Control Unit (CU)?

• To perform calculations

• To control the execution of instructions

• To manage the cache

• To store data

What does the Arithmetic Logic Unit (ALU) do?

• Controls data flow

• Performs calculations and logical comparisons

• Stores instructions

• Having multiple CPUs on a single chip

• Using multiple threads in a single core

What is the purpose of the processor cache?

• To store all data permanently

• To speed up access to frequently used instructions

• To replace RAM

• To manage power consumption

What is the main difference between L1 and L2 cache?

• L1 is faster than L2

• L1 is used for secondary storage

• L2 is built into the CPU

• L1 is larger than L2

What is the function of RAM?
