Understanding Computer Memory and CPU Functions

What is the primary function of the Control Unit (CU) in a CPU?

• To store frequently used data and instructions

• To coordinate all activities inside the CPU

• To perform arithmetic operations

• To store data temporarily

Which type of memory is used for long-term storage of files and programs?

• Primary memory

• Cache memory

• Secondary storage

• Virtual memory

What is the main purpose of cache memory?

• To store data permanently

• To improve processor performance by storing frequently used data

• To act as a backup for RAM

• To store open programs

What happens during the "fetch" stage of the Fetch-Decode-Execute cycle?

• The instruction is executed

• The instruction is decoded

• The instruction is retrieved from memory

• The instruction is stored

Which type of memory is used when there is not enough main memory (RAM)?

• Cache memory

• Virtual memory

• Secondary storage

• Primary memory

What is the role of the Arithmetic Logic Unit (ALU) in a CPU?

• To decode instructions

• To perform logical and arithmetic operations

• To store data temporarily

• To manage data flow

Which of the following is a characteristic of off-line storage?

• It is volatile

• It is used for temporary data storage

• It can be stored away from the computer

• It is faster than RAM

What is the main advantage of having more cache memory in a computer?

• It increases the computer's storage capacity

• It allows more data and instructions to be accessed quickly

• It reduces the need for secondary storage

• It improves the computer's graphics performance

Which operation is NOT performed by the Arithmetic Logic Unit (ALU)?

• Addition

• Multiplication

• Data storage

• Logical operations

What is the main purpose of virtual memory?

• To increase the speed of the CPU

• To provide additional storage space

• To act as an extension of RAM

• To store frequently used data
