Where is the CPU located in a computer?

• On the hard drive

• Inside the RAM

• On the motherboard

• In the power supply

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

• Perform mathematical calculations

• Store data temporarily

• Fetch and retrieve instructions

• Manage input and output devices

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

• To control the flow of data

• To perform calculations and logic operations

• To store data permanently

• To manage system memory

What are registers used for in a CPU

• Managing input/output operations

• Temporary storage of data and instructions

• Executing programs

• Permanent data storage

Which of the following is the first step in the CPU’s processing cycle?

• Fetching instructions

• Decoding instructions

• Storing the result

What is the purpose of decoding in the CPU processing cycle?

• To retrieve data from memory

• To translate instructions into a form the CPU can understand

• To store data back into memory

• To perform calculations

In the CPU processing cycle, what happens during the execution phase?

• The CPU fetches instructions

• The CPU decodes instructions

• The CPU carries out the instructions

• The CPU stores the results

What is hyper-threading?

• Increasing the clock speed of a CPU

• A form of parallel processing by dividing work into multiple threads

• Combining multiple CPUs into one chip

• Reducing power consumption by the CPU

What is the benefit of hyper-threading in CPUs?

• It increases the number of physical cores in a CPU

• It allows the CPU to run multiple threads simultaneously

• It reduces the size of the CPU

• It simplifies the CPU’s architecture
