Understanding CPU Architecture and Performance

What is the primary function of the CPU in a computer system?

• To store data permanently

• To execute instructions

• To provide power to the system

• To manage network connections

Which of the following is NOT a component of the CPU architecture?

• Arithmetic Logic Unit (ALU)

• Control Unit

• Hard Disk Drive

• Registers

During the fetch-execute cycle, what is the first step the CPU performs?

• Execute the instruction

• Decode the instruction

• Fetch the instruction from memory

• Store the result

What is the role of the ALU within the CPU?

• To manage input and output operations

• To perform arithmetic and logical operations

• To store data temporarily

• To control the flow of data

Which register holds the address of the next instruction to be executed?

• Accumulator

• Program Counter

• Memory Address Register

• Instruction Register

What is the purpose of cache memory in a CPU?

• To store data permanently

• To increase the speed of data access

• To manage network connections

• To provide additional storage space

Which of the following best describes pipelining in CPU architecture?

• Executing multiple instructions simultaneously

• Storing data in multiple locations

• Fetching data from the hard drive

• Increasing the size of the cache

What is the function of the Control Unit in the CPU?

• To perform calculations

• To decode instructions and control the execution

• To store data

• To manage power supply

Which of the following is a common method for measuring CPU performance?

• Clock speed

• Screen resolution

• Hard drive capacity

• Network bandwidth

What is the main advantage of using pipelining techniques in CPUs?

• Reduced power consumption

• Increased instruction throughput

• Lower production cost

• Enhanced data security
