CPU Components

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

• To synchronize related components by generating pulses

• To provide fast access to frequently used instructions and data

• To carry out calculations and make logical decisions

• To control how data moves around the CPU

What role does the Control Unit play within the CPU?

• It performs calculations and logical decisions

• It stores frequently used instructions and data

• It sends signals to control how data moves around the CPU

• It holds the address of the next instruction to be executed

What is the purpose of cache in a CPU?

• To synchronize the operations of the CPU

• To store the address of the next instruction

• To provide fast access to frequently used data and instructions

• To transmit data and instructions from one component to another

What does the clock component do in a CPU?

• Generates pulses at a constant rate to synchronize components

• Stores the address where data needs to be read from or written to

• Carries out calculations and logical decisions

• Controls how data moves around the CPU

What are registers in a CPU?

• Collections of wires through which data is transmitted

• Tiny, super fast pieces of onboard memory with specific purposes

• Units that generate pulses to synchronize CPU operations

• Small amounts of very fast memory for frequently used data

What is the generic concept of a bus in a computer system?

• A small, fast memory inside the CPU

• A component that carries out calculations

• A collection of wires for transmitting data and instructions

• An electronic unit that generates pulses

What is the function of the Program Counter register?

• It synchronizes the operations of the CPU

• It holds the address of the next instruction to be executed

• It stores the data fetched from memory

• It controls how data moves around the CPU

What does the Memory Address Register (MAR) hold?

• The data to be written back to memory

• The address in memory where data needs to be read from or written to

• The next instruction to be executed

• Frequently used instructions and data

What is stored in the Memory Data Register (MDR)?

• The address in memory for data or instruction access

• The address of the next instruction

• Either the data or an instruction fetched from memory

• Temporary values for CPU operations

What is the purpose of the Accumulator in a CPU?

• To synchronize the operations of the CPU

• To store temporary values before being written to or from memory

• To store the address for data or instruction access

• To hold the address of the next instruction
