Computer Architecture Quiz

Which CPU component performs arithmetic and logical operations?

• Control Unit (CU)

• Arithmetic Logic Unit (ALU)

• Program Counter (PC)

• Memory Address Register (MAR)

The control unit (CU) is responsible for:

• Storing intermediate results

• Fetching and decoding instructions

• Performing arithmetic operations

• Transmitting data to secondary memory

The register that holds the address of the next instruction to be fetched is:

• IR

• MDR

• PC

• AC

Which register holds the actual instruction currently being executed?

• MAR

• IR

• MDR

• AC

The bus responsible for carrying instructions and data between components is:

• Address bus

• Control bus

• Data bus

• Instruction bus

Which processor type is designed to work alongside the CPU for specialized tasks?

• Single-core

• Multi-core

• Co-processor

• Control unit

GPUs are particularly suitable for:

• File compression

• Sequential processing tasks

• Parallel processing of large computations

• Managing storage devices

A main architectural difference between CPUs and GPUs is that:

• CPUs have more cores optimized for parallel processing

• GPUs have many smaller cores for parallel tasks

• CPUs are less power efficient than GPUs in graphics tasks

Which type of memory is volatile?

• ROM

• RAM

• Flash memory

• Optical disk

Cache memory is primarily used to:

• Store the operating system

• Speed up data access for the CPU

• Back up data externally

• Hold permanent data
