Quiz on Addressing Modes and CPU

What does the term "addressing mode" refer to in computer architecture?

• The speed at which the CPU accesses memory

• The method used to specify the location of an operand in an instruction

• The number of bits used in a memory address

• The type of cache memory used by the CPU

Which addressing mode uses the operand value directly within the instruction itself?

• Direct addressing mode

• Indirect addressing mode

• Immediate addressing mode

• Register addressing mode

What is the primary function of the Program Counter (PC) in a CPU?

• To store the result of arithmetic operations

• To hold the address of the next instruction to be executed

• To manage input/output operations

• To store temporary data during processing

Which component of the CPU is responsible for performing arithmetic and logical operations?

• Control Unit (CU)

• Memory Management Unit (MMU)

• Arithmetic Logic Unit (ALU)

• Instruction Register (IR)

In register addressing mode, where is the operand stored?

• In the main memory

• In the instruction itself

• In a CPU register

• In the cache memory

Which of the following best describes a RISC (Reduced Instruction Set Computer) architecture?

• It uses a large number of complex instructions

• It uses a small set of simple, highly optimized instructions

• It relies entirely on microcode for instruction execution

• It uses variable-length instructions for all operations

What is the effective address in indirect addressing mode?

• The address stored directly in the instruction

• The address of the register holding the operand

• The address obtained by reading the memory location pointed to by the instruction's address field

• The address computed by adding a constant to the program counter

In relative addressing mode, the effective address is computed as:

A CPU uses a 3-stage pipeline: Fetch, Decode, and Execute. If each stage takes 1 clock cycle and there are no hazards, how many clock cycles are needed to complete 5 instructions?
