Addressing Mode- Quiz 2 by Gururaj Surampalli

Which addressing mode is used when the operand is specified within the instruction itself?

• Immediate Addressing Mode
• Relative Addressing Mode
• Register Addressing Mode
• Direct Addressing Mode

In which addressing mode does the operand's address change after every access?

• Auto-increment addressing mode
• Register addressing mode
• Indexed addressing mode
• Direct addressing mode

What is the primary characteristic of the Register Indirect addressing mode?

• The operand's address is stored in a register.
• The operand is directly specified in the instruction.
• The address is calculated using an immediate value.
• The operand's address is stored in memory.

Which addressing mode uses a base register and an offset to compute the effective address?

• Direct Addressing
• Base-Offset Addressing
• Indexed Addressing
• Relative Addressing

In the Relative addressing mode, what does the offset refer to?

• The offset is the value of the next instruction to execute.
• The offset is a fixed address in memory.
• The distance from the current instruction pointer

• The offset is the total size of the instruction set.

Which addressing mode is typically used for stack operations?

• Auto Decrement

• Indexed addressing mode
• Direct addressing mode
• Auto Increment

Which of the following is NOT a type of addressing mode?

• Indexed

• looping
• indirect addressing
• direct addressing

What does the term 'effective address' refer to in the context of addressing modes?

• The actual memory location accessed during instruction execution.
• The location of the CPU registers.
• The address of the instruction itself.
• The address finally used to access the operand

In the Indexed addressing mode, if the index register contains 10 and the offset is 5, what is the effective address?

• 5
• 10
• 20
• 15

What is the main advantage of using the Immediate addressing mode?

• Constant values directly in the instruction

• Increases complexity of instruction decoding.
• Slower access to data due to indirect addressing.
• Faster access to data by specifying the operand directly in the instruction.
