11 Questions
What is addressing mode concerned with?
Organizing the bits of an instruction to define the operand addresses
Which of the following is NOT a common addressing technique?
Parallel
What does immediate addressing involve?
Having the operand present in the instruction itself
What is the advantage of immediate addressing?
Avoiding the need for memory references to obtain operands
What does EA stand for in addressing modes?
Effective Address
What is the main disadvantage of immediate addressing?
Has a limited address range
How does register addressing differ from direct addressing?
It refers to a register instead of a memory address
What is the advantage of register addressing over direct addressing?
Requires no memory reference
In indirect addressing, what does the address field refer to?
A word in memory containing the operand's address
How does register indirect addressing compare to indirect addressing in terms of memory references?
Requires two memory references
Why is direct addressing simpler compared to other forms of addressing?
Directly uses the effective address as the operand's address
This quiz covers the different addressing modes used in computer architecture to define operand addresses and operations in instructions. It explains common techniques such as Immediate, Direct, Indirect, Register, Register Indirect, Displacement, and Stack addressing. Effective address, which is the address of the operand/target address in instructions, is also discussed.
