Verified Answer
Match the pairs in the following questions:(A) Base addressing (...
(A) Base addressing - Position independent (By changing value in Base register location of address can be changed)
(B) Indexed addressing - Array
(C) Stack addressing - Reentranecy (Whenever code happens to be used again, address need not be the same)
(D) Implied addressing - Accumulator (If an address is not specified, it is assumed/implied to be the Accumulator)

Understanding the Addressing Modes
In computer architecture, addressing modes are crucial for determining how the operands of instructions are accessed. Let's analyze each addressing mode and its corresponding match:
Base Addressing (s) - Position Independent
- Base addressing uses a base register to determine the effective address of the operand.
- This method is often used in position-independent code, allowing programs to execute regardless of their memory address.
Indexed Addressing (r) - Array
- Indexed addressing adds a constant value to a base address using an index register.
- It is ideal for accessing elements in an array, where each element's address is calculated based on the base address of the array.
Stack Addressing (p) - Reentrancy
- Stack addressing refers to the use of a stack structure to manage function calls and local variables.
- It supports reentrancy, allowing functions to be interrupted and called again without corrupting the data.
Implied Addressing (q) - Accumulator
- Implied addressing does not require an explicit address; it uses a default register, often the accumulator.
- This makes it efficient for operations that directly manipulate the accumulator without needing to specify operands.
Correct Pairing Explanation
- The correct pairs outlined in option 'A' accurately reflect the relationships between the addressing modes and their corresponding concepts:
- A-S: Base Addressing - Position Independent
- B-R: Indexed Addressing - Array
- C-P: Stack Addressing - Reentrancy
- D-Q: Implied Addressing - Accumulator
These associations illustrate how each addressing mode aligns with specific programming and architectural concepts, making option 'A' the correct choice.
