When would you use Indirect addressing?

• A. To manipulate multiple registers
• B. When register locations change dynamically
• C. For constant values only
• D. To ensure faster access

Answer: (B)

Using indirect addressing is particularly advantageous when register locations change dynamically. This means that the specific addresses where data is stored can vary during the program's execution. Indirect addressing allows the program to reference a register's address indirectly through a pointer or an index, enabling flexibility in accessing data regardless of its location in memory at any given time. This method is essential in scenarios where data locations may need to be modified or if data is organized in a structure that requires dynamic access. It allows the program to adapt to changes efficiently, making it particularly useful in applications that involve dynamic data structures, such as linked lists or arrays. In contrast, manipulating multiple registers is typically associated with direct addressing schemes or specific instructions designed for bulk operations. Constant values do not require indirect addressing as they are fixed and easily accessed through direct referencing. Similarly, faster access is generally achieved through direct addressing rather than indirect, as the latter may introduce additional steps to resolve the actual address before accessing the data. Hence, indirect addressing is primarily utilized for situations where flexibility and dynamic data management are critical.
