Indexed addressing uses an index register to modify the address of the operand, allowing for efficient access to arrays or tables by adding an offset to a base address. In contrast, based addressing uses a base register to provide a starting point for address calculation, typically for accessing data structures relative to a fixed memory location. Essentially, indexed addressing focuses on dynamic offsets for array elements, while based addressing relies on a static reference point. Both methods enhance memory access flexibility, but they serve different purposes in addressing schemes.

What are the different data addressing modes available in 8086?
The 8086 microprocessor supports several data addressing modes, including immediate, direct, indirect, indexed, and based addressing modes. In immediate addressing, the operand is specified directly in the instruction. Direct addressing involves providing the memory address of the operand. Indirect addressing uses a pointer in a register to reference the operand's memory location, while indexed addressing combines a base address with an offset from an index register. Additionally, based addressing uses a base register to locate the operand in memory.
What is indexed addressing mode?
When stored in contiguous blocks, data usually has a base address. Accessing any data from the block requires an offset to the base address which is achieved through an index. The adding of an offset to the base address is called indexed addressing.
What is the purpose of DI register in microprocessor in 8086?
DI is the Index register in Data segment(16-bit, 64 KB) .Destination Index (DI) is a 16-bit register. DI is used for indexed, based indexed and register indirect addressing, as well as a destination data address in string manipulation instructions.
What is the advantage of the indirect and indexed addressing mode?
The advantage of indirect and indexed addressing modes lies in their flexibility and efficiency for accessing data. Indirect addressing allows for dynamic memory access by using a pointer to the memory location, enabling easier management of data structures like arrays and linked lists. Indexed addressing, on the other hand, facilitates accessing elements within data structures by combining a base address with an offset, making it efficient for iterating through arrays and performing calculations with varying data sizes. Together, these addressing modes enhance program versatility and can lead to more efficient memory usage.

What type of annuity credits an individual with a return that is based on changes in an index?
This would be called an indexed annuity or an equity indexed annuity both meaning the same thing.
