Answer 1

Answer:

Indexed addressing mode

Explanation:

There are various addressing modes :-

1) Indexed addressing mode

2) Base Register addressing mode

3) Relative address mode

4) Displacement mode

Indexed addressing mode is best suited to access elements of an array of contiguous memory location. In Indexed addressing mode,  operand offset is data of an index register SI or DI.

Answer 2

Indexed addressing mode is best suited to access elements of an array of contiguous memory location.

Explanation:

• Addressing modes are used for referring the way the operand of an instruction has been specified.  

• In Indexed addressing mode, the address of the operand can be obtained by adding the contents as a constant value of the general register also known as index register.  

• Both the constant value and the number of the index register are given in instruction code.  

• It is mainly used for accessing the array of elements present in subsequent memory location.
