What are instruction codes?

An instruction code is a group of bits that instruct the computer to perform a specific operation (set of micro- operations).

▪ Operation code is a part of instruction code; a group of bits that define such operations as add, subtract, multiply, shift, and complement..

What is the use of addressing modes?

The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually executed. The 8086 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types.
