Name the addressing mode used by the source operand of Instruction 4. Name the addressing mode used by the destination operand of Instruction 5 What is the machine code the assembler created to encode code the assembler created to encode assembly language Instruction 7? How many bytes of memory are required to store the complete program (express the answer in decimal form)?

Explanation / Answer

1. direct addrssing mode

2. register indirect addressing mode

3. relative base indexed addressing mode

4. The source code is created which will then translate assembly language code to executable machine code.
