Identify original text, assembled code and machine code in QtSPIM simulator

Question

I am using QtSPIM to learn assembly language. An screenshot of PC SPIM text segment

How can I identify which part of this line is the original text, assembled code and machine code? What are the major difference between assembled code and machine code?

I have used ChatGPT and it gives me the same answer as below: Assembled Version (Machine Code): 0x8fa40000 Machine Code Version (Hexadecimal): 0x8fa40000

Answer 1

Each line is one 32-bit machine code instruction.

The part in []s is the memory address for the insrtuction.

After is a hex value of the instruction encoding, which we would call the machine code instruction.

Following is a disassembly of that instruction.

And finally, the source code assembly.
