Machine code and assembler. How to read the code?

Question

assembler

Can you suggest how to read these lines. The teacher can point to any line and say read. I searched the Internet for information about this, but did not find it. Maybe I didn't search well.
If there are lectures on this subject, I will be grateful. Particularly interested in column 6

Answer 1

5th column - labels for the transition, 6th column - instruction mnemonics, 7th - operands
Previous columns - the serial number of the program line and the actual machine opcodes
Open the instructions of the target processor (which you did not specify, by the way, how and which one assembler is used) - yes, you interpret ...
HALT - command to suspend the processor until waiting for an interrupt
MOV - transfer data from one operand to another ...
etc.
Basically, nothing complicated.
