The process of interpreting messages from others into meaning is called DECODING. Decoding has to do with conversion or interpretation of codes into meaningful forms. For communication to take place the receiver of the message must be able to decode correctly what the message is saying.

Explanation: MOV instruction copies a word or byte from a specified source to a specified destination. The destination can be a register or a memory location. The source can be a register or a memory location or an immediate number .
For MOV CX 037AH: put immediate number 037AH to CX
For MOV BL, (437AH) : copy byte in Ds at offset 437AH to BL
For MOV AX BX : copy content register BX to AX
For MOV DL, (BX) : copy byte from memory at(BX) to DL
That identifies the differences. Good luck.
