Question

If the content of DS and BX register is 2500H and 1000H respectively. From which memory location will 8086 fetch the data while executing instruction MOV CX, [BX]

Answer 1

Moves contents from bx to cx register

Explanation:

In microprocessor 8086, we have AX, BX, CX, and DX as registers where AX is the accumulator. Registers are used to store values, perform operations. So Microprocessor use assembly language to perform the necessary function.

MOV is an instruction which "moves the contents of source register to the destination register".

MOV CX, [BX]

Here BX is the source register and CX is the destination register.

Always the last one will be the source and it will be copied to the left side register.
