Answer:
an immediate.
Explanation:
It is because of the instruction encoding and decoding.Intel which make these instructions decided not include instructions which provide no real advantage. MOV segment register is one of them because segment register need not to be changed very often.This saves the space in instruction encoding.
Answer: In the MOV instruction both operands i.e., source and the destination cannot be immediate operands.
Explanation:
The destination operand must be in data alterable mode and it cannot be an an immediate operand, or a segment register. Basically, the mov operation are used to copy the values stored in one registers to another registers. It can be used to load a small integer in the register.
