The copying of contents from one segment register to another is not permissible. AL is then copied to the location pointed the obtained address.
Far jump is same as the direct jump, It requires five bytes to store the entire instruction.
The displacement is added to the segment address using modulo 16 addition. The direct jump is often called as far jump because it can jump to any memory location for the next instruction. In real mode the range of far jump is the first 1M byte of memory. In protected mode the range is the entire 4G-byte address space. The MOD field specifies the addressing mode for the selected instruction.
