13.[ 3] The two unsigned numbers are subtracted, th e Subtrahend is less than the subtractor, ther e is a borrow, the result is negative, and ther esult obtained at this time is (A The original code 1's Complement (C) 2's Complement Absolute value 14.[ 3] When two signed numbers calculations result in overflow, it indicates that the result is Original code B 1's Complement 2's Complement 12.[ 3] It is known that the storage data of a 32- bit computer system uses little- endian, and the storage unit starting from ad dress Ox2000 stores the data below. what is the corresponding decimal value of 32 bits integer at address Ox2000? Address 0x2000 Ox2001 0x2002 0x2003 Value 2 3 6 0 393986 15. [9 ] Floating point arithmetic process produces ov erflow, which means When the result is normalized, the p ositive index value exceeds the maxi mum value that the index may repre sent. When the results are normalized, th e negative index value exceeds the minimum value that the index mayr epresent When the result is normalized, the m antissa exceeds the maximum value that the mantissa can represent When the result is normalized, the m antissa exceeds the minimum value that the mantissa can represent E 16.3 Among the data represented by the two's complement below, whose true value is -8 A OXF8 OxFFF8 C0xFFFFFFF8 D0x88 17.
