Question

The hexadecimal dump from part of a big-endian computer’s memory is as follows (5 each)

1200) 434F 4D50 5554 5245

1208) FFF2 3508 0100 57FC

1210) 7892 4123 0000 1234

Decode the hexadecimal data, assuming that it is a sequence of:

• 8 ASCI encoded characters – write the characters;

• one 2’s complement 16-bit number – present the decimal number;

• IEEE Floating point single precision number –present the binary scientific notation of the number;

• one byte binary number in octal system - present the octal number;

• one 8-bit number presented in Excess 127 code - present the decimal number

• 4 bytes natural BCD number – present the encoded decimal number

• Special IEEE Floating point number – present the binary scientific notation

8 bit ascii
