- Define the nearest segment number (the largest possible segment number with the least offset) for the following addresses.
- For each address, specify the logical addresses (Segment_number:Offset) for each possible segment.
- Your answer should give the addresses in increasing order from the least segment number to the largest segment number.
- Each value, segment number or offset, must contain 4 hexadecimal digits.
- For multiple addresses, separate the addresses by semi-colons. Use the following syntax (0213:0003);(0213:0100);(0512:0130)
- All values are hexadecimal values you don't have to specify the H.
- Do not include any spaces.
