CSC303 Data Representation - Tutorial Sheet, 2021/2022 - University of
- First semester 2021/2022 academic year tutorial sheet on Data Representation, University of Buea, Faculty of Science, Dept of Computer Science: a digital/typed source (not a scanned exam) with no marks allocation.
- Decimal/binary/hexadecimal conversions (including a fractional-decimal-to-binary conversion flagged as a non-terminating binary expansion, truncated and noted as an approximation); 8/16/32/64-bit unsigned and 2's-complement signed integer ranges, with worked 8-bit unsigned, 2's-complement, sign-magnitude and 1's-complement representations of a shared value set; 32-bit IEEE-754 normalized and denormalized largest/smallest positive/negative value computations; and a final two-code interpretation exercise (16-bit unsigned/signed, pairs of 8-bit unsigned/signed, a 16-bit Unicode code point, and two 8-bit ISO-8859-1 bytes), with the Unicode glyph and the ISO-8859-1-vs-Windows-1252 byte-0x80 ambiguity both explicitly flagged rather than asserted.
