What a finished IT 105 Unit 2 data representation paper looks like
The paper alternates between short explanations and small worked demonstrations. It opens by declaring the widths under discussion and deriving what each one can hold, showing the arithmetic instead of citing a table. Signed representation follows, with the chosen scheme explained by the problem it solves for the hardware that has to add, and with the same value shown in both its unsigned and its signed reading so the difference is visible rather than asserted. An overflow demonstration comes next: two values within range, an operation, and a result that is not, with the wrap traced digit by digit. The section on fractional values separates the range a format offers from the precision it keeps, and closes on an accumulation example where a repeated operation drifts. Every figure belongs to the paper's own stated widths.
How a IT 105 Unit 2 example is structured
Width is declared before anything else because every subsequent claim is conditional on it, and a paper asserting that a number is too large without saying too large for what has said nothing. Ranges are derived rather than quoted so the reader can follow the count instead of trusting a memorized pair of limits, which also protects the paper when the width changes. The signed scheme is introduced through the hardware problem it answers, since presenting it as a convention leaves the design reasoning this course grades entirely out. Overflow is demonstrated before it is described, as the wrap is obvious once watched and abstract when explained. Precision is separated from range in its own section because the two get conflated in almost every draft. The accumulation example comes last, being the consequence that matters most and the one least often reached.
Width declared before any claim
The paper says how many bits it assumes, since a statement about what a value can hold means nothing without that number.
Ranges derived rather than quoted
Limits are counted out on the page instead of recited, which keeps the reasoning visible and survives a change of width.
The signed scheme justified by hardware
Representation is introduced through the problem it solves for circuitry that has to add, rather than as an arbitrary convention.
Overflow watched, then explained
A worked operation carries two in-range values past the boundary and traces the wrap before any prose describes what happened.
Range and precision kept apart
How far a format reaches and how finely it divides are treated as separate properties, because conflating them produces most of the confusion here.
Accumulated drift demonstrated at the close
A repeated operation shows small representation error compounding, which is the consequence that matters and the one drafts rarely reach.
Where marks go in IT 105 Unit 2
Papers lose marks by describing a representation without ever deriving anything from it. A correct account of how negative values are encoded, with no range counted and no operation worked, demonstrates reading rather than understanding. Claims that a value is out of range, with no width stated anywhere nearby, cannot be evaluated. Treating overflow and rounding as one phenomenon confuses a boundary problem with a precision problem, and the two have different remedies. Fractional formats presented as simply inaccurate miss the trade the design is making. Worked demonstrations with arithmetic slips undermine everything around them. Asserting that a particular language or machine uses a particular width, as a general fact, states something that varies and dates the paper.

IT 105 Unit 2 questions, answered
Can I use data from a system I work on?
There is no need and a real cost. Representation questions are answered entirely with values you invent, so an extract from an employer's system adds nothing to the argument while carrying that organization's records into a graded file. Choose your own small values, state the width they are being read at, and the demonstration is both cleaner and free of anything you would have to explain later.
Do I need to name a specific processor or language?
Better not to, beyond an illustration clearly labeled as one. Widths and formats vary between implementations and change over time, so a paper that pins its reasoning to a named product inherits a fact it cannot verify and a marker cannot check. Stating the width you assume keeps every derivation valid regardless of what any particular machine happens to do.
How much arithmetic should the paper contain?
Enough that each claim has one demonstration under it, which usually means three or four small worked cases rather than a page of them. The criterion is that the reader can see the representation behaving, not that the paper is exhaustive. Where the instructions supply problems, work those and keep any extra example short enough to read in a glance.
