1. 1

   How does the law treat digital piracy, and what does the evidence say about the harm it causes?

   Model answer

   Legally, downloading or streaming an infringing copy engages the copyright owner's exclusive rights and is civil infringement; uploading or sharing is additionally distribution or communication to the public and is treated more seriously, with criminal offences available for commercial-scale activity or distribution that prejudicially affects the owner, carrying up to ten years. Enforcement in the United Kingdom has shifted from suing individuals, which proved unpopular and produced poor publicity, to court orders requiring internet service providers to block access to sites dedicated to infringement, and to prosecuting operators of such sites. The notification provisions of the Digital Economy Act 2010, which would have required warning letters and possible technical measures against subscribers, were never put into effect, because the code of practice they depended on was never made. On harm the evidence is genuinely contested. Industry bodies publish loss figures calculated by treating infringing copies as lost sales. Academic work generally finds displacement well below one to one, because many people who take a free copy would not have paid; Oberholzer-Gee and Strumpf found effects on music sales statistically indistinguishable from zero, and a study commissioned by the European Commission and published in 2017 found little robust evidence of displacement across most content types, with recent blockbuster films the clearest exception. A separate strand of evidence is that piracy of music and television fell substantially where convenient, affordable legal streaming became available, which supports the view that much infringement is a response to price and availability rather than to a preference for stealing. None of this makes infringement lawful; it bears on what proportionate enforcement looks like.

2. 2

   What laws in the United Kingdom deal with offensive or threatening online communications, and where is the line drawn?

   Model answer

   Several overlapping provisions. Sending a message that is grossly offensive, or of an indecent, obscene or menacing character, by means of a public electronic communications network is an offence under the Communications Act 2003. Sending a letter or electronic communication that is indecent, grossly offensive, threatening or contains false information, with the purpose of causing distress or anxiety, was an offence under the Malicious Communications Act 1988. Repeated conduct causing alarm or distress can amount to harassment or stalking under the Protection from Harassment Act 1997. Disclosing a private sexual photograph or film without consent and with intent to cause distress was made an offence by the Criminal Justice and Courts Act 2015. The Online Safety Act 2023 added new false communications and threatening communications offences and repealed some of the older provisions. On where the line falls, the leading case is the 2012 appeal in which a man convicted for a plainly frustrated joke about blowing up an airport was cleared, the High Court holding that a message must be a genuine menace rather than merely in poor taste and that context and the likely audience matter. The Director of Public Prosecutions subsequently issued guidelines setting a high threshold for prosecuting communications that are merely offensive, on the basis that the criminal law should not be used to police rudeness. The persistent difficulty is that grossly offensive has no fixed meaning and depends on contemporary standards, which is precisely the objection free expression campaigners make.

3. 3

   Would requiring real names online reduce abuse? Give the arguments and the evidence.

   Model answer

   The case for: anonymity lowers the perceived cost of cruelty because there is no reputational consequence, it obstructs investigation, and it enables sockpuppeting and coordinated harassment by a small number of people appearing to be many. The case against: anonymity and pseudonymity protect domestic abuse survivors, whistleblowers, LGBT people in hostile settings, people with stigmatised health conditions, and political dissidents, so removing it silences exactly the users with most to lose; real-name policies require identity verification, creating a database of identities that becomes a target; and a good deal of abuse is committed by people using their real names, which suggests disinhibition is not principally about concealment. On evidence, South Korea introduced a real-name requirement for large sites in 2007; the Constitutional Court struck it down in 2012, and empirical study of the period, including work by Cho and colleagues, found only a small reduction in uncivil comments alongside a fall in participation. Platform experiments have produced similarly modest effects. The middle position increasingly taken is to keep pseudonymity for display while improving traceability through legal process, and to give users tools to filter unverified accounts, which shifts the choice to the recipient rather than banning anonymity outright.

4. 4

   Why does the layout of a screen matter beyond looking tidy?

   Model answer

   Because layout determines who can use the thing at all. Several distinct groups depend on it. Screen reader users navigate by structure, so headings must be real headings marked up in order rather than large bold text, tables must have proper header cells, and a skip link must let them bypass repeated navigation; a page that looks organised but has no underlying structure is unusable to them. Keyboard-only users, including people with motor impairments and many screen reader users, depend on the focus order following the visual order and on the focused element being visibly indicated, so a layout positioned with CSS in a different order from the underlying markup strands them. People with low vision need the page to reflow when magnified: the Web Content Accessibility Guidelines require content to be presentable at a width equivalent to three hundred and twenty pixels without two-dimensional scrolling, which rules out fixed-width layouts. People with motor tremor need targets large enough and far enough apart to hit, with the guidelines setting a minimum target size. People with attention or cognitive differences benefit from consistent placement of navigation, short line lengths, generous spacing, and no unexpected movement. And everyone benefits from a clear visual hierarchy, since reading on screen is largely scanning: size, weight, position and whitespace are what tell a reader what matters, and a page where everything is emphasised communicates no priority at all.

5. 5

   What does a designer have to change when the same interface has to work in another language and another country?

   Model answer

   Text direction: Arabic, Hebrew, Farsi and Urdu read right to left, and the whole layout normally mirrors with them, so navigation, icons implying direction, progress bars and sliders all flip. Text expansion: translation changes length, and German, Finnish and Russian commonly run substantially longer than English while Chinese and Japanese run shorter, so fixed-width buttons and labels break; the standard remedy is to design containers that grow and to test with pseudo-localised strings. Formats: dates differ in order, the separators for thousands and decimals swap between locales, currency symbols sit before or after the amount, address fields differ in name and number, personal names do not divide reliably into a first and last name, and telephone and postal code validation must not assume one country's pattern. Sorting: alphabetical order is locale-dependent, so a correct sort needs a locale-aware collation rather than comparison of code points. Time: time zones, daylight saving and non-Gregorian calendars. Typography: line breaking rules differ, Chinese, Japanese and Thai do not put spaces between words, and some scripts need much greater line height. Content: icons and imagery carry cultural meaning, a hand gesture that is friendly in one country is obscene in another, and examples using local sports or holidays do not travel. The engineering principle behind all of it is to separate translatable strings and locale rules from code so that adding a locale is data rather than a rewrite.

6. 6

   Explain what a colour model is and why more than one is needed.

   Model answer

   A colour model is a scheme for describing a colour numerically. RGB is additive: red, green and blue light are combined, so all three at full intensity give white and all at zero give black. It matches how emissive displays work, since a pixel is made of red, green and blue subpixels, and it is what is used on screen, typically at eight bits per channel giving two hundred and fifty-six levels each and about sixteen point seven million combinations. CMYK is subtractive: cyan, magenta, yellow and black inks absorb light from white paper, so more ink means darker. It is used for print because print reflects light rather than emitting it, and the fourth black channel exists because mixing the three coloured inks produces a muddy dark brown rather than a true black and uses three times the ink. HSL and HSV describe a colour by hue, saturation and lightness or value, which maps far better onto how people think about colour, which is why colour pickers and design tools use them and why generating a consistent palette is easier in HSL than in RGB. The practical consequence of having several models is gamut: each device can reproduce only a subset of visible colours, and the printable CMYK gamut is smaller than a typical screen's, so a vivid on-screen colour may print noticeably duller. This is why colour management profiles exist and why designers proof print work rather than trusting the monitor.
