IELTS vocabulary: Technology

Technology is arguably the topic where candidates lose the most marks to vagueness, because the word itself is so broad that almost any sentence containing it is technically true and therefore says almost nothing. "Technology is changing our lives" could open an essay about smartphones, AI, biotechnology, or agricultural machinery, and an examiner reading that sentence has no idea yet what the essay is actually about. The fix isn't a longer vocabulary list in the abstract sense — it's naming which technology, what kind of change, and for whom, using terms precise enough that the sentence would be false if a different technology were substituted in. This article works through that vocabulary in the groupings an actual essay needs: the process of change itself, adoption and access, benefits, risks, and the confusions that undercut otherwise strong answers.

Start with vocabulary for the process of change, since most essays skip straight to effects without naming the mechanism producing them. "Automation" is the replacement of human labour with machines or software for a specific task — distinct from "artificial intelligence," which refers to systems that perform tasks requiring judgement, pattern recognition, or decision-making rather than simply repeating a fixed physical action. "Digitisation" is the narrow, technical process of converting analogue information (paper records, physical photographs, printed forms) into digital format; "digitalisation" is the broader organisational shift toward digital processes and business models built around that converted data — the two terms are frequently used interchangeably by candidates, which is itself worth avoiding. "Technological disruption" names the effect of a new technology displacing an established industry or practice, as with ride-sharing apps disrupting the traditional taxi industry. "Technological determinism" is a more advanced term worth knowing passively even if rarely used actively: the view that technology itself drives social change, rather than being shaped by the societies that adopt it — useful for a sophisticated Task 2 thesis that pushes back against a prompt's assumption that technology alone "causes" a given outcome.

Vocabulary for adoption and access splits candidates who write generically about "technology" from those who can locate a specific claim. "Early adopters" are the first, typically smaller group willing to use a new technology before it's widely trusted or affordable. "Digital literacy" is the practical ability to use digital tools and evaluate digital information competently — distinct from "digital divide," which names the structural gap in access to reliable technology and connectivity between different groups, whether by income, age, or geography. "Interoperability" (the ability of different systems or devices to work together smoothly) is a genuinely underused but precise term for essays about why a promising technology fails to scale in practice. "Legacy systems" refers to older technology still in use, often because replacing it is expensive or disruptive — a useful phrase for essays about why institutions like hospitals or governments adopt new technology more slowly than consumers do.
