Short answer: Technology questions appear constantly across IELTS Writing Task 2 and Speaking, so mastering precise words such as innovation, automation, ubiquitous and disruptive is one of the quickest routes to a higher Lexical Resource score.
The 30 words below include meanings, natural collocations and example sentences ready to use in an essay or a Speaking response.
Technology threads through dozens of IELTS prompts: social media, automation and jobs, online education, privacy and surveillance, and the effect of smartphones on daily life.
The vocabulary is highly reusable — the same 30 words serve an essay on artificial intelligence and a Speaking Part 3 answer about how the internet has changed your country.
A writer who reaches for obsolete, streamline and connectivity instead of "old", "make faster" and "internet" signals a higher band at once. Here are 30 genuine Band 7+ technology words, each with the collocation that makes it usable and an example sentence in context.
Why topic vocabulary lifts your Lexical Resource band
Lexical Resource is one of four marking criteria in Writing and Speaking, each equally weighted — so vocabulary carries a full quarter of your mark on those papers.
The public descriptors state that Band 7 needs "a sufficient range of vocabulary to allow some flexibility and precision" and use of "less common lexical items… with some awareness of style and collocation" (see the official IELTS Writing Task 2 band descriptors).
Because technology is so predictable a theme, preparing this language in advance is one of the highest-return things you can do before test day.
The standard is accurate use, though, not difficulty for its own sake. A less common word dropped into the wrong collocation ("do a technology", "a big innovation of jobs") reads as reach without control and can pull your band down.
That is why every entry below is paired with its natural partners — the collocation is the thing to learn. For a structured month that builds active vocabulary across topics, follow our IELTS vocabulary 30-day plan.

How to use these words in Writing and Speaking
Learn each word inside its collocation rather than alone. "Streamline" on its own is fragile; "streamline the process" is a ready-made, low-risk phrase. The collocation column is the part worth memorising — those partnerships are what stop a good word from being used wrongly.
A quick test before you commit a word to an answer is whether you can produce it in a full phrase without hesitating; if the collocation does not come to mind, the word is not yet ready for the exam, and a plainer choice will serve your accuracy better.
Half a dozen words you own completely will lift your band further than thirty you only recognise.
It also helps to group the words by the job they do — describing benefits (streamline, enhance, facilitate), risks (surveillance, addictive, redundant) and change (disruptive, revolutionise, obsolete) — so the right cluster comes to mind the moment a prompt names its angle.
Then use the words sparingly and where they fit. One or two precise items per paragraph, correctly placed, out-score a paragraph crammed with impressive nouns you cannot control — the descriptors reward accuracy, and a single wrong collocation is more visible to an examiner than several plain sentences.
The reliable way to make a word active is daily use: the IELTSbiz Word Coach gives you a word a day with practice, which is how vocabulary crosses from "I recognise it" to "I can produce it under pressure".
Remember that both UK and US spellings are accepted, so "digitalise" and "digitalize" are equally fine — just stay consistent within an answer.
A worked example: technology vocabulary in a Task 2 paragraph
The prompt and paragraph below were written for this article as a teaching example, not taken from any real exam. The prompt idea: "Some people think automation and artificial intelligence will do more harm than good to the workforce. To what extent do you agree?"
"There is no doubt that automation will make some roles redundant, particularly the repetitive clerical work that software can now streamline at a fraction of the cost. Yet the same disruptive technologies that eliminate old jobs also create new ones, from maintaining the algorithms themselves to fields that did not exist a decade ago. The greater risk is not unemployment but inequality: workers with strong digital literacy will enhance their prospects, while those without it may be left behind as these tools become ubiquitous."
Only eight higher-level words appear across three sentences, each in a natural collocation, and the paragraph still reads as argument rather than a vocabulary display. That ratio — precise where it earns marks, plain everywhere else — is the goal.

Where to practise technology vocabulary in context
Vocabulary sticks fastest when you meet it inside genuine reading rather than on a list. Our technology reading practice generates Cambridge-style passages on this theme, so you see words such as innovation, surveillance and connectivity working in real academic sentences and the collocations become intuitive.
From there, drill by question type with per-type practice and trap-level feedback, which pinpoints where a misread word cost you a mark. Topic reading plus targeted practice is what converts a word list into vocabulary you can produce on test day.
Common technology vocabulary mistakes to avoid
The commonest slip is word-form confusion. Innovate is the verb, innovation the noun and innovative the adjective, so "a very innovation company" should read "a very innovative company".
The same care applies to rely, reliance and reliable, and to depend, dependence and dependent — mixing them is one of the fastest ways to signal a lower band.
Learn the whole family together so the right form comes automatically under time pressure rather than after a pause you cannot afford.
The second problem is collocation. Technology is adopted, developed or rolled out, not "made" or "done"; a device is obsolete or outdated, not "expired"; and you keep up with technology rather than "follow" it.
Countability matters too, because technology, software and hardware are usually uncountable, so "a software" and "many technologies" in the general sense read as errors — say "a piece of software" or "many technological changes" instead.
When in doubt, choose a plain phrase you control over an impressive one you do not, because the descriptors weigh accuracy above ambition. Reading these words in genuine passages, not on a list, is what fixes the partnerships in memory.
Conclusion
Technology is a theme you can prepare for with confidence because it recurs so often and its vocabulary transfers across dozens of prompts.
Thirty precise words — learned in their collocations, used where they are natural, and met again in real reading — cover most of what Writing Task 2 and Speaking will ask on this topic.
Build them into active vocabulary through daily practice and topic reading, keep accuracy ahead of ambition, and your Lexical Resource band will rise with it.
