Software that performs a sequence of routine steps that people previously did by hand — moving data between systems, sending notifications, creating records, routing approvals — and it fails in
An application holding verifiable credentials — cryptographically signed statements about you issued by a trusted body — that you present selectively, without the verifier needing to contact the
Technology used for work without the knowledge or approval of the organisation's IT function — personal cloud storage, unapproved apps, a departmental subscription paid on a card, a spreadsheet
A live virtual model of a physical thing, kept synchronised with it by a continuous stream of sensor data — which is what distinguishes it from an ordinary simulation or a 3D model. The three
In most jurisdictions yes, for the great majority of documents — the law generally does not require a handwritten signature, and the practical question is evidential: can you prove who signed, that
An embedding turns a piece of content — text, an image, audio — into a list of numbers positioned so that similar things land near each other. A vector database stores those lists and finds the
As a two-dimensional pattern of black and white squares read as binary, with substantial built-in error correction — which is why a code still scans when damaged, partially covered or printed over a
Through three separate processes that people conflate: crawling, indexing and ranking — and a page can succeed at the first two and still never appear, which is the source of most confusion about why
By locating text in an image and then recognising it — two separate problems, and the second is far easier than the first, which is why scanning a clean document works well and photographing a sign
By converting sound into a numerical representation, then using a model trained on enormous quantities of speech to produce the most probable sequence of words — and "most probable" is the key,
Spatial computing means interfaces that operate in three-dimensional space around you rather than on a flat screen — headsets, passthrough mixed reality, hand and eye tracking. The technology works
The future cost of a shortcut taken now — the extra work created when code is written to be delivered rather than to be maintained. The metaphor is deliberate: like financial debt, it can be a
Far less automatically than people assume. Most accounts are licences to use a service, not property, and access is governed by the provider's terms rather than by your will — which is why planning
Processing data near where it is produced rather than sending it to a distant data centre — a response to the fact that some problems are not solved by more bandwidth, because the constraint is
A mathematical guarantee that the output of an analysis reveals almost nothing about any single individual in the data — achieved by adding carefully calibrated random noise, and notable for being
By converting a face into a numerical vector and comparing distances between vectors — not by matching pictures, which is the misconception underlying most public discussion of it. The pipeline:
Through near-field communication, a short-range radio standard where the terminal powers the card and exchanges a few messages — and the security model is considerably stronger than the convenience
Your device does not transmit anything. It listens to signals from satellites and works out its own position from the tiny differences in how long each signal took to arrive — which makes it a
A fundamentally different model of computation using qubits rather than bits — and its realistic near-term applications are far narrower than the coverage suggests. It is not a faster computer; it is
By using two mathematically related keys where one encrypts and only the other decrypts — which solves the problem that had blocked secure communication for centuries: how to agree a secret with
A core is a physical processing unit; a thread is a stream of instructions a core executes; a GPU is a fundamentally different processor designed for a different shape of problem. Confusing them
That people with disabilities can perceive, operate, understand and use a digital service — and the practical standard almost everywhere is WCAG, whose four principles are exactly those four words.
A vulnerability scan is automated and tells you what might be exploitable; a penetration test is human-led and demonstrates what actually is, by exploiting it. They cost, take and tell you completely
A structured process rather than improvisation — and the organisations that handle incidents well are almost always the ones that decided what to do before anything happened, because the middle of a
