19 of the Digital Society glossary’s terms, each with the part of the syllabus where you first meet it.
Data in which each example is tagged with the correct answer, such as an email marked spam or not spam, used to train supervised learning systems.
A deep learning model with billions of weights, trained on vast amounts of text to predict the next token in a sequence, which allows it to generate fluent text and perform many language tasks.
The time delay between data being sent and being received across a network, usually measured in milliseconds.
When a country or community skips a stage of technological development and moves directly to a newer technology, such as adopting mobile phones without first building a network of fixed telephone lines.
Software that schools and organisations use to deliver, organise and track courses, including resources, assignments, communication and grades.
A weapon that, once activated, can select and attack targets, including people, without further human intervention.
A six-level scale from 0 to 5, set out by SAE International, that describes how much of the driving task a vehicle's automated system performs, from no automation to full automation under all conditions.
A sensing method that fires pulses of laser light and measures how long they take to bounce back, building a precise three-dimensional map of nearby objects and their distances.
A method for measuring the environmental impacts of a product or service across every stage of its life, from extracting raw materials through manufacturing, transport and use to disposal or recycling.
Excessive or badly directed artificial light, such as skyglow over cities, glare and light spilling into places where it is not wanted, which disrupts ecosystems, human sleep and views of the night sky.
Content presented in a fixed order and, for broadcasts, at a fixed time chosen by its creator, so every audience member follows the same sequence.
A searching algorithm that checks each item in a list in turn, from the start, until it finds the target or reaches the end; it works on unsorted lists but is slow for large ones.
Broadcasting video and audio over the internet as events happen, so viewers can watch in real time and often interact through live chat.
Attempts by organised groups, such as companies, trade associations, unions and campaign groups, to influence the decisions of lawmakers and officials through direct contact, research, events and public campaigns.
A network that connects devices within one building or site, such as a home, school or office, usually owned and managed by one organisation.
The painful feeling that one's social relationships are fewer or less satisfying than one wants, which can occur even when a person is surrounded by others; it differs from social isolation, an objective lack of contact.
A component of an algorithm that repeats a block of instructions, either for each item in a collection, a set number of times, or while a condition remains true.
Data compression that allows the original data to be rebuilt exactly, used for text, software and files where every detail matters.
Data compression that permanently discards some data, usually detail people barely notice, to make files much smaller, used for photos, music and video.
