Question
Define ICT.
Answer
**Information and communications technology** — the hardware, networks and software that move information (internet, phones, satellites, data centres).
Question
What is time-space convergence?
Answer
As ICT improves, the **friction of distance shrinks**, so distant places feel closer in time and cost even though real distance is unchanged.
Question
Define data flow.
Answer
The **movement of digital information** (messages, money, media, files) across networks between places.
Question
What is the digital divide?
Answer
The **uneven access to ICT** between rich and poor countries, and between people within them — some are far better connected than others.
Question
What is the cloud?
Answer
Remote **data centres** that store and process information over the internet, so a file or service can be reached from anywhere.
Question
Which flows have largely moved online?
Answer
**Data and information**, **finance** and **communication** — they have little physical form, so they cross borders as data in seconds.
Question
Which flows must stay physical?
Answer
**Energy, food and raw materials** — oil, grain and iron ore must be piped, shipped or trucked; they cannot be digitised.
Question
How do digital and physical flows connect?
Answer
Digital networks usually **coordinate** physical flows (plan, price and track shipments) rather than replacing them.
Question
Name four illicit global flows.
Answer
**Trafficking** of people, **counterfeit** goods, **narcotics** and **hidden (laundered) money**.
Question
Why is data on illegal flows unreliable?
Answer
The flows are **deliberately hidden**, counting methods differ and seizures capture only a fraction — so any figure is a rough estimate.
Question
Why does that unreliable data still matter?
Answer
Illicit flows shape real places (crime, exploitation, lost revenue), so governments need **rough estimates** to govern them — what is unmeasured goes ungoverned.
Question
How do you structure a To-what-extent essay?
Answer
**FOR** the claim, then **AGAINST** the claim, then a **JUDGEMENT** that answers how far the claim holds — never a fence-sit.
