Inventions, engineering, the internet and the machines we built.
Technology quizzes date badly, so these concentrate on the parts that do not: how something works, why it was invented, and what problem it was solving.
The section covers inventions and engineering, the internet and how it is actually held together, robotics and artificial intelligence, and general technology from ancient tools to current hardware. A question about a protocol or a bridge or a printing press is really a question about a constraint someone had to design around, and that is what the explanations focus on.
This is one of the smaller sections and it grows as new quizzes are written.
The devices that changed what was possible.
Machines that act, and systems that learn.
From ancient tools to the machines that run today.
The network everyone uses and few can describe.
Containers, barcodes, lift brakes and drain traps — modest devices with outsized effects.
The standard shipping container mattered chiefly because it did what?
Steel, rubber, glass and silicon — the substances that set the limits of what could be built.
The Bessemer process, introduced in the 1850s, made which material cheap for the first time?
Packets, CERN, HTML and the browser that turned a physics tool into a mass medium.
Packet switching, the idea underneath the internet, works by doing what?
Phishing, second factors, ransomware and why length beats punctuation in a password.
Phishing is best described as what?
Two centuries of arguments about whether a machine could think, and what happened when people tried.
Who is usually credited with publishing the first algorithm intended to be carried out by a…
Actuators, end effectors and the awkward business of staying upright.
In robotics, an actuator is the part that does what?
Telegraph, radio, television and satellites — how messages travelled first.
The electric telegraph transmitted messages using what?
Processors, memory, storage and what each part actually does.
What does the CPU do?
