Computing & Technology quizzes
Computers, internet, programming
Computing & Technology brings together everything behind our connected world: hardware such as processors, memory and storage, operating systems, networks and the web, programming languages, algorithms, cybersecurity, and the people who shaped the field, from Alan Turing and Ada Lovelace to Tim Berners-Lee. Expect bits and bytes, cloud services, artificial intelligence, search engines and social networks.
This theme suits curious beginners as much as people who already code, since you can test your computing knowledge at your own pace. The quizzes are free, played on five levels from very easy to expert, and each answer comes with a short explanation that clarifies the concept.

Frequently asked questions about Computing & Technology
What is the difference between a bit and a byte?
A bit is the smallest unit of information in computing and has a value of 0 or 1. A byte groups 8 bits and can take 256 different values, from 0 to 255. It is the basic unit used to measure file sizes, in kilobytes, megabytes and gigabytes.
What is the difference between the internet and the web?
The internet is the worldwide network linking millions of smaller computer networks. The web is one service running on top of it: a collection of pages connected by hyperlinks and viewed in a browser. It was conceived by Tim Berners-Lee at CERN in the late 1980s. Email is another service that uses the internet.
What is an algorithm?
An algorithm is a finite, ordered list of precise instructions for solving a problem or completing a task, much like a recipe. Written in a programming language, it becomes a program that a computer can run. The word comes from the name of the ninth-century mathematician al-Khwarizmi.
