The Icon Bar

The Icon Bar is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The Icon Bar rather than just read about it. In short: The Icon Bar (also referred to as TIB) is a computing and technology website with a focus on the RISC OS computer operating system. History The Icon Bar was founded in 2000 by Tim Fountain, Alasdair Bailey and Richard Goodwin.

Key takeaways

The Icon Bar belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect The Icon Bar to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of The Icon Bar from memory before moving on to harder problems.

Reference excerpt

The Icon Bar (also referred to as TIB) is a computing and technology website with a focus on the RISC OS computer operating system.

History The Icon Bar was founded in 2000 by Tim Fountain, Alasdair Bailey and Richard Goodwin. In 2004, co-founder Richard Goodwin was nominated for the Drobe awards for keeping the "popular forum" online. It was further developed by the same people who developed Acorn Arcade, the contents of which were incorporated in 2006. At this time, it broadened its remit to also cover alternative platforms and new technologies, while still keeping abreast of the RISC OS scene. When Drobe closed as a news site in 2009, The Icon Bar was cited as a notable alternative and took over running the annual awards scheme for the RISC OS scene. It has been selected for inclusion by editors in at least one web directory,

Content The site features RISC OS articles, news, forums and other media. It also hosts a Media Watch page, where users can share any relevant items they spot in the media.

Worked examples

Example 1 — a first encounter with The Icon Bar

Start with the simplest possible case. Write down what The Icon Bar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The Icon Bar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The Icon Bar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The Icon Bar

In research: The Icon Bar appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses The Icon Bar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: The Icon Bar is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computing stubs, Computing websites, History of computing, so understanding it makes those chapters shorter.
In everyday life: Look for The Icon Bar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
