ITerating

ITerating 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 ITerating rather than just read about it. In short: ITerating was a Wiki-based software guide, where users could find, compare and give reviews to software products. As of January 2021 the domain is listed as being for sale and the website no longer on-line.

Key takeaways

ITerating 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 ITerating to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of ITerating from memory before moving on to harder problems.

Reference excerpt

ITerating was a Wiki-based software guide, where users could find, compare and give reviews to software products. As of January 2021 the domain is listed as being for sale and the website no longer on-line. Founded in October 2005, and based in New York, ITerating was created by CEO Nicolas Vandenberghe, who saw that there was an industry need for a comprehensive resource to help evaluate software solutions. The site aims to be a reference guide for the IT industry and includes reviews, ratings, articles, and detailed product feature comparisons. ITerating uses Semantic Web tools (including RDF - Resource Description Framework) to combine user edits with Web service feeds from other sites. Designed for use by developers and industry consultants, ITerating allows users to contribute to categories such as Software Engineering Tools; Website Design & Tools; Website Software Tools; Website & Communication Applications & Social Networking; or to create their own category if does not exist yet.

Wiki Matrix Iterating announced the addition of a Feature Matrix in June 2007, which allows users to dynamically create customized, side-by-side feature comparisons of software solutions.

Worked examples

Example 1 — a first encounter with ITerating

Start with the simplest possible case. Write down what ITerating 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 ITerating 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 ITerating 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 ITerating

In research: ITerating 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 ITerating 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: ITerating is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computing websites, Defunct software companies of the United States, Online databases, so understanding it makes those chapters shorter.
In everyday life: Look for ITerating 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.

Frequently asked questions

What is ITerating in simple terms?

Why does ITerating matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study ITerating?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on ITerating.
