H2O Networks

H2O Networks 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 H2O Networks rather than just read about it. In short: H2O Networks, sometimes called the Water Networks, was a British telecommunications company founded in 2003 by Elfed Thomas. It was supposed to be rolling out Fibrecity around the UK.

Key takeaways

H2O Networks 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 H2O Networks to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of H2O Networks from memory before moving on to harder problems.

Reference excerpt

H2O Networks, sometimes called the Water Networks, was a British telecommunications company founded in 2003 by Elfed Thomas. It was supposed to be rolling out Fibrecity around the UK. They were formally part of the i3 Group. H2O Networks in their Fibrecity (Bournemouth) and Fibrecity (Dundee) guises ceased their builds in October 2010 stating that there would be a short delay due to company restructuring. Their installation contractors in both cities were laid off. In January 2011 it was announced that there had been a management buy-out of the H2O Networks part of the i3 business, including Fibrecity, by the ex i3 Group CCO Greg Mesch, the new company is to be called City Fibre Holdings. Revelations about the financial backing behind H2O Networks were released in February 2011. H2O was one of ten companies used by Stephen Dartnell and his co-conspirators to fraudulently obtain over £250m, with H2O the biggest victim, with an amount of over £160m. Total Asset Finance, the backers, were subject to an investigation by the Serious Fraud Office and, allegedly owed a Belgian bank over £130 million. Over £90 Million of this is apparently related to loans being used to finance H2O Networks. Four individuals were convicted in 2017 of conspiracy to commit fraud, and two acquitted. The crown court case started in September 2016, with the final sentencing handed down in February 2017. George Alexander and Stephen Dartnell, of Total Asset Limited, were sentenced to 12 and 15 years respectively at Southwark Crown Court. Simon Mundy, who worked for KBC Lease was sentenced to 7 years. Carl Cumiskey of H2O Networks Limited was sentenced to 10 year's imprisonment. Elfed Thomas was found not guilty and exonerated from all charges. In January 2018, Elfed Thomas announced the launch of his first business venture since the court case, British Fibre Networks, which aims to build pure fibre connections to more than 35% of new homes by 2021.

Worked examples

Example 1 — a first encounter with H2O Networks

Start with the simplest possible case. Write down what H2O Networks 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 H2O Networks 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 H2O Networks 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 H2O Networks

In research: H2O Networks 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 H2O Networks 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: H2O Networks is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telecommunications in the United Kingdom, United Kingdom company stubs, so understanding it makes those chapters shorter.
In everyday life: Look for H2O Networks 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 H2O Networks in simple terms?

H2O Networks, sometimes called the Water Networks, was a British telecommunications company founded in 2003 by Elfed Thomas. It was supposed to be rolling out Fibrecity around the UK.

Why does H2O Networks 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 H2O Networks?

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.
