SoftBank Telecom is a 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 SoftBank Telecom rather than just read about it. In short: SoftBank Telecom Corporation (Japanese: ソフトバンクテレコム株式会社, Hepburn: Sofuto Banku Terekomu Kabushiki-gaisha) was a Japanese telephone company and part of the SoftBank group. It provided services to both businesses and consumers in Japan, including long-distance telephone service, international calling, and direct connection fixed-line voice service.

Learn the definition first, then one example that makes the definition concrete.
Connect SoftBank Telecom to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SoftBank Telecom from memory before moving on to harder problems.

Reference excerpt

SoftBank Telecom Corporation (Japanese: ソフトバンクテレコム株式会社, Hepburn: Sofuto Banku Terekomu Kabushiki-gaisha) was a Japanese telephone company and part of the SoftBank group. It provided services to both businesses and consumers in Japan, including long-distance telephone service, international calling, and direct connection fixed-line voice service. The company also engaged in billing and fee collection for telephony services, consulting, development and establishment of telecommunication systems, as well as information processing and related services. On 1 April 2015, SoftBank Telecom Corporation merged into SoftBank Mobile Corporation and ceased to exist as a separate entity. The company's history traces back to October 1984, when Japanese Telecom Telegraph was founded. In August 1986, it launched leased circuit services. In December 1986, as the Japanese government prepared to divide and privatize the Japanese National Railways (JNR), it established a Railway Telecommunication company (JR Telecom) to take over telecommunications related systems owned by JNR. Following the division and privatization of JNR on 1 April 1987, the company commenced operations. In May 1989, Japanese Telecom Telegraph merged with JR Telecom. In August 2002, the company changed its name to Japan Telecom Holdings, separating its fixed-line telecommunications business to form a new Japan Telecom. The company was renamed SoftBank Telecom Corporation in October 2006. Following its merger into SoftBank Mobile Corporation in April 2015, the company effectively ceased operations under the SoftBank Telecom name. In December 2018, the company went public through an initial public offering.

Worked examples

Example 1 — a first encounter with SoftBank Telecom

Start with the simplest possible case. Write down what SoftBank Telecom claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 SoftBank Telecom 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 SoftBank Telecom 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 SoftBank Telecom

In research: SoftBank Telecom appears in 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 SoftBank Telecom 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: SoftBank Telecom is common in secondary-school and first-year university syllabi. It links to neighbouring topics Japan Railway companies, Japanese company stubs, SoftBank Group, so understanding it makes those chapters shorter.
In everyday life: Look for SoftBank Telecom 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.
