Nefsis

Nefsis 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 Nefsis rather than just read about it. In short: Nefsis Corporation is a communications technology company. It was an early developer of real-time communications software and the first to use cloud computing in the videoconferencing industry.

Key takeaways

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

Reference excerpt

Nefsis Corporation is a communications technology company. It was an early developer of real-time communications software and the first to use cloud computing in the videoconferencing industry. Nefsis offers multipoint video conferencing with integrated voice and live collaboration solutions for small to medium-sized business and distributed enterprise customers.

History Nefsis was founded in 1998 by Allen Drennan as WiredRed Corporation. The company name was changed to Nefsis Corporation in 2010. In 1998 through 2000 the company developed and sold a VPN-like, full-duplex, multipoint communications software product called e/pop that supported several applications including presence management, instant messaging, multiparty VoIP, and remote control. In 2001 the company introduced version 3 of its e/pop software, including server-to-server pipes, providing a unique method of relaying presence status and secure instant messaging across firewalls and proxies in multi-office, distributed networks. e/pop v3.0 received Network Computing Editor's Choice award in September, 2004, for enterprise instant messaging due in part to its secure multi-office capabilities. The company's real-time software technology was distributed under OEM license by Sony Online Entertainment in 2003 as the multipoint VoIP software engine in the PlanetSide multiplayer online game. Commencing 2004, NewHeights Software Corporation licensed the company's technology to power presence, IM, and web conferencing features in several softphone products sold under the NewHeights and Mitel brands. These OEM integrations were noteworthy at the time as they added multipoint VoIP and web conferencing to these online gaming and softphone applications, respectively. In May, 2004, the company added multipoint video as another feature of its on-premises, web conferencing software products. In 2005 the company started offering its software under hosted service agreements (software-as-a-service). After several years in development, the company introduced cloud computing and parallel processing technology to its customers commencing in 2008. The new video conferencing online service was introduced under the Nefsis brand, which later became the company name. The company was cited by European CEO Magazine and market research firm Frost & Sullivan in 2009 as the first to use cloud computing in a multipoint video conferencing online service. Nefsis has been used for corporate video conferencing and online meetings, as a business continuity tool during inclement weather, and in specialty applications such as training, telemedicine, video arraignment, and video remote interpreting among others. In 2011, Nefsis was acquired by Brother Industries.

Worked examples

Example 1 — a first encounter with Nefsis

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

In research: Nefsis 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 Nefsis 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: Nefsis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Teleconferencing, Videotelephony, Web conferencing, so understanding it makes those chapters shorter.
In everyday life: Look for Nefsis 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 Nefsis in simple terms?

Nefsis Corporation is a communications technology company. It was an early developer of real-time communications software and the first to use cloud computing in the videoconferencing industry.

Why does Nefsis matter?

Because it connects several 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 Nefsis?

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.
