Ikanos Communications 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 Ikanos Communications rather than just read about it. In short: Ikanos Communications, Incorporated was a provider of semiconductor and software products for use in homes. It was headquartered in Fremont, California.

Key takeaways

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

Reference excerpt

Ikanos Communications, Incorporated was a provider of semiconductor and software products for use in homes. It was headquartered in Fremont, California. The company’s digital subscriber line, communications processors and other products were used in customer premises equipment from network equipment manufacturers and telecommunications service providers.

History On December 10, 2001, the founder and chief technology officer of Ikanos, Behrooz Rezvani, announced he was editor of the Institute of Electrical and Electronics Engineers (IEEE) draft standard for Ethernet in the first mile over copper. On August 24, 2009 Ikanos acquired Conexant's Broadband Access product line for about $54 million in cash. It also announced an investment of $42 million from Tallwood Venture Capital. In June 2010, John Quigley replaced Michael Gulett as chief executive (who left in April). He was the fifth CEO in six years. A U.S. appeals court on May 25, 2012 revived a shareholder lawsuit accusing Ikanos of failing to properly disclose known defects in its semiconductor chips at the time it was conducting a 2006 stock offering. In August 2015, Ikanos was acquired by Qualcomm Atheros in a deal worth around $47 million, with Qualcomm taking on $20 million of liabilities from Ikanos. In August 2016 Qualcomm Atheros has closed its recently acquired Ikanos operations.

Worked examples

Example 1 — a first encounter with Ikanos Communications

Start with the simplest possible case. Write down what Ikanos Communications 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 Ikanos Communications 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 Ikanos Communications 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 Ikanos Communications

In research: Ikanos Communications 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 Ikanos Communications 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: Ikanos Communications is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1999 establishments in California, Companies based in Fremont, California, Defunct computer companies based in California, so understanding it makes those chapters shorter.
In everyday life: Look for Ikanos Communications 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.
