Jim Ellis (computing)

Jim Ellis (computing) 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 Jim Ellis (computing) rather than just read about it. In short: James Tice Ellis (May 6, 1956 – June 28, 2001) was an American computer scientist best known as the co-creator of Usenet, along with Tom Truscott. Ellis was born in Nashville, Tennessee to Henry Ellis (an auditor and teacher) and Elsa Ellis.

Key takeaways

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

Reference excerpt

James Tice Ellis (May 6, 1956 – June 28, 2001) was an American computer scientist best known as the co-creator of Usenet, along with Tom Truscott. Ellis was born in Nashville, Tennessee to Henry Ellis (an auditor and teacher) and Elsa Ellis. James Ellis grew up in Orlando, Florida. Before developing Usenet, Ellis attended Duke University. After graduating, Ellis worked for the Microelectronics Center of North Carolina in Research Triangle Park, N.C. He later worked as an Internet security consultant for Sun Microsystems. He was also Manager of Technical Development at CERT. He invented the word Usenet. Ellis and Truscott were awarded the 1995 USENIX Lifetime Achievement Award.

Personal life and death Ellis and his wife, Carolyn, had two children. He died of non-Hodgkin lymphoma, a form of blood cancer, at his home in Harmony, Pennsylvania on June 28, 2001. He was 45.

Worked examples

Example 1 — a first encounter with Jim Ellis (computing)

Start with the simplest possible case. Write down what Jim Ellis (computing) 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 Jim Ellis (computing) 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 Jim Ellis (computing) 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 Jim Ellis (computing)

In research: Jim Ellis (computing) 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 Jim Ellis (computing) 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: Jim Ellis (computing) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 2001 deaths, American computer scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Jim Ellis (computing) 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.
