MIDnet

MIDnet 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 MIDnet rather than just read about it. In short: Grants were submitted to the National Science Foundation in the Spring of 1986, and in the Summer of 1986 NSF approved funding. In September 1987, MIDnet was the first NSFNET regional backbone network to become fully operational.

Key takeaways

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

Reference excerpt

Grants were submitted to the National Science Foundation in the Spring of 1986, and in the Summer of 1986 NSF approved funding. In September 1987, MIDnet was the first NSFNET regional backbone network to become fully operational. The NSFNET regional backbone networks were the precursors to the Internet. MIDnet initially connected Iowa State University, Kansas State University, Oklahoma State University, the University of Kansas, the University of Missouri, the University of Nebraska–Lincoln, the University of Oklahoma, and Washington University in St. Louis with 56 kbit/s DDS leased telephone lines in a ring topology. The MIDnet ring was originally connected via a 56 kbit/s DDS leased telephone line from the Nebraska node to the NSFNET backbone. It was the first of the NSF-funded regional networks to become fully operational. MIDnet transitioned from a university-based organization to non-profit status in 1992. Two years later, Global Internet, a Palo Alto, California start-up, acquired MIDnet and its name was changed to Global Internet Network Services. The original board of directors of MIDnet were reorganized as the MIDnet Research and Higher Education Advisory Council. Global Internet sold the Network Services division to Verio, Inc. in 1997 and later sold the consulting and implementation division to Exodus Communications. MIDnet, Inc. is now a private foundation with a focus on data research and development of information for the research and education networking community.

Worked examples

Example 1 — a first encounter with MIDnet

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

In research
MIDnet 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 MIDnet 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
MIDnet is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, History of the Internet, University of Nebraska–Lincoln, so understanding it makes those chapters shorter.
In everyday life
Look for MIDnet 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 MIDnet in simple terms?

Grants were submitted to the National Science Foundation in the Spring of 1986, and in the Summer of 1986 NSF approved funding. In September 1987, MIDnet was the first NSFNET regional backbone network to become fully operational.

Why does MIDnet 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 MIDnet?

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.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on MIDnet.
