Internet Mail 2000

Internet Mail 2000 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 Internet Mail 2000 rather than just read about it. In short: Internet Mail 2000 is an Internet mail architecture proposed by Daniel J. Bernstein (and in subsequent years separately proposed by several others), designed with the precept that the initial storage of mail messages be the responsibility of the sender, and not of the recipient as it is with the SMTP-based Internet mail architecture.

Key takeaways

Internet Mail 2000 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Internet Mail 2000 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Internet Mail 2000 from memory before moving on to harder problems.

Reference excerpt

Internet Mail 2000 is an Internet mail architecture proposed by Daniel J. Bernstein (and in subsequent years separately proposed by several others), designed with the precept that the initial storage of mail messages be the responsibility of the sender, and not of the recipient as it is with the SMTP-based Internet mail architecture. Whereas the SMTP-based Internet mail architecture has a close analogue in the architecture of paper mail, this is not the case for Internet Mail 2000. Its architecture depends on various things that are unique to the natures of the Internet and to electronic messages. One of its goals is to reduce spam.

Implementations Over the years since Daniel J. Bernstein proposed it, several attempts have been made to design and to implement a real Internet Mail 2000 system, with varying degrees of achievement. The closest thing to a concrete, open implementation of the system is Meng Weng Wong's StubMail, which was presented at Google in July 2006.

Worked examples

Example 1 — a first encounter with Internet Mail 2000

Start with the simplest possible case. Write down what Internet Mail 2000 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 Internet Mail 2000 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 Internet Mail 2000 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 Internet Mail 2000

In research: Internet Mail 2000 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 Internet Mail 2000 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: Internet Mail 2000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Email, so understanding it makes those chapters shorter.
In everyday life: Look for Internet Mail 2000 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.
