Nanocomputer

Nanocomputer 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 Nanocomputer rather than just read about it. In short: Nanocomputer refers to a computer smaller than the microcomputer, which is smaller than the minicomputer. Microelectronic components that are at the core of all modern electronic devices employ semiconductor transistors.

Key takeaways

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

Reference excerpt

Nanocomputer refers to a computer smaller than the microcomputer, which is smaller than the minicomputer. Microelectronic components that are at the core of all modern electronic devices employ semiconductor transistors. The term nanocomputer is increasingly used to refer to general computing devices of size comparable to a credit card. Modern single-board computer such as the Raspberry Pi and Gumstix would fall under this classification. Arguably, smartphones and tablets would also be classified as nanocomputers.

Future computers with features smaller than 10 nanometers Die shrink has been more or less continuous since around 1970. A few years later, the 6 μm process allowed the making of desktop computers, known as microcomputers. Moore's Law in the next 40 years brought features 1/100 the size, or ten thousand times as many transistors per square millimeter, putting smartphones in every pocket. Eventually computers will be developed with fundamental parts that are no bigger than a few nanometers. Nanocomputers might be built in several ways, using mechanical, electronic, biochemical, or quantum nanotechnology. There used to be consensus among hardware developers that it is unlikely that nanocomputers will be made of semiconductor transistors, as they seem to perform significantly less well when shrunk to sizes under 100 nanometers. Nevertheless developers reduced microprocessor features to 22 nm in April 2012. Moreover, Intel's 5 nanometer technology outlook predicts 5 nm feature size by 2022. The International Technology Roadmap for Semiconductors in the 2010s gave an industrial consensus on feature scaling following Moore's Law. A silicon-silicon bond length is 235.2 pm, which means that a 5 nm-width transistor would be 21 silicon atoms wide.

Worked examples

Example 1 — a first encounter with Nanocomputer

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

In research
Nanocomputer 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 Nanocomputer 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
Nanocomputer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Classes of computers, Microcomputer stubs, Nanoelectronics, so understanding it makes those chapters shorter.
In everyday life
Look for Nanocomputer 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 Nanocomputer in simple terms?

Nanocomputer refers to a computer smaller than the microcomputer, which is smaller than the minicomputer. Microelectronic components that are at the core of all modern electronic devices employ semiconductor transistors.

Why does Nanocomputer 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 Nanocomputer?

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 Nanocomputer.
