NUSSE

NUSSE 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 NUSSE rather than just read about it. In short: NUSSE (Norsk Universell Siffermaskin, Sekvensstyrt, Elektronisk) was the first Norwegian electronic computer. It was constructed from 1950 through 1955 and unveiled at the University of Oslo in 1954 to an enthusiastic reception.

Key takeaways

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

Reference excerpt

NUSSE (Norsk Universell Siffermaskin, Sekvensstyrt, Elektronisk) was the first Norwegian electronic computer. It was constructed from 1950 through 1955 and unveiled at the University of Oslo in 1954 to an enthusiastic reception. The machine is considered to have played an important role in developing the commercial use of computers in Norway. The environment around the NUSSE computer was the birthplace of the AUTOKON CAD/CAM system. The computer is now on exhibit at the Norwegian Museum of Science and Technology.

Technical specifications NUSSE used punched tape for input and output and had a 32-bit word length. Its rotating drum memory stored 512 words. Operations took between 1 and 16 milliseconds; the machine could perform about 500 additions per second and consumed 1.5 kW of power.

Worked examples

Example 1 — a first encounter with NUSSE

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

In research: NUSSE 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 NUSSE 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: NUSSE is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950s computers, 1954 in Norway, Computer-related introductions in 1954, so understanding it makes those chapters shorter.
In everyday life: Look for NUSSE 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 NUSSE in simple terms?

Why does NUSSE 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 NUSSE?

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.
