PERM (computer)

PERM (computer) 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 PERM (computer) rather than just read about it. In short: PERM (German: Programmierbare (Programmgesteuerte) Elektronische Rechenanlage München, lit. 'Munich Programmable (Program Controlled) Electronic Computing System') is a stored-program-controlled electronic computer, built in Munich under the auspices of Hans Piloty and Robert Sauer 1952–1956. Some jokingly called it Pilotys erstes RechenMonster ('Piloty's first calculating monster').

Key takeaways

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

Reference excerpt

PERM (German: Programmierbare (Programmgesteuerte) Elektronische Rechenanlage München, lit. 'Munich Programmable (Program Controlled) Electronic Computing System') is a stored-program-controlled electronic computer, built in Munich under the auspices of Hans Piloty and Robert Sauer 1952–1956. Some jokingly called it Pilotys erstes RechenMonster ('Piloty's first calculating monster'). It weighed several tons. The machine is now displayed in the informatics (computer science) exhibition of the Deutsches Museum München.

Worked examples

Example 1 — a first encounter with PERM (computer)

Start with the simplest possible case. Write down what PERM (computer) 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 PERM (computer) 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 PERM (computer) 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 PERM (computer)

In research: PERM (computer) 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 PERM (computer) 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: PERM (computer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 1956, Computer hardware stubs, Computers designed in Germany, so understanding it makes those chapters shorter.
In everyday life: Look for PERM (computer) 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 PERM (computer) in simple terms?

Why does PERM (computer) 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 PERM (computer)?

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.
