IBM 716

IBM 716 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 IBM 716 rather than just read about it. In short: The IBM 716 line printer was used with IBM 700/7000 series computers in the 1950s and 1960s. It was introduced on May 21, 1952 with the IBM 701 and withdrawn from marketing on July 14, 1969.

Key takeaways

IBM 716 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 IBM 716 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IBM 716 from memory before moving on to harder problems.

Reference excerpt

The IBM 716 line printer was used with IBM 700/7000 series computers in the 1950s and 1960s. It was introduced on May 21, 1952 with the IBM 701 and withdrawn from marketing on July 14, 1969.

Overview The 716 was based on IBM 407 accounting machine technology and had 120 rotary type wheels, each with 48 possible characters. It could print 150 lines per minute. It also supplied power to the IBM 711 card reader and 721 card punch. Only 72 characters could be transferred from IBM 7090 computer to the 716 in a single operation, but a full line could be printed at half speed. Characters were printed by sending bit patterns that corresponded to the impulses that a 407 would see when reading a punched card. A variant of the 716, the IBM 717 was used with the IBM 702 and IBM 705 computers.

Worked examples

Example 1 — a first encounter with IBM 716

Start with the simplest possible case. Write down what IBM 716 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 IBM 716 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 IBM 716 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 IBM 716

In research: IBM 716 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 IBM 716 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: IBM 716 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 1952, Computer hardware stubs, IBM 700/7000 series, so understanding it makes those chapters shorter.
In everyday life: Look for IBM 716 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 IBM 716 in simple terms?

The IBM 716 line printer was used with IBM 700/7000 series computers in the 1950s and 1960s. It was introduced on May 21, 1952 with the IBM 701 and withdrawn from marketing on July 14, 1969.

Why does IBM 716 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 IBM 716?

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.
