IBM 1015 (terminal)

IBM 1015 (terminal) 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 1015 (terminal) rather than just read about it. In short: The IBM 1015 is a display terminal for the IBM System/360. IBM suggested that it be used for phone-based customer support.

Key takeaways

IBM 1015 (terminal) 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 1015 (terminal) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IBM 1015 (terminal) from memory before moving on to harder problems.

Reference excerpt

The IBM 1015 is a display terminal for the IBM System/360. IBM suggested that it be used for phone-based customer support.

History It was exhibited during the 1964 introduction of the IBM System/360 and included in the official System Summary. Other display devices introduced and co-marketed by IBM were the IBM 2250 and the IBM 2260.

Product description The screen was round, and it sat forward and above a keyboard. The display area could hold 30 lines, each with up to 40 characters, selected from A–Z, 0–9, and 26 special characters. Output was 650 characters per second. It came with a desk. Up to ten 1015s could be connected to the IBM 1016 Control Unit or the IBM 1414 Input/Output Synchronizer.

Worked examples

Example 1 — a first encounter with IBM 1015 (terminal)

Start with the simplest possible case. Write down what IBM 1015 (terminal) 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 1015 (terminal) 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 1015 (terminal) 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 1015 (terminal)

In research: IBM 1015 (terminal) 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 1015 (terminal) 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 1015 (terminal) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 1964, Computer hardware stubs, so understanding it makes those chapters shorter.
In everyday life: Look for IBM 1015 (terminal) 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.
