Treo 90

Treo 90 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 Treo 90 rather than just read about it. In short: The Treo 90 is a Palm OS PDA developed by Handspring. It was released on May 28, 2002.

Key takeaways

Treo 90 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 Treo 90 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Treo 90 from memory before moving on to harder problems.

Reference excerpt

The Treo 90 is a Palm OS PDA developed by Handspring. It was released on May 28, 2002. The Treo 90 was the only Treo model produced without an integrated cellular phone. When first released it was the smallest Palm OS device on the market.

Design The Treo 90 features a 12-bit standard (160x160) resolution color super-twisted nematic display, LED backlighting, a miniature QWERTY keyboard that replaces the usual Graffiti on other PDAs, an infrared port and an SD card slot.

ROM update The original Palm OS (4.1H) lacks SDIO support and reportedly has trouble formatting 128 megabyte SanDisk cards. The Treo 90 Updater addresses this problem and adds some other edits. The update is not a software patch but is burned into ROM. The ROM 4.1H3 update allows the use of SD Cards up to 1 GB (confirmed). Additionally the new SDIO capability allows users to expand the device's features with two expansion cards: the Palm Bluetooth card, which allows the Treo 90 to access the Internet, email and messages wirelessly with a Bluetooth-enabled mobile phone and MARGI Systems Presenter-and-Go which connects the Treo 90 directly to digital LCD projectors or other VGA devices to show business presentations stored on the Treo in full color.

Worked examples

Example 1 — a first encounter with Treo 90

Start with the simplest possible case. Write down what Treo 90 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 Treo 90 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 Treo 90 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 Treo 90

In research: Treo 90 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 Treo 90 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: Treo 90 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 68k-based mobile devices, Computer hardware stubs, Palm OS devices, so understanding it makes those chapters shorter.
In everyday life: Look for Treo 90 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.
