Pocket eDGe

Pocket eDGe 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 Pocket eDGe rather than just read about it. In short: The enTourage pocket eDGe is a discontinued combined tablet computer and e-book made by enTourage Systems Inc., a small company based out of McLean, Virginia. It is the first follow on to the original EnTourage eDGe released earlier in 2010.

Key takeaways

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

Reference excerpt

The enTourage pocket eDGe is a discontinued combined tablet computer and e-book made by enTourage Systems Inc., a small company based out of McLean, Virginia. It is the first follow on to the original EnTourage eDGe released earlier in 2010. The device runs Google's Android platform, version 2.2. It is called by the manufacturer as the world's first mini-dualbook". On May 23, 2011 the company announced that it would no longer manufacture and distribute the Pocket Edge.

Features The Pocket eDGe is a dual-screen device. One screen is a touch-sensitive 6.0 inch E Ink display, while the other screen is a full-color 7.0 inch LCD touch screen. The color display side runs Android. Unlike most android devices, entourage pocket edge has its own suite of applications, rather than using the Android Market. Both displays are touchscreens, and the interface of the device provides interaction between the two according to appropriate actions and data formats. The LCD is designed for multimedia display, whereas the e-Ink screen is designed for reading and, in the corresponding mode, the ink can be marked as handwriting, indexed, searched, and even converted to text.

Worked examples

Example 1 — a first encounter with Pocket eDGe

Start with the simplest possible case. Write down what Pocket eDGe 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 Pocket eDGe 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 Pocket eDGe 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 Pocket eDGe

In research: Pocket eDGe 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 Pocket eDGe 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: Pocket eDGe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dedicated ebook devices, Electronic paper technology, Linux-based devices, so understanding it makes those chapters shorter.
In everyday life: Look for Pocket eDGe 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.
