Pyongyang Touch

Pyongyang Touch 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 Pyongyang Touch rather than just read about it. In short: The Pyongyang Touch (Korean: 평양 타치) is a line of smartphone, with its first version launched in North Korea in 2014 and likely produced by the Chinese company Uniscope. It is named after the capital of the country, Pyongyang.

Key takeaways

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

Reference excerpt

The Pyongyang Touch (Korean: 평양 타치) is a line of smartphone, with its first version launched in North Korea in 2014 and likely produced by the Chinese company Uniscope. It is named after the capital of the country, Pyongyang. Not much is known about the technical data, but the phone is believed to run a modified version of Android. Externally, it resembles the iPhone 3G and is available in white, pink, and blue. Since access to the Internet is denied to a large part of the population in North Korea, there is only access to the Intranet Kwangmyong. It is particularly popular among the younger population, according to Choson Sinbo.

Models

Pyongyang 2413

Pyongyang 2418

The device has a "panorama" function and had a flashlight app as default. The user can use Photoshop to edit photos they take with the phone's camera. The phone also offers medical self-diagnosis services and scientific agricultural apps.

Pyongyang 2421

The device included a security feature that did not work properly.

Pyongyang 2423

The device is able to make Word documents, Excel files and PowerPoints. According to a report by The Stimson Center, the device (along with the Pyongyang 2413) has been jailbroken by North Korean citizens to circumvent surveillance measures and media restrictions on the devices.

Pyongyang 2425

The device includes wireless charging, an advanced camera, and facial recognition.

Pyongyang 2428 The device uses Android 8.1 as its operating system.

Worked examples

Example 1 — a first encounter with Pyongyang Touch

Start with the simplest possible case. Write down what Pyongyang Touch 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 Pyongyang Touch 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 Pyongyang Touch 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 Pyongyang Touch

In research: Pyongyang Touch 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 Pyongyang Touch 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: Pyongyang Touch is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mobile computer stubs, Mobile phones, Mobile phones introduced in 2014, so understanding it makes those chapters shorter.
In everyday life: Look for Pyongyang Touch 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.
