Linutop

Linutop 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 Linutop rather than just read about it. In short: The Linutop is a small, light, environmentally friendly nettop computer containing a metal case and no moving parts, that runs the Linutop OS (a customized version of Linux based on the Xubuntu and Ubuntu/XFCE distribution). It is sold by Linutop SAS of Paris, France.

Key takeaways

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

Reference excerpt

The Linutop is a small, light, environmentally friendly nettop computer containing a metal case and no moving parts, that runs the Linutop OS (a customized version of Linux based on the Xubuntu and Ubuntu/XFCE distribution). It is sold by Linutop SAS of Paris, France. Linutop Kiosk software and Linutop Tv server offer a full Digital signage solution. A variety of QT applications oriented towards secure web browsing and digital signage are available in the Operating system. Linutop is multimedia-capable and offers line-out/mic-in for sound. The device can be configured easily into a LTSP thin client. Linutop is suited for use in internet cafés, public libraries and schools.

History

Linutop 1 The first device was based on the ThinCan reference design from Estonian company Artec Group.

Linutop 2 On February 20, 2008, the company unveiled the Linutop 2 based on the FIC ION A603 mini PC (like Works Everywhere Appliance). Linutop 2 had a stronger Geode processor and more memory, allowing it to run OpenOffice.org. It has 512 MB RAM and 1 GB flash memory storage.

Specifications

Linutop XS The Linutop XS is the smallest computer offered by Linutop. Due to its small size, and the absence of fan making it very silent, it is often hidden behind the dynamic display screens by professionals. The compact Linutop XS comes in a small aluminum case with dimensions 9 cm × 6 cm × 2 cm (3.5 in × 2.3 in × 0.8 in) for a weight of 92 grams (3 oz) and a power consumption of 3 watts. On board, there is a processor running at 900 MHz, a RAM of 1 GB and an 8 GB flash memory. Connectors: HDMI, mini-jack audio, RJ-45 Ethernet, four USB 2.0, 5-volt micro USB power. The Linutop XS is a professional packaging of the Raspberry Pi 2 and incorporates a 1080p HD video Hardware accelerator. With this compact configuration, designed for the fields of education, transport, trade and health for the dissemination of information.

Linutop 6 Linutop 6 is the most powerful Linutop. The Linutop 6 microcomputer is in the form of a small fanless metal case with dimensions 9.5 cm × 9.1 cm × 3.6 cm (3.7 in × 3.6 in × 1.4 in) for a weight of 350 grams (12 oz) and an energy consumption of 14 watts. On board, there is an Intel ATOM x5-Z8350 processor, a 2 GB RAM and a 16 GB flash memory. Connectors: HDMI, RJ-45 Ethernet, four USB 2.0, 5-volt power supply. With this configuration, the Linutop 6 computer targets a varied use where compactness and power are required.

Linutop TV Linutop tv has been designed to manage a network of connected digital signage screens and allows centralized management via an HTTP interface. Each screens needs a player (PC, Raspberry Pi, or Linutop Mini PC), running Linutop Kiosk software, connected to the server in order to update display content automatically. Linutop tv is a server solution available in two versions:

SaaS (or "cloud") server: accessible via Internet. Private (local) server: works on the local network. This solution is often used in corporations intranet. It offers maximum security.

Worked examples

Example 1 — a first encounter with Linutop

Start with the simplest possible case. Write down what Linutop 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 Linutop 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 Linutop 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 Linutop

In research: Linutop 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 Linutop 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: Linutop is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer companies of France, Computers and the environment, Linux-based devices, so understanding it makes those chapters shorter.
In everyday life: Look for Linutop 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.
