Qosmio

Qosmio 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 Qosmio rather than just read about it. In short: The Qosmio (KOS-mee-oh) series was Toshiba's consumer-marketed line of high performance multimedia-oriented desktop replacement laptops. The first Qosmio laptop was released on July 25, 2004 as the E15-AV101 with a 1.7 GHz Intel Pentium M CPU, 512 megabytes of DDR SDRAM, and a 15-inch XGA 1024x768 screen.

Key takeaways

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

Reference excerpt

The Qosmio (KOS-mee-oh) series was Toshiba's consumer-marketed line of high performance multimedia-oriented desktop replacement laptops. The first Qosmio laptop was released on July 25, 2004 as the E15-AV101 with a 1.7 GHz Intel Pentium M CPU, 512 megabytes of DDR SDRAM, and a 15-inch XGA 1024x768 screen. Toshiba's most powerful laptop has undergone many revisions, with focus shifting from high-end multimedia functionality to heavy gaming. The last line under the Qosmio name, the X70 series, was released in 2013, featuring an Intel Core i7 processor with up to 32 GB of DDR3 SDRAM and an Nvidia GeForce GTX 770M as well as a 17.3-inch Full HD display.

History The Toshiba Qosmio G35-AV650 was the first production notebook made available with an HD DVD-compatible drive. The Qosmio G35 line also functioned as a Digital Video Recorder as it contains an integrated TV tuner. Focus for the Qosmio had shifted from full-fledged multimedia to high-end gaming with high-quality graphics and audio. This can be seen in the first Qosmio, the E15-AV101, which offered a 1.7 GHz Intel Pentium M 735 CPU, 512 MB of DDR SDRAM, a 15-inch XGA 1024x768 screen, and an Nvidia GeForce FX Go5200 with 64 MB of dedicated DDR video memory, all of which were relatively powerful for the time. The X500 had an Intel Core i7 processor with up to 6 GB of DDR3 SDRAM as well as an 18.4 inch HD display powered by an Nvidia GeForce GTX 460M with 1.5 GB of GDDR5 video memory. These components, on the other hand, are on the high end of the spectrum in performance. This original model launched in 2004 with an international marketing campaign. The campaign was featured in every major publication, as well as an ambitious digital campaign, one of the first for a major laptop release at that time.

Models

F45 series Released on February 7, 2007, the Toshiba F45 series was an upgraded line of F40 laptops with advertised features including Dolby Home Theater and a built-in subwoofer. The basic specs included an Intel Core 2 Duo T5450 Processor at 1.66 GHz, with 2 MB of L2 cache attached to a 64-bit 667 MHz FSB. It had 2 GB of PC2-5300 DDR2 SDRAM. The built-in DVD drive supported "+/- R double layer" technology. The integrated graphics processor was the Mobile Intel GMA X3100 with 8-256 MB of video memory shared with the system memory, the screen was a 15.4-inch "TruBrite" display with a 1280x800 native resolution (WXGA), and hard drives were about 200 GB in size (varied by model). 32-bit editions of Windows Vista Home Premium or Ultimate were normally shipped with the systems.

Toshiba F45 models include: AV410, AV411, AV411B, AV412, AV413, AV423 and AV425

X300 series Released on January 4, 2009, the Qosmio X300 models offered not only HD DVD reading capabilities but also writing capabilities in either 15 gigabyte or 30 gigabyte capacities. External audio/video controls were also added to allow for one touch recording. A remote control is available to allow control within 20 feet of the laptop. The X305 is red with flames around its back. The X300 replaces the Satellite X200.

Toshiba Satellite X305 Models include: Q701, Q705, Q706, Q708, Q710, Q711, Q7113, Q712, Q715, Q720, Q7201, Q7203, Q725, Q7253, SP6828A, SP6828C, SP6828R. Models with both Core 2 Duo and Core 2 Quad processors were sold, along with the option of a GeForce 9700M GTS (individual cards; not SLI)

X500 series Released on October 22, 2009, the X500 comes in many models, including: the X505-Q830, X505-Q832, X505-Q850, X505-Q870, X505-Q875, X505-Q880, and the X500-S1801. The X500 series introduced multi-touch capabilities to its touchpad. It supports Blu-ray playback, but only some models are able to write Blu-ray disks. The X500 had a much simpler black and red accented design than its predecessor, the X300.

Other X500 models include: X500-PQX33A, X500-Q840S, X500-Q895S, X500-Q900S, X500-Q930X, X500-S1801, X500-S1811, X500-S1812, X500-S1812X

X770 series The Qosmio X770 series was introduced on June 14, 2011, followed by the X775 series.

X870 series Released in 2012 was the Qosmio X870 series, with the specifications including a new "Ivy Bridge" Intel Core i7 processor, a Nvidia GeForce GTX 670M graphics processor with 3 GB of video memory, a 17.3-inch 1920x1080 TN display, 16 GB of DDR3 memory clocked at 1600MHz, and a 2 TB hard disk drive.

X70/75 series Released in 2013 was the Qosmio X70-A series, with a Nvidia GeForce GTX 770M graphics processor designed for gaming and multimedia usage. Subsequently, released in late 2014 was the Qosmio X70-B series for the European market, with a significantly less powerful GPU, an AMD Radeon R9 M265X.

Specifications

Expandability This section encompasses current models only:

2 DDR3 memory slots supporting up to 8GB 5-in-1 Media Adapter supporting Secure Digital Card, Memory Stick, Memory Stick Pro, MultiMediaCard, and xD-Picture Card ExpressCard/54 1 each of VGA and HDMI ports

Issues The Qosmio F10 and G10 series, both early models, were plagued with chipset issues. When a defective unit was under considerable load for an extended period of time, the video chipset on the board was known to fail, causing considerable interference on the display and/or complete motherboard failure.

Worked examples

Example 1 — a first encounter with Qosmio

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

In research: Qosmio 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 Qosmio 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: Qosmio is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer-related introductions in 2004, Consumer electronics brands, Gaming laptops, so understanding it makes those chapters shorter.
In everyday life: Look for Qosmio 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.
