Here is a question about this article: For digital photo cameras ("digital still cameras"), an exposure index (EI) ratingcommonly called ISO settingis specified by the manufacturer such that the sRGB image files produced by the camera will have a lightness similar to what would be obtained with film of the same EI rating at the same exposure. The usual design is that the camera's parameters for interpreting the sensor data values into sRGB values are fixed, and a number of different EI choices are accommodated by varying the sensor's signal gain in the analog realm, prior to conversion to digital. Some camera designs provide at least some EI choices by adjusting the sensor's signal gain in the digital realm. A few camera designs also provide EI adjustment through a choice of lightness parameters for the interpretation of sensor data values into sRGB; this variation allows different tradeoffs between the range of highlights that can be captured and the amount of noise introduced into the shadow areas of the photo.
What is the answer to this question: How do some camera designs give some EI choices?

So... by adjusting the sensor's signal gain in the digital realm

Here is a question about this article: The two mature piano sonatas (No. 2, Op. 35, written in 1839 and No. 3, Op. 58, written in 1844) are in four movements. In Op. 35, Chopin was able to combine within a formal large musical structure many elements of his virtuosic piano technique"a kind of dialogue between the public pianism of the brilliant style and the German sonata principle". The last movement, a brief (75-bar) perpetuum mobile in which the hands play in unmodified octave unison throughout, was found shocking and unmusical by contemporaries, including Schumann. The Op. 58 sonata is closer to the German tradition, including many passages of complex counterpoint, "worthy of Brahms" according to the music historians Kornel Michaowski and Jim Samson.
What is the answer to this question: How many movements are in No. 2, Op. 35 and No. 3, Op 58?

So... four

Here is a question about this article: Following speculation that Sony was working on a 'slim' model, Sony officially announced the PS3 CECH-2000 model on August 18, 2009, at the Sony Gamescom press conference. New features included a slimmer form factor, decreased power consumption, and a quieter cooling system. It was released in major territories by September 2009. As part of the release for the slim model, the console logo ceased using the "Spider-Man font" (the same font used for the title of Sony's Spider-Man 3) and the capitalized PLAYSTATION 3. It instead reverted to a more traditional PlayStation- and PlayStation 2-like 'PlayStation 3' logo with "PS3" imprinted on the console. Along with the redesigning of the console and logo, the boot screen of all consoles changed from "Sony Computer Entertainment" to "PS3 PlayStation 3", with a new chime and the game start splash screen being dropped. The cover art and packaging of games was also changed.
What is the answer to this question: What would customers notice about the sound of the new, improved cooling system?

So...
quieter
