A computer is a machine that manipulates data according to a list of instructions.
use today is the embedded computer. Embedded computers are small, simple devices that are used to control other devices — for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and children's toys.
How do you choose a proper desktop computer system that will meet your computing needs?
ping a 16-layerread-only optical disc with a capacity of 400 gigabytes for the first time in the world*1. Itsper-layer capacity is 25 gigabytes, which is the same as that of a Blu-ray Disc (BD). Thismultilayer technology will also be applicable to multilayer recordable discs. Thisdevelopment has bolstered Pioneer’s confidence in the feasibility of a large-capacity opticaldisc, which is expected to become necessary in the near future.For multilayer optical discs, it has been difficult to obtain clear signals from each recordinglayer in a stable manner due to crosstalk from adjacent layers and transmission loss.Utilizing the optical disc production technology that it has developed in the DVD field,Pioneer solved these problems by, among other things, using a disc structure that canreduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playbackhigh-quality signals from every layer.As for the read-out system, Pioneer achieved stability in the playback of recorded signals byemploying a wide-range spherical aberration compensator and light-receiving element thatcan read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism.Since the optical specifications of the objective lens, such as NA (Numerical Aperture)*2, arethe same as those for the existing BD discs, it is possible to maintain compatibility betweenthe new 16-layer optical disc and the BD discs.The 16-layer optical disc technology, capable of storing much more data than theconventional discs on one disc, will greatly reduce the number of discs to be used andtherefore contribute to the conservation of resources.Pioneer will present the details of this research at the International Symposium on OpticalMemory and Optical Data Storage 2008 (ISOM/ODS2008 ) to be held in Hawaii from July13.| - | Freedom to connect without depending upon conventional telephony networks |

What's the difference between a standard keyboard and a gaming keyboard? Well, in this case, a honking great big LCD, 18 programmable macro keys, two USB ports and a bright-LED backlight!
The Logitech G15 is marketed as a Gamers keyboard when in fact, I think it would be more accurately described as a multipurpose keyboard. I don't really call myself a huge gamer - probably only clocking about 5 hours a week - however I bought this keyboard anyway, with the impression that it would help improve my general computer experience. This keyboard has perhaps been my most useful purchase to date.The backlight is a feature that appears in a lot of gaming keyboards now, and is more for show than anything else. To a touch typist, backlit keys don't really offer any advantage, however, it is invaluable on the LCD screen which enables you to see the display in the dark. For someone who sits in the dark until the early hours of the morning, this really is a priceless feature.
The backlight has 3 distinct brightness settings: off, low or high. These can be changed by a button at the top of the keyboard, which toggles between these three states.The only bad thing I can find to say about this is that I wish there was a brighter option. I know it's probably limited by what the USB port can provide, but after the first week or two, the LEDs don't seem to look as bright as they did at first.
The LCD Screen is supported natively in numerous different games, and even more with patches. These include, but are not limited to: Enemy Territory: Quake Wars, World of Warcraft, Neverwinter Nights 2 and Unreal Tournament 2004, with the list always growing. In addition to this, various applications have added support, such as the popular Xfire IM and Fraps.
As of yet, Logitech is yet to release a program to easily create your own applets, however, the screen is fully compatible with LCD studio, which is a third party application allowing you to do just that. Enthusiasts can look into their SDK which is released free of charge to help third party developers interface with the LCD.The keyboard has 18 programmable keys - officially named 'G keys' - arranged in 3 blocks of 6 keys. Each of the keys can be programmed to perform up to 3 unique tasks: either a key macro which can be set directly from the keyboard or an action (such as opening an application) which can be set through the provided software. By arranging these functions into 3 key sets, you can unlock a possible 54 key functions which (if you can remember what each of them does!), saves a lot of time when multitasking or performing repetitive tasks.
Available on the internet is a card template to place on the keyboard, which can be downloaded and cut out to wrap around the 18 keys to identify them, which is when the 'G keys' show their full potential.Just underneath the LCD screen are full media controls including fast forward, track skip, rewind, stop, play and pause as well as a large scroll wheel for precise volume control. With the media LCD applet, this makes it perfect for changing music in-game.
Next to the volume control is a toggle switch, which on its own seems to justify the price. In essence, all it does is disable two keys on the keyboard, but what it has done is saved hours of maximizing and minimizing windows. When on, the two most rarely used, but most often mishit keys - the Windows Keys - are disabled, meaning that when your little finger accidently swipes over them on the way to the control key, you don't end up out of the action for 5 minutes wondering what just happened.Logitech has equipped the G15 keyboard with two low-power USB1.1 ports at the top of the keyboard. Whilst they can't really be used to power much more than a mouse or a headset, they're really handy for easy access and they serve their purpose.
On the underside of the keyboard are a few indented grooves leading from the USB ports to the sides of the keyboard. These are designed to let you feed the cables from the USB devices through, ideally creating a tidier workspace. A good idea, but in practice they really don't offer the grip and support required, and more often than not, the cables just pop out.On the supplied CD are two pieces of software. One is the Logitech G-series Keyboard Profiler, which handles the macros associated with the programmable keys. The other is the Logitech LCD Manager, which handles what's displayed on the LCD on the keyboard. Both of these need to be running for the respective functions on the keyboard to work properly.
At the time of writing, there are software updates for both of these available on the Logitech website, offering bug fixes and additional features. Out of the box, the keyboard works with Vista - but just! If you use Vista, you'll want to get the latest software updates from the Logitech website.To begin with, the LCD screen cannot be tilted, and from what I can tell is significantly smaller. I can only assume this is to make the keyboard more sturdy and smaller; however I'm sure this must hinder the viewing angle of the LCD.
Also in the revised model, there are only 6 'G keys' instead of the 18 on the original model, the scroll volume wheel has been replaced in favour of two buttons, and the colour scheme has been changed from blue to orange.With the arrival of the revised model, Logitech has discontinued support for the original model meaning the only place you can probably pick one of these up is either existing stock or e-bay. I really think this is a shame as the new model looks clearly inferior to the original, and for the same price, it almost looks like a bit of a rip-off.
The keyboard seems robust, and it's certainly lasted me more than the 5 months that my old one did. I can see this staying on my desk for a good time to come!
