DVD disk now can be found easily in everywhere. Usually, DVD disk comes in 4.5 gigabytes and 8.5 gigabytes capacities. However, in five years later we will see a revolution in DVD disk. Min Gu, an Australian academic and professor of Optoelectronics at Swinburne University of Technology claims that a single DVD disk named Ultra-DVD that able to store 10,000 times than the current DVD will be discovered soon. This particular disk will support the three-dimensional TV, and ultra high definition image.

The Ultra-DVD has the size and thickness as the conventional DVD disk. The main difference is the disk using nano technology in order to be able to store large amounts of file. Scientists believe such disk can be sold in five years and will be a revolution in storing film, music and data.

Professor Min Gu, who led this research in Melbourne Australia said the disk can contain 200,000 movies. "Materials with nano structure can be paired to the disk to increase the data capacity without the need to increase the size," he said.

Nowadays, a single DVD disk has an ability to store 4.5 - 8.5 gigabytes data for a sufficient length movie, with its additional features, and the soundtrack. Fortunately, DVD disk technology has start been shifted by a Blu-ray disk, which has a 50GB capacity. Five years from now, according to Professor Min Gu, it will be shifted to Ultra-DVD which has a 10 terabyte or 10,000 GB capacity.

• Wireless networking between laptops and desktop computers, or desktops that are in a confined space and little bandwidth is needed.
• Peripherals such as mice, keyboards, and printers.
• Cell phones with Bluetooth technology have been sold in large numbers, as they are able to connect to computers, PDAs (Personal Data Assistant), and various other devices. The standard also includes the support for more powerful and longer range devices.
• The transfer of files, images and MP3, between mobile phones.
• Certain MP3 players and digital cameras to transfer files to and from computers.
• Bluetooth technology headsets for smart phones and cell phones.
• Data logging equipment that transmits data to a computer via Bluetooth technology.

For Bluetooth, there are literally hundreds of different applications and devices available for you to use or purchase. Bluetooth, now, is the most popular wireless technology in the world. It's very reliable, very dependable, and very hard to crack into.

There are many other applications for Bluetooth in development now, many of which plan to take the wireless age to the next level. Video game systems are using Bluetooth technology as well, for their wireless controllers. This is great news for gaming fans, as Bluetooth offers the best in wireless data transmission.

If you still curious about Bluetooth development, you may search it on the internet. You can find all sorts of information, especially when it comes to Bluetooth. As the future arrives, you can expect Bluetooth to bring bigger and better things.

Gone are the days of the console being 'just' a games machine. These days, your average console gives you access to everything from the net to the latest movie trailers, not to mention your own virtual world. Indeed, Sony is so pleased with its PlayStation Network for the PS3, that it wants to extend it to other devices.

In an interview with Nikkei, Sony CEO Sir Howard Stringer said: 'We will be expanding the PlayStation Network to hardware other than the PS3' because limiting the Network to PS3 consoles 'puts a limit on the scale of the network possible.' It's hardly surprising. After all, as he rightly points out, the more people use the network, the more money is made by both Sony and its partners. More users could also tempt more companies to sign up with Sony too - video rental company Netflix is just one that's rumoured to be considering the Sony platform.

How and when this expansion takes place isn't yet clear, with the company's CEO suggesting that Sony's 'vertical structure for each product line' doesn't make expansion easy. But with rumours of a download-friendly PSP2 in the pipeline, that could be the opportunity Sony needs to get the ball rolling.

SOME people like a calm and quiet situation while watching their favorite movies, or listening favorite song, and even maybe playing videogames, and so on. In order to achieve such situation one may utilize their headphones.

There are a lot of brands and types that you can choose from nowadays, depending on the application.

Basically, a headphone has three parts: the driver, the earpiece and the attachment system. The driver is the ‘sound producer’. It is a transducer which converts electrical signal to the audio sound that you hear once you place the headphones on your ears. The earpiece is the physical part which you put to your ears. There are a lot of types of earpiece that you can choose from. Finally, the attachment system is the part which holds everything together. This can either be the headbands - for types which have one - or the wires which hold two ear buds together. The job of the attachment system if to make the earpiece somehow fit your ears.

Headphones can be attached to any music player, to mobile phones, to game consoles or to PC/Mac/notebook. If you want to get rid of the outside noise and you just want to concentrate on the sound, there are noise-canceling variants that you can choose from. The open-type headphones generally have better sound quality than the noise canceling type.
