Mini-Laptops

Mini-Laptops... Mini-Prices
A quick survey of the summer stock of mini-laptops turns up several rivals for your affection, either on the market or in preview form.
To this point in the history of mini-laptops, the Asus Eee PC 4G has been the category's poster child. In fact, MID madness really took off when the $399 Eee PC 4G debuted late last year. Asus made it happen by jamming an 800-MHz CPU, 512MB of RAM, and a 7-inch screen into a pint-size laptop PC about the size of a paperback book; the unit weighs about 2 pounds, and its dimensions are 8.8 inches wide by 6.5 inches deep.
Its price and compactness are certainly appealing, but achieving them entailed making some significant compromises. Two, in particular, stand out: The Eee PC 4G has a keyboard too tiny to accommodate adult hands, and its hard drive is very small (4GB). Subsequently, Asus released a version of the Eee PC 4G that runs on Windows XP; and most recently, it unveiled the slightly larger (and slightly pricier) Asus Eee PC 900-a $549 unit that manages to increase the screen size from 7 inches to 8.9 inches while remaining almost as small overall as its predecessor.

Blu-ray Disc

Blu-ray Disc (BD) is an optical storage disc media format. Its main uses are high definition media & data storage. The disc has the same dimensions as a standard DVD or CD.
The name Blu-ray Disc is derived from the BLUE LASER (violet coloured) used to read and write this type of disc. Because of its shorter wavelength (405 nm), substantially more data can be stored on a Blu-ray Disc than on the DVD format, which uses a red (650 nm) laser. A dual layer Blu-ray Disc can store 50 GB, almost six times the capacity of a dual layer DVD.
Blu-ray Disc was developed by the Blu-ray disc association, a group of companies representing consumer electronics, computer hardware, and motion picture production. The standard is covered by several patents belonging to different companies. As of April 2008, a joint licensing agreement for all the relevant patents had not yet been finalized.

Blu-ray Disc titles have been released in the United States, and more than 250 in JAPAN.
During the high defination optical disc format war, Blu-ray Disc competed with the HD DVD format. On 19th Feb 2008, Toshiba—the main company supporting HD DVD — announced it would no longer develop, manufacture and market HD DVD players and recorders, leading almost all other HD DVD supporters to follow suit, effectively naming Blu-ray the winner of the format war.

WiMAX

WiMAX the Worldwide Interoperability for Microwave Access, is a telecommunication technology that provides wireless data in a variety of ways, from point to point links to full mobile cellular type access. It is based on the IEEE 802.16 standard, which is also called wireless MAN. The name "WiMAX" was created by the WiMAX forum, which was formed in June 2001 to promote conformance and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL" (also to High speed packet access)

Hello friends..

Voice-over-Internet protocol (VoIP) is a protocol optimized for the transmission of voice through the Internet or other packet switched networks. VoIP is often used abstractly to refer to the actual transmission of voice (rather than the protocol implementing it). This latter concept is also referred to as IP telephony, Internet telephony, voice over broadband, broadband telephony, and broadband phone.
VoIP providers may be viewed as commercial realizations of the experimental Netwprk voice Protocol (1973) invented for the ARPANET providers. Some cost savings are due to utilizing a single network to carry voice and data, especially where users have underused network capacity that can carry VoIP at no additional cost. VoIP-to-VoIP phone calls are sometimes free, while VoIP calls connecting to public switched telephone network (VoIP-to-PSTN) may have a cost that is borne by the VoIP user.
Voice-over-IP systems carry telephony signals as digital audio, typically reduced in data rate using speech data compression techniques, encapsulated in a data-packet stream over IP.
There are two types of PSTN-to-VoIP services: Direct inward dialing (DID) and access numbers. DID will connect a caller directly to the VoIP user, while access numbers require the caller to provide an extension number for the called VoIP user.
