History of RDRAM marketing in PC market

In November, 1996, Rambus entered into a development and license contract with Intel.[3]. Intel announced to the Wintel development community that it would only support the Rambus memory interface for its microprocessors,[4] Intel was granted rights to purchase 1M shares of Rambus' stock at $10 per share.[5]

In 1998, Intel planned to make a $500 million equity investment in Micron Technology, to accelerate the adoption of Direct RDRAM.[6] Other investment included paying $100 million to Samsung Electronics in 1999.[7]

As a transition strategy, Intel planned to support PC-100 SDRAM DIMM on future Intel 82x chipset using Memory Translation Hub (MTH).[8] In 2000, Intel recalled the Intel 820 motherboard with memory translator hub (MTH) because the MTH can, while doing simultaneous switching, produce noise that may cause the computer to hang mysteriously or to spontaneously reboot.[9] Since then, no production Intel 820 motherboards contain MTH.

In 2000, Intel subsidized RDRAM by bundling retail boxes of Pentium 4 CPU with 2 RIMMs.[10] Intel began to phase out Rambus subsidies in 2001.[11]

In 2003, Intel introduced Intel 865 and Intel 875 chipsets, which were marketed as high end replacement of Intel 850. Furthermore, the future memory roadmap did not include Rambus.[12]

Few DRAM manufacturers have ever obtained the license to produce RDRAM, and those who did license the technology failed to make enough RIMMs to satisfy PC market demand, causing RIMM to be priced higher than SDRAM DIMMs, even when memory prices skyrocketed during 2002.[13] During RDRAM's decline, DDR continued to advance in performance while, at the same time, it was still cheaper than RDRAM. Meanwhile, a massive price war in the DDR SDRAM allowed DDR SDRAM to be sold at or below production cost. DDR SDRAM makers were losing massive amounts of money, while RDRAM suppliers were making a good profit for every module sold. While it is still produced today, few motherboards support RDRAM. Between 2002-2005, market share of RDRAM had never extended beyond 5%.[14]

In 2004, it was revealed that SDRAM manufacturers Infineon, Hynix, Samsung, Micron, and Elpida had entered into a price-fixing scheme .[15] Infineon, Hynix, Samsung and Elpida all entered plea agreements with the US DOJ, pleading guilty to price fixing over 1999-2002.[16] They paid fines totalling over $700 million and numerous executives were sentenced to jail time.

Rambus has alleged that, as part of the conspiracy, the DRAM manufacturers acted to depress the price of DDR memory in an effort to prevent RDRAM from succeeding in the market. Those alleg

Internet Service

The technologies used to connect to the Internet are different than those used for connecting devices on local area network. DSL, cable modem and fiber provide fixed broadband Internet service, while WiMax and LTE additionally support mobile connectivity. In geographic areas where these high-speed options are unavailable, subscribers are forced to use older cellular services, satellite or even dial-up Internet instead.

Wireless Local Area Networks

Wi-Fi is the most popular wireless communication protocol for local area networks. Private home and business networks, and public hotspots, use Wi-Fi to networks computers and other wireless devices to each other and the Internet. Bluetooth is another wireless protocol commonly used in cellular phones and computer peripherals for short range network communication.

Wireless/Networking Technlogy

Fundamental Computer Networks Concepts
In the world of computers, networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a combination of computer hardware and computer software. Some explanations of networking found in books and tutorials are highly technical, designed for students and professionals, while others are geared more to home and business uses of computer networks.

Types of Computer Networks
Networks can be categorized in several different ways. One method defines the type of a network according to the geographic area it spans. Alternatively, networks can also be classified based on topology or on the types of protocols they support.

General-purpose Technology

Nanotechnology is sometimes referred to as a general-purpose technology. That's because in its advanced form it will have significant impact on almost all industries and all areas of society. It will offer better built, longer lasting, cleaner, safer, and smarter products for the home, for communications, for medicine, for transportation, for agriculture, and for industry in general.

Imagine a medical device that travels through the human body to seek out and destroy small clusters of cancerous cells before they can spread. Or a box no larger than a sugar cube that contains the entire contents of the Library of Congress. Or materials much lighter than steel that possess ten times as much strength. — U.S. National Science Foundation

Nanotechnology

A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.
In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.

When K. Eric Drexler (right) popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a few nanometers wide—motors, robot arms, and even whole computers, far smaller than a cell. Drexler spent the next ten years describing and analyzing these incredible devices, and responding to accusations of science fiction. Meanwhile, mundane technology was developing the ability to build simple structures on a molecular scale. As nanotechnology became an accepted concept, the meaning of the word shifted to encompass the simpler kinds of nanometer-scale technology. The U.S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties

MOBILE TECHNOLOGY WITH CAMERA FACILITY

Mobile camera phone technology is evolving exponentially. Cellular phones started out as analog devices which only allowed people to make calls and send text messages. These days, we have smart phones which practically function as small computers. Even keypads on cell phones have even begun to disappear as touch screen phones become more prevalent.

Technological convergence is part of the evolution of mobile phones. Cell phones are no longer just simple communication tools. People now use mobile phones to surf the web or receive and send email. Most of today's mobile phones can play music, videos, and even provide directions through GPS. People also use mobile phones to take pictures or videos on a whim because many mobile phones now include a camera.

As mobile camera phones have become the norm, mobile phone makers have started to add high end camera features to handsets, such as flash, zoom, auto focus and the ability to take videos. Mobile phone manufacturers have also started to increase the number of megapixels. Users can now choose from regular phones that offer 2 to 3 megapixel cameras to high-end camera phones that offer 5 megapixel cameras. Extra powerful camera phones that offer up to 8 megapixels of resolution have also joined the competition. In addition, manufacturers have added other advanced features, such as face recognition technology, image stabilization, red eye reduction and the ability to upload photos directly to the web.

Pre multitask facility with Palm

Palm's WebOS delivers two important improvements that the iPhone can't yet match: true multitasking between applications, and a subtle notifications system that doesn't interrupt your train of thought. It does that while unveiling its own stamp on the multitouch user interface that Apple introduced to the masses with the iPhone and finding room for a slide-out hardware keyboard favored by CrackBerry addicts.

WebOS applications will be created with standard Web development tools such as CSS, JavaScript, and HTML that run on a version of the Webkit engine. This doesn't mean they are "Web applications," which require a connection to the Internet to work. It does, however, mean they are (in general) more lightweight and less-resource intensive than iPhone applications, which are developed using the Objective-C programming language

That may limit the performance of WebOS applications. Don't expect the sophisticated gaming community, for example, to embrace the Pre. But Palm's approach means it will be very easy for anyone who has developed a Web application to get up and running on Pre development, which could help expand the number of applications in the early days of the device if the smartphone world likes what they see.

Other mobile operating systems--notably Android and Windows Mobile--allow multitasking, but Palm has developed an elegant way of switching between "cards," something vaguely akin to a combination of Windows' Alt-Tab switching and Mac OS' Expose, or switching between tabs on a Web browser. New applications can be launched using the "Launcher" software button on the bottom of the home screen, and users navigate between different applications by flicking finger left or right Google
