The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the field of electronics engineering, and includes the hardware design side of computer engineering.
The study of new semiconductor devices and their technology is sometimes considered as a branch of physics. This page focuses on engineering aspects of electronics.
Overview of electronic systems and circuits
Electronic systems are used to perform a wide variety of tasks. The main uses of electronic circuits are the controlling, processing and dof information, and the conversion and distribution of electric power. Both of these uses involve the creation or detection of electromagnetic fields and electric currents. While electrical energy had been used for some time to transmit data over telegraphs and telephones, the development of electronics truly began in earnest with the advent of radio. One way of looking at an electronic system is to divide it into the following parts: More on [ Electronics ]

Virtual worlds:
Thu, 21 Aug 2008 11:47:15 -0000
Lively, Google’s virtual world, has been a flopIT SOUNDED like a brilliant idea. Google, the internet giant, would bring 3-D virtual worlds to the masses by making them accessible through a web browser. Millions of people log into virtual worlds such as World of Warcraft and Second Life every day, but they require special software and their complexity can be daunting to newcomers. So Google’s launch of Lively, in July, seemed to have great potential. But in the weeks since it opened its virtual doors, Lively has remained surprisingly lifeless, hosting a dwindling number of users and prompting a string of negative reviews.Lively is a simple environment, amounting to little more than a series of 3-D chat rooms. To enter, you must first download and install a plug-in for your web-browser. You can then choose from a list of rooms, the most popular of which are (inevitably) themed around sex and dating. And although some popular rooms—“Love Sweet Love” and “Sexy Babes Club”—have had thousands of visitors, the number quickly drops into the double digits further down the list. Hardly anyone is using Lively. ...
Dealing with the downturn:
Thu, 21 Aug 2008 11:47:15 -0000
Raising prices in straitened times calls for careful planningA COUPLE of years ago General Motors (GM), America’s biggest carmaker, swore it would no longer offer “employee discounts” on its vehicles. These large price cuts shrank bloated inventories, but they left buyers thinking that GM’s cars were worth far less than their list prices. Scrapping the discounts was part of ailing GM’s efforts to cure itself. But on August 19th the company reversed gear and reintroduced them, for a limited period, on nearly all its 2008 models and some 2009 ones.Although the move smacks of desperation, GM is not the only firm hoping that discounting can help it weather a sluggish global economy. On August 20th eBay, an online-auction site, said it would reduce the fees it charges sellers who post goods for sale on its site at a fixed price. The temptation in a downturn is to let prices slide to protect or increase market share. However, this approach can backfire if it triggers a price-cutting spiral. Moreover, managers often overestimate the extra sales that lower prices generate, so companies may be left worse off than before the cuts. That may help explain why a number of firms have been raising their prices, not cutting them—a trend that has contributed to a resurgence of inflation. ...
Jaguar Land Rover:
Thu, 21 Aug 2008 11:47:15 -0000
Despite hard times for the makers of big cars, JLR is happy under its new ownerWHEN Ratan Tata claimed ownership of Jaguar Land Rover (JLR) from Ford in early June, one of the first visits he made was to the Jaguar heritage museum at the British firm’s old site near Birmingham. The 71-year-old Mr Tata recalled that his father had bought one of its first XK120 sports cars in the late 1940s. Not only was the museum able to dig out his father’s order from the archives, it also took the chairman of the Indian industrial conglomerate for a spin in a similar car. It was the kind of personal touch that both the tradition-steeped car firm, and its new owner, hope will characterise their relations.Those relations may undergo an early test. When Tata Motors bought JLR for about $2 billion, it looked like a good deal. Thanks to Ford’s transformation of Land Rover, JLR had made profits of $650m in 2007. With its well received new mid-sized saloon, the XF, even Jaguar, a perennial lossmaker under Ford, was close to turning the corner into profit. In the first quarter of this year JLR rang up profits of $421m. ...
